Plastic Fastener Applications in the Automotive Industry

June 17th, 2021 | Technical | Comments Off on Plastic Fastener Applications in the Automotive Industry

Hidden from the spotlights of the industry, automotive fasteners are silent heroes, which hold practically every car part together. Even though the most common material in the fastener industry is metal, zinc, or brass, the number of items made of plastic is increasing as we speak, bringing numerous advantages to engineers and users. In this article, we explore the various applications of plastic fasteners in the automotive industry.

They Have Been Around For a Long Time

Plastic as a material has a long history in the car industry. After WWII, plastic started having widespread use, but it was still a pretty new and expensive material back then. With the improvements in production, different types of plastic started emerging, and it became a household material by the late ’60s, early ’70s. Today, more and more parts, components, and fasteners have been made out of plastic. Experts claim that this is a future material since the development of metal as materials is pretty much coming to its limits.

The Advantages Of Plastic Automotive Fasteners

Plastic has proven to be a much more durable material than metal and is chemically and thermally resistant. This is very important since it means that plastic will not melt (some types, at least) when treated with high temperatures in the engine bay and will not rust when used in the car’s exterior or undercarriage. Of course, not all types of automotive fasteners can be produced out of plastic, but since the majority can, they also offer a significant weight reduction over metal fasteners. Even if the weight difference between a single metal and a plastic unit is tiny, modern cars use thousands of fasteners, which can add up, making the complete vehicle lighter and more efficient.

The significant advantage is that plastic fasteners are somewhat cheaper and faster to produce and can be engineered to work with the car’s passive safety features to provide better results in accidents.

The Disadvantages of Plastic Automotive Fasteners

Even though plastic is a superior material in some cases, it is not the definitive choice in the fastener industry simply since it has its limits. First of all, you cannot make any type of fastener from plastic and, for example, plastic springs will be terribly unreliable. Secondly, when used as a part of a more significant mechanical device (like an engine), plastic is just not as rigid as metal and cannot withstand heavy-duty use.

There is also a question of recyclability, and since the global car industry is moving towards sustainability, plastic fasteners are, in most cases, more complicated to recycle than metal ones. At the moment, top automotive fastener manufacturers are working hard to discover innovative materials that would be as durable but easier to recycle or re-use.

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 cooper) 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.
