What Are Plastic Fasteners and What Are They Used For in Automobiles?
Plastic fasteners are affordable, lightweight, and corrosion-resistant components used for many purposes, including joining and securing parts together. When used in cars, plastic fasteners reduce the overall weight of the vehicle, dampen noise and vibrations, and resist heat, moisture, and chemical degradation. When it comes to using plastic fasteners in cars, this versatility usually applies to either holding various trim pieces to the body or securing various parts of the engine to other parts of the vehicle.
Automotive manufacturers rely heavily on these fasteners for several reasons, including being cost-effective, easy to install, and available in many different configurations internally and externally.
Types of Automotive Plastic Fasteners
There are many different types of fastening systems specifically designed for automobiles. The specific type of fastener has a specific application; for example:
- Plastic Rivets: These types of fasteners are used primarily to secure the interior trim (such as dashboard panels), bumper covers, and wheel well liners.
- Push-Type Clips: These reusable fasteners are typically used in splash guards or under the hood for fixing hoses to the engine.
- Plastic Screws (Fasteners): A fastener that is used when a screw type of thread-type fastening is needed; for example, attaching light assemblies or dashboard components.
- Cable Clips: Primarily used to hold wiring and hoses in an organized manner to assist with maintaining safe routing.
- Trim Retainers: Used to attach interior and exterior trim without the use of adhesives or metal screws; very important to keep the trim in place.
Wholesale Automotive Fasteners
If you are an automobile workshop owner or supplier, purchasing automotive plastic fasteners in bulk is usually an intelligent purchase. By purchasing fasteners at wholesale prices, you can save money; not only that, but you will also have a wide range of types readily available to you. Many online retailers and specialized automotive supplier companies offer wholesale pricing for smaller and larger operations.
When purchasing wholesale, verify the quality of the material used in the manufacture of the fastener. Some commonly used materials include nylon, polypropylene, and acetal; all excellent materials because of their durability and resistance to weather.
How to Remove Automotive Plastic Fasteners
Removing plastic fasteners can be difficult without causing any damage but can easily be accomplished by using the appropriate tools and methods; although some common household tools such as screwdrivers could also be used occasionally, it is recommended that you use specially designed removal tools to achieve better results. The purpose of these removal tools is to slide underneath the fastener and remove them without scratching or damaging the adjacent parts of the vehicle.
Here’s a simple process for removing a plastic fastener:
- Identify which type of fastener you have; is it a push pin, clip, or screw type?
- Use the correct fastener removal tool (a trim removal tool or a fastener remover) to gently pry off the fastener.
- Be sure to take your time and be careful not to break the fastener or damage the area around the fastener.
- If the plastic fastener is damaged, have a replacement on hand before continuing with your project.
Tips on Choosing Plastic Fasteners for Your Car
Material Quality: When selecting plastic fasteners for your car’s interior and exterior, choose high-quality materials such as nylon for high-temperature applications and UV-resistant plastics for exterior parts.
Fit Size: Ensure that the fit size for the plastic fasteners is correct for the location you want to use them and that a plastic fastener that does not fit correctly will affect the integrity of the part.
Application: Some plastic fasteners are designed to work only in certain applications; you need to review the compatibility of each of your plastic fasteners against the make and model of your car before making a purchase. There are several online retailers and auto parts suppliers that have compatibility charts, so they will be very helpful in your search for the right plastic fasteners.
How to Maintain and Replace Plastic Fasteners
Like any other part of your car, plastic fasteners can wear out or break over time as well. Therefore, you should inspect your plastic fasteners regularly to ensure that they are intact and secure (there should be no signs of damage, cracking, or wobbling). Whenever you find that a plastic fastener has become damaged, you must replace it as soon as possible in order to prevent damage to the remainder of your car’s components. You should always keep a supply of universal fasteners in case of emergencies so you won’t find yourself in a situation where you have to replace a plastic fastener and not have one available during a repair or maintenance.
You can extend the life of plastic fasteners for your car by not overtightening plastic screw fasteners, which will strip the plastic threads and eliminate the integrity of the fastener. In addition, you can help extend the life of all plastic fasteners by keeping them free from grease and debris, which can cause fasteners to no longer work effectively.
