Countless Applications for Quality Washers
Our washers are highly versatile. Here are a few common applications:
- Beveled washers are commonly used in applications involving an I-beam, as they can be easily attached through the flanges.
- Countersunk finishing washers are ideal for applications where smoothness and appearance are important factors. They can be used with flat and oval head screws for wood and metal applications.
- Dock washers are thick washers that can are often used in the building or repair of docks.
- External tooth lockwashers have teeth that extend outward so that they can easily bite into the bearing surface. This is a very useful feature for applications in which the bolt should never loosen.
- Fender washers are thin flat washers that are commonly used to provide a wide bearing surface.
- Flat washers refer to a group of washers that are flat and smooth, capable of dispersing load in a variety of applications.
- Internal tooth lockwashers are commonly used to firmly secure the screw and nut connection and prevent it from loosening over time.
- Internal/external combo tooth lockwashers combine the benefits of both types of lockwasher and add a great deal of protection against loosening.
- Metric washers are flat washers for use with hardware with metric-style threading.
- Shoulder washers include an extended sleeve on the internal surface. This can be inserted into the adjacent material, which helps to insulate metal screws in electrical applications. This also reduces friction between parts.
- Split lockwashers are made with a divide that serves a similar purpose as an internal tooth lockwasher, preventing loosening and slipping.
- Structural washers are made from high-grade steel and are heat treated, making them perfect for use with structural bolts and nuts.
- Thru Hard washers are heat treated and made for heavy-duty use. These washers have exceptionally high tightness tolerance.
