Some people think that automotive fasteners are only useful in automotive industries because of its name. However, such items are also depended upon by aerospace, petrochemical, waste processing, pharmaceutical and even machine industries. Typically, a fastener is derived from materials most specifically metals like iron, aluminum, brass, nickel and stainless steel.

Automotive fasteners are defined as mechanical components in order to hold two or more structures together. They are classified further as nuts, screw, rivets, studs, pins and tie rods. Each of these classifications has its own distinct characteristics. More facts on some of these types of fasteners are discussed in detail through the succeeding paragraphs.

Automotive nuts

Nuts are examples of fasteners used in order to secure a bolt or screw to a certain surface. Depending on the application where it is to be utilized, the nut is classified. Some examples of nuts are also classified depending on its shape and design. In this regard, subcategories include hex nuts, wing nuts, cap nuts and t-nuts. Lug nuts, plate nuts, jam nuts and self-locking nuts are also popular in a lot of automotive industries.

Automotive bolts

These are generally classified as threaded automotive fasteners with threaded pins or rods. Typically, it is easy to detect a bolt because it contains a head on one of its end. Bolts are offered in the market in different sizes and may only be placed depending on the hole’s size where it is to be used. The most common types of automotive bolts are wheel bolts, U-bolts, mounting plate bolts and hub bolts. Rod bolts, lug bolts and radiator bolts are also included in the list.

Automotive washers

Just by hearing the term washer, one may not be able to comprehend well about why it is classified under the list of auto fasteners. Well, automotive washers are those that have small and flat dishes containing holes on its center and are used to hold a load of automotive bolts. It is often found below the nut or the joint in order to prevent leakage as well as distribute pressure. Common examples of automotive washers are bolt lock, hardened, cylinder head, lug nut and radiator washers.

Other types of fasteners

Aside from the three types elaborated above, there are yet other forms of fasteners offered in the market. Studs, for instance are those that have double-ended features and are fastened at both ends. These fasteners are classified according to where they are used and the material utilized to make up such industrial products. Other automotive fasteners are rivets, screws and tie rods.

Vehicle History Overview

  • They don’t make them like they used to.

The First Cars

  • The first motor cars were nothing more than a buggy and engine (Generally repaired by blacksmiths and carpenters. These cars were very expensive, which only the wealthy could afford)
  • Model T was the first car mass production on an assembly line in 1908 (Ford’s Vision was to produce an affordable car the average person could purchase)
  • Model T’s came in black only to keep the costs down. (The price came down once the assembly line was streamlined, but in 1908, the cost for a Model T started at $825. By 1913 the cost of the car reduced to $550)

Cars in the 1960s

Cars were made the same basic way up through the 60s

  • Body Over Frame
  • Rear Wheel Drive (Same concept, but the cars were very big, bulky, and heavy)

Except people in the 60s wanted SPEED! They achieved this with Big Block Motors, which created a lot of Horsepower. (The Birth of Hotrods, Rat Fink, Flames, and Pin Striping).

Cars in the 1970s

  • The government place strict fuel economy and emissions control laws
  • Customers demanded cars with increased fuel economy
  • New laws and customer demands started the automotive explosion of engineering ideas and changes in the automotive industry

Changes to comply with Demands and Laws

  • Smaller bodied cars and smaller engines
  • Aerodynamics (Increase Fuel Mileage)
  • Lighter cars by using different materials and designs
  • More work-hardened areas created during formation of panel (Body Lines)
  • Safety

Construction of Interstate Highways + Higher Speed Limits + More High Performance Cars = Accidents and More

Deaths from Auto Accidents

Federal Laws were passed to regulate safety. These laws included:

  • Installation of seatbelts
  • Safety glass windshields
  • Head restraints
  • In 1979, the first driver side airbag was introduced
  • Airbags are mandatory in motor cars produced after 1990
  • Unibody Torque Boxes: Allow controlled twisting and crushing
  • Crush Zones: Made to collapse during collision (To act as an absorber, absorbing the impact)

Modern Day Cars

  • Carbon Fiber Parts
  • Aluminum Parts
  • More Plastic Parts
  • High Strength Steel
  • Boron Steel
  • Unibody Construction
  • Space Frame Construction
  • Computer
  • Hybrid Cars

Now they even have cars that will tell you when you’re lost, where to turn, Parallel Park for you.

Conclusion

While the modern day cars appear to be made cheap and unsafe, they are actually designed to crush or collapse, while transferring the energy around the stronger passenger compartment to protect the passengers from injury.

There is considerably more damage to modern day cars during a collision than the older vehicles, which gives the perception that “they don’t make them like they used to”. However, in reality the cars are taking the impact instead of the passengers.

The lesson was designed to give you a little history, but to also emphasize that just a hammer, dolly and a few wrenches are not going to repair today’s cars. We need highly trained collision repair and automotive technicians to repair today’s vehicles.

 

OE: Original Equipment:  This part is either made by the car manufacture or is made by an automotive part supplier and is branded with the car manufactures logo and/or in the car manufactures box.

OEM Original Equipment Manufacture

OES Original Equipment Supplier

Car manufacturers do not make all their parts that they put on their vehicles during assembly or repair, they contract out to auto part manufactures to make parts for them. For the most part the car manufacturer makes the body, frame and major engine components the rest they ‘farm out’ to OEM/OES manufacturers. The car manufacturer provides the specifications to the OEM/OES manufactures for the parts they need. The OEM/OES manufactures the part to these specs, adds a logo and ships it to the car manufacture.

