When shopping for washers, you may encounter swing “C” washers. They don’t look like traditional disc-shaped washers with a hollow center. Rather, swing “C” washers feature a C-like shape that allows them to swing open from the fastener or hardware with which they are used. Here’s everything you need to know about swing “C’ washers and how they work.
Overview of Swing “C” Washers
Swing “C” washers are fasteners with a concave, open center. They come with a bolt, which is used to tighten or loosen them. Swing “C” washers also have a hole in the center that supports a separate bolt or threaded fastener. A portion of the side has been cut out to provide access to this hole. This unique design results in a C-like shape, which is why they are known as swing “C” washers.
H0w Swing “C” Washers Work
Swing “C” washers work like most other types of washers by distributing the load of the fastener with which they are used across a larger surface area. The hole in the center of a swing “C” washer supports a threaded fastener, such as a bolt. You can fasten two or more parts, of course, by driving a bolt through them. Rather than only using a bolt, though, you may want to use a washer like a swing “C” washer.
The bolt will press against the top of the swing “C” washer, thereby distributing its load. As a result, the bolt’s load won’t be concentrated in a small area; it will spread across the entire top surface of the washer.
Benefits of Swing “C” Washers
While most washers can distribute the load of a bolt, swing “C” washers are unique because of their ability to swing open. You can easily insert or remove them — without completely removing the bolt itself.
To install a traditional washer on a bolt, you’ll typically have to remove the bolt first. Only then will you be able to place the bolt through the washer. Swing “C’ washers, though, simplify this process. You can install a swing “C” washer by loosening the bolt. With the bolt loosened, you can slide the open side of the swing “C” washer around the bolt.
Construction of Swing “C” Washers
You can find swing “C” washers made of different materials. Some of them are made of stainless steel, whereas others are made of high-carbon steel.
Finishes for swing “C” washers can also vary. Black oxide is a popular finish in which swing “C” washers are made. After undergoing this finishing process, swing “C’ washers develop a black tint that protects them from chemicals, corrosion and other forms of environmental damage.
