Plate Washers

Plate washers are commonly used in wood construction to prevent bolt heads or nuts from pulling into the wood. Square plate washers are also available. A plate washer is used in a variety of projects including: marine and timber.

Round plate washers are simply a low carbon steel, oversized cut washer designed to provide a larger bearing surface than an F844 standard flat washer.

Diameters: 1/2″ – 1″ (round)
Origin: Import
Finish: Plain and hot-dip galvanized

Square plate washers are made from low carbon steel and have a larger surface area than round washers. Since they develop more friction when tightened against wood, this type of washer is specified for seismic applications. They are often found in timber construction. Stock sizes are available for bolts from 1/2″ to 1″, with a thickness of .195″ up to .395″. For the best corrosion resistance, hot-dip galvanized plates are recommended.
