The Square Screw Washer is offered by us that is square in shape and may be flat on both sides or flat on one side and beveled on one side. Often used with square head bolts, square washers prevent pull through and provide a larger surface area and greater hold than standard round flat washers. The washers have a large bearing surface that distributes stress and clamping force over a wider area. The washer is easy to install and made for use in the various commercial and industrial uses. The Square Screw Washer is high quality and is very durable.