Bosch, Bilstien, Boge, Beru, Mann, ATE, to name a few, are all OEM or OES suppliers to the car manufacturers. They make parts from spark plugs to exhaust parts. The difference between OE and OEM/OES is mainly the OEM/OES usually don’t have the car manufactures logo, but they are the same exact part. Sometimes the logo is ground off the part by the OEM/OES company so as not to affect there contract with the car manufacture. Same part coming off the same assembly line as the OE part does.

The OEM/OES parts are less expensive because they do not go through the car manufactures part system. Every time an OE part goes through a depot, warehouse, dealer, there is a little more money added to the cost of the part. This is the major reason that OE parts cost more. OEM/OES do not go through this procedure, our buyers get them directly from the manufactures, keeping the prices down.

Aftermarket:¬†aftermarket parts are just that, aftermarket. They are not made by the car manufacturers. They can be made by one of the original equipment manufacturer companies or by a completely different manufacturer. The main difference is they are not made completely to the car manufacture specifications. This is not always bad. One example is Bilstien. They are an OEM/OES supplier, but they offer aftermarket parts also. There HD struts/shocks are original equipment, but their Sport struts/shocks and suspension kits are not made to OE specifications, better but not OE, so it’s now an aftermarket part. Another example is the Stewart EMP BMW water pumps. Stewart EMP is NOT an OEM/OES manufacturer but the pump they make is better and stronger than OE. It is an aftermarket part but a better part altogether.

But still another example of an aftermarket BAD part is a counterfeit part. Counterfeit part manufacturers use backward engineering to get the specifications of the part without paying the car manufacturer. And almost all the time these parts are made with very low quality components. Sometimes these parts are very hard to identify because a lot of emphasis is put on the look and feel of the part and not what it is made from. One way to identify an counterfeit part is its unbelievable low price, the old adage you get what you pay for fits here. The best way to avoid these cheap low quality parts is to purchase your parts from a reliable source, one that offers a warranty and return policy.

Almost all Performance parts are aftermarket parts, again be careful with these parts also. Buy from a reputable supplier or/or manufacturer.

 

Here are the different types, available from garage equipment supply dealers:

In-Ground

This type of vehicle lift is assembled below the garage floor. It consists of one or more pistons, depending on the maximum weight capacity. Lifts with one or two pistons are used for compact, mid-sized and full-sized cars. Lifts with three or more pistons are used for larger vehicles, such as buses and RV’s.

Two Post Surface Mounted

The most common vehicle lift utilized today is called a Two Post Surface Mounted lift. On each column, there are lift arms. These are controlled mechanically, electronically or hydraulically.

Multi-Post Runway Automotive Lift

The most common type is the four-post mounted lift, which is extensively used by oil change, transmission, and muffler service shops. You’ll find this type of auto lift in wheel alignment service stations as well. The car is driven onto the two runways and raised, exposing its underside.

Low/Mid Rise Frame Engaging Lift

This type of vehicle lift engages the vehicle’s frame in lifting. There are two ways this type may operate. One way is scissors-style, moving straight up. Another is parallelogram-style, moving forward or backward, while raising or lowering. This type is commonly used for brake, tire, and wheel services as well as auto body repair.

Drive-On Parallelogram

The Drive-On Parallelogram is a surface-mounted vehicle lift. It has two runways where the wheels of the car should be placed. It has a lifting mechanism that moves the vehicle a short distance forward or backward while raising or lowering. The direction depends on the way the lift is mounted.

Scissor Lifts

The Scissor Lift can either be of a fixed pad type or a roll-on frame/underbody engaging type. It has a lifting mechanism that’s similar to the parallelogram lift. Their main difference is that the scissors lift goes up and down on a straight vertical path.

Movable-Type Wheel Engaging Lift

This type of vehicle lift is used for vehicles that are longer than conventional cars, such as buses and trucks. It consists of several lifting columns in sets of two, four, six, or more. The columns can be moved and connected with the other columns so that their movements are synchronized.

 

You might be surprised to learn that there are different types of locksmiths around. This is essential especially for those who want a more specialized service. Residential, commercial, automotive and forensics are the types of locksmiths that are accessible although the forensic ones are rare as they usually work with investigative agencies or law enforcement agencies.

Residential

Residential locksmiths are experts when it comes to making the home safe and secure. As most homes have the regular locks installed near window frames, it might compromise the safety of the family. These experts can install a double cylinder lock that needs a key inside for the door to open to give extra security. Aside from this base-knowledge they can also re-key locks as well as have them replaced in such a way that these are not easily tampered. They can also do entry gates, screen doors, sliding as well as emergency services.

Commercial

A commercial locksmith specializes in locks that are manufactured for business purposes. Examples would be installation of panic bars, replacing locks in file cabinets, installation of automatic door closer, safe/vault installation as well as installing a master-key system. Panic bars are especially important as they would provide workers a means to exit the building premises in case of emergencies.

Automotive

Automotive locksmiths are the ones that you go to if you ever need a spare car key or want a replacement when you’ve lost the original car key. These experts can help automotive owners in choosing the right type of car keys that would best suit their needs. Most automotive locksmiths are familiar with transponder car keys and can also do re-programming at a lower price compared to the same service that car dealers offer. Aside from transponders, they can also unlock cars, change or replace ignition locks, provide laser cut keys and even offer lock services for high security vehicles.

Services

In choosing the locksmith that would best suit your need(s), it is important to deal with a company that is licensed and has done background checks on their employees. This is to make sure that the company that you would be transacting with is legal and since some items in the house might be valuable or important documents are inside vaults or safes, one is assured that the person they are dealing with is someone who they can trust. Consider talking with someone who knows a reputable locksmith especially if you’ve just moved in or purchased a new home or office.
