Ogee washers are commonly used in wood and dock construction and usually made from cast iron and hot dipped galvanized for added corrosion protection in harsh environments. They have a large, over-sized bearing surface that is designed to prevent bolt heads and nuts from pulling into the wood. Due to the size and shape, they are generally manufactured as a cast iron product in accordance with ASTM A47 or A48. Shop our selection of bulk ogee washers with sizes ranging from 1/2” bolt size up to 1-1/2” bolt size.
