Profile: Willie Washer Manufacturing Corporation is a manufacturer of special washers, stampings and machined parts. Our round flat washers are used to span over-sized holes, and can spread loads over wider areas. They prevent surface damage and embedment from nuts & bolts, and provide a consistent surface for more predictable joints. They can also be used as shims to compensate for tolerance variations. We are an ISO 9001:2015 certified company. Our stainless steel square washers are utilized to protect surface finishes and spread loads in a fastener assembly system that utilizes square headed fasteners.
