THE PURPOSE OF WASHERS & WHY THEY’RE USED WITH FASTENERS
A washer is a mechanical component that consists of a circular flattened metal, plastic, or rubber disk with a hole through the middle. Washers are typically used with fasteners such as screws and bolts to distribute the load of the fastener, prevent damage to sensitive surface materials, and reduce the potential for leaks. Are washers necessary? That depends largely on the application and the substrate.
For more than 70 years, APM Hexseal has been creating innovative sealing solutions for customers in every industry. We leverage our extensive knowledge and hands-on experience to create cutting-edge sealing fasteners that meet the most rigorous expectations. In this article, we discuss the purpose of washers and their uses with fasteners.
THE PURPOSE OF WASHERS
Fasteners join two or more surfaces together through the use of threaded screws or bolts. Washers are incorporated into fastening hardware for everything from wooden furniture to automotive engines.
HOW DO WASHERS WORK WITH BOLTS?
To enhance fastener performance, a washer is placed on the bolt or screw between the head and the mating surface. In some applications, washers may also be placed between the nut and object surface.
