Square Washers
Featuring a heavy-duty square profile, these washers are the industry standard for timber construction and structural steelwork. Their large surface area is designed to spread high-tension loads across wood grains, preventing the fastener from crushing the timber in roofing, decking, and heavy framing applications.
