These square washers are expertly designed to distribute load evenly and provide critical protection against the crushing of wood fibers. Measuring 2-1/4 inches square with a thickness of 3/16 inch, they create a smooth surface against the nut, significantly reducing the likelihood of loosening. Made from durable galvanized steel in compliance with ASTM standards, they feature a generous 11/16-inch diameter hole suitable for use with 5/8-inch bolts. Ideal for installation in various aerial hardware applications, these washers enhance stability and longevity in your projects.
