The difference between interior vehicle fasteners and exterior fasteners

July 30th, 2021 | Technical | Comments Off on The difference between interior vehicle fasteners and exterior fasteners

The world of automotive fasteners is a fascinating place with so many kinds, designs, types, and uses. The average car has a few thousand fastener units installed during production, which holds the vehicle together as well as provides easy de-installation if needed. However, there is a specific difference between the fasteners used in the interior and the car’s exterior, and in this article we explore the difference in more detail…

Automotive Fasteners Used In The Exterior

Fasteners used on the car body or in the engine bay are a wide selection of nuts, bolts, screws, springs, and clips which have the sole purpose of firmly positioning components or allowing controlled movement of some parts. When used in the exterior, it’s imperative to make them dependable and easily changeable. However, one of the most critical aspects is to make them durable since exterior fasteners are exposed to the elements, water, chemicals and extreme temperatures, just like those used in the engine bay. That is why metal is the material of choice for the areas exposed to extremely high temperatures (engine bay) or severe forces (suspension). However, plastic is still widely used for making exterior fasteners since it is lighter and doesn’t corrode. So, almost all outer clips, washers, and fasteners used for connecting plastic parts of the body, bumpers, trim pieces, and so on are manufactured from composite materials.

Automotive Fasteners Used In The Interior

In the interior, fasteners have the same job: holding the door cards, dashboard, trim, and panels in place, but the material choice, construction, and requirements are usually a bit different. While metal fasteners are widely used on the outside of a vehicle, plastic is the top choice for interiors. There are several reasons for this decision. Firstly, since internal fasteners are not exposed to high forces, temperature or chemicals, plastic is a perfectly sound choice. Secondly, the fasteners used in the interior have to be a bit softer and have more play, so the interior feels more comfortable, plusher and isolated. The third reason, and it is the most important, is safety; in the unfortunate case of an accident, plastic fasteners can bend easily and help protect the occupants.

Automotive Fasteners Used in Motorsport

July 12th, 2021 | Technical | Comments Off on Automotive Fasteners Used in Motorsport

Over the decades of motorsport, racing cars were always laboratories of four wheels that served to test and develop various components. If a specific part endured repeated torture on the track, it was good enough to use in everyday vehicles in mass production. Just like in civilian cars, fasteners are a small but essential part of the championship-winning formula, and in top-notch racing series, constructors pay much attention to them. Today, we will tell you more about the different fasteners used in motorsport.

Racing Approach

Firstly, although the fasteners in road-going vehicles and in racing machines serve the same purpose, there is a significant difference in approach and design. First of all, racing fasteners are either made of higher-strength materials or metal, which is more durable. The reason is simple: race cars achieve incredibly high speeds and generate an insane amount of heat, requiring all fasteners on the vehicle to be up to the task. You don’t want your body panels flying off at 200 mph or hearing a suspicious rattle just when you want to overtake somebody for the chequered flag.

Secondly, fasteners have to have a quick-release function on some vehicles since there is a chance that the pit crew needs to replace a part, body panel, or component. Often in the heat of battle, cars swap paint and bump into each resulting in cracked bumpers or damaged front splitters and spoilers. In that case, the pit crew is ready to take the part off and replace it with a brand new one. Using special “quick release” fasteners, it is possible to replace the whole panel in just a couple of seconds, something that couldn’t be done on a regular vehicle.

Thirdly, although race cars use a more advanced set of fasteners, not all kinds are needed for this application. For example, race cars don’t need plastic fasteners that go in the interior and hold door cards or dashboards. Simply, because race cars don’t have an interior or conventional dashboard.

High-Quality Materials

As we mentioned before, automotive fasteners used in motorsport need to be highly durable and withstand extreme heat and forces. For such purposes, manufacturers use high-strength plastics or metal simply because metal can endure higher temperatures. In some cases, aluminum is also used. This leads us to an exciting point that fasteners in motorsport have more in common with those used in the aerospace industry since the requirements are as high and forces they need to withstand are as strong.

