What Are Seat Washers?

Seat washers are specially contoured or flat washers used in high-strength bolted connections to distribute load, maintain alignment, and prevent bolt loosening. Often used with HSFG bolts and tensioned assemblies, they ensure a firm grip between the bolt head or nut and the steel surface, improving joint stability and fatigue resistance.
