These thick washers are designed to support structural screws, studs, and nuts. They meet ISO 7416 (formerly DIN 6916), which is an international standard for washer dimensions. Use them with DIN 6914 structural hex head bolts and DIN 6915 structural hex nuts.

Hot-dipped galvanized steel washers have a thick coating that holds up ten times better than zinc plating in wet environments. Since they are strong and rust resistant, these washers are often used for construction and on building exteriors.

As a screw is tightened, these washers flatten to add tension to the joint and prevent loosening from small amounts of vibration.

Hot-dipped galvanized steel washers are 10 times as corrosion resistant as zinc- and zinc yellow-chromate plated washers.