One of the critical points in constructing fasteners for motorsport is their weight. In most cases, the weight of a single bolt, spacer, or spring is not relevant, but when you are constructing an extremely expensive race machine from scratch, and you want to find every single way to have a competitive advantage over the rest of the grid, every gram matters.

Types of Motorsport Fasteners

The most common fasteners used in race cars are springs, quick-release latches, rivets, washers, pins, locks, and clips. Most of those are made of metal. For example, the rubber hooks (for holding the bonnet) are also used due to their ability to soften the vibrations.

Types of Automotive Fasteners

June 2nd, 2021 | Technical | Comments Off on Types of Automotive Fasteners

When we think of automotive parts, we often visualise various engine components, bulky doors, or wheels. But the truth is that the average vehicle consists of over 30,000 small parts, most of which fall in the automotive fastener category. The fasteners are a generic term for all bits and pieces like bolts, nuts, screws, spacers, or springs used in practically every car component. Even though the fasteners are small, they are not insignificant, quite contrary. There are over 64,000 of different designs which are used throughout the industry, and there is no vehicle on the planet that would be able to function correctly if it wasn’t for those invisible mechanical heroes. In this article, we explore some of the most common types of fasteners used in the automotive industry.

Automotive Fasteners According To Material

Metal Fasteners – Iron or aluminium alloy (sometimes copper) is the most common material in the automotive fastener world. Bolts, screws, nuts, and springs are all traditionally made out of metal. Those kinds of fasteners are usually more durable and reusable and used for the firm position of heavy items,engine parts, and suspension components. Most bolts are also covered in zinc for rust protection and durability.

Plastic Fasteners – Plastic is a very popular material in this industry, and numerous types of connectors, pins, spacers, and washers are produced used plastic or composite materials (sometimes rubber). Due to the brittle nature of the plastic, that kind of fasteners is often designed for single-use, and when they are removed, it is not recommended to be used again.

Most Common Automotive Fasteners in Use

Nuts and Bolts – The average car consists of a thousand nuts and bolts of all sizes used in its every corner. The nuts and bolts are used to hold engine components,suspension arms, and dashboards, amongst other things. Simple but irreplaceable, millions of them are produced each day using various iron and aluminium alloys.

Washers – A washer is a thin plate (metal or plastic) that is used in conjunction with a nut and bolt. Its primary purpose is to distribute the load or pressure created by the bolt. It is an extremely simple fastener, and it is often round in shape with an appropriate hole in the middle.

Screws – Screws are commonly used for positioning and tightening panels or components. The head of the screw can differ, and it can require different tools. Just like nuts and bolts, screws are almost exclusively made out of metal and used throughout the automotive industry.

Clips – Clips are very important in the modern car industry since they often replace the nuts and bolts and provide car manufacturers with more straightforward solutions. There are numerous designs for various purposes, but clips can be made out of plastic or metal. Most commonly, clips are used for positioning of exterior trim on a vehicle (metal) or for holding the interior panels, door cards, or plastic bumpers (plastic). Some clips are not reusable, while others are.

Clamps – Clamps are a very important member of the fastener family since they are often used in an engine for holding the hoses and tubes. The classic clamp design is made of metal with a screw to tighten the clamp and firmly hold the hose in place. There are few other designs, and some even made out of plastic, but this one is most common in all vehicles.

Rivets – Rivets are used in car production as well as in aftermarket and repair processes and have the simple task of firmly holding on two pieces of metal or plastic together. Most rivets are made from metal, but plastic ones are used for plastic bumpers or trim pieces. Rivets cannot be reused.

Springs – Made exclusively out of metal, springs are a simple type of fastener used to create tension between two mechanical components.

Pins – Designed to keep the components in place but still allow some movement, pins can be made out of plastic or metal. Metal ones are commonly reusable, but plastic can be destroyed when removed.
