Square Hole Washers

Here at Phoenix Specialty Manufacturing, we manufacture custom washers, shims, and stampings for a wide range of industries based on our customers’ specifications. When you need custom washers, consider using square hole washers like the ones we offer.

The Why Behind Square Hole Washers

Square hole washers are used in an abundance of different applications, but one popular use is with woodwork and timber construction. They are specifically made to go underneath the head of a carriage bolt in softer woods. This way, when you tighten the nut, the bolt head doesn’t spin and cam out the hole.

We offer a wide variety of materials and thicknesses with our square hole washers. Whether you are looking for nylon, copper, or stainless steel, we’ve got you covered. Our washers can be made with thicknesses ranging in size from .0005” all the way to .260”. The diameters can range in size from .05” to 6”. Whatever your specifications are, we can manufacture it.
