Professional Applications & Engineering Value

This 316 stainless steel split lock washer delivers critical vibration resistance in demanding industrial settings where equipment reliability is paramount. The standard split lock washer type creates continuous spring tension against both the bearing surface and fastener, effectively preventing rotation and loosening under dynamic loads. Engineered for 1 3/4" screw size applications, the precise 1.789" ID and 2.679" OD dimensions ensure optimal load distribution while the Rockwell C35 hardness provides exceptional wear resistance. The 316 stainless steel material offers superior performance in corrosive environments including chemical processing, marine applications, and outdoor installations where moisture and chemicals would compromise ordinary fasteners. This combination of precise engineering and premium materials solves common industrial challenges of fastener failure, maintenance downtime, and equipment safety concerns.
