Square Washer Specification

Washers are typically thin pieces of material with a hole in the middle that is used to distribute the load of a threaded fastener, such as a screw or nut. They can also be used as a wear pad, to reduce vibration, or as a locking device.

Heatfastener square washers can be manufactured with outside diameters anywhere from .05″ to 6.” We can even produce thicknesses from .0005″ all the way up to .260.” We have over 300 raw materials in stock, so you can feel confident we’ll design the perfect square washer for you.

One benefit to using square washers is their durability. In the architecture industry, square washers are often used in constructing buildings, because testing has shown that square washers will function better than a round washer during an earthquake. Round washers tend to fold up and split during an earthquake, especially when the sill plate hole is oversized. Square washers, on the other hand, won’t have this issue.

Square washers are used for limited space applications where a standard washer will not fit. The flat sides can also prevent the washer from rotating.

Types Of Square Washers

Square washers are beneficial to use instead of standard round washers when leveling, or alignment is needed for an application. Like round washers, square washers are often used to distribute a larger load, but they also perform as shims and add the advantage of providing edge-to-edge contact to resist turning, as well as providing a larger bearing surface as compared to a round washer.

Bevel washers are square or rectangular washers with a beveled 1 to 6 ratio surface, to compensate for a lack of parallelism in structural components. The beveled surface allows for a snug fit between both the flat and the sloped material that is being bolted together, which creates a solid and tight fit overall.

Square Washers called construction square plate washers can be used instead of the round washers for applications such as timber buildings and concrete floors; they are used with all fasteners for larger load distribution and bolting through a wall or timber. While disc washers operate solely as load distributors, square flat washers serve a second role. Their thick metal forms have that standard bolt opening in the center, plus a wide surface area, a feature that spreads torque and head load, but they also perform as shims. That means the bolt crown can be lifted away from the anchored part. It also means that a multi-surface project won’t deform or bend when the fastener is tightened.
