Specifications for Ribbed Lock Washers

Ribbed lock washers solve the problem of securing screw connections. The valuable properties of the steel spring washer are supplemented by a patented serrated profile. This S and VS series provide maximum security against slackening through vibration. The smoothly rounded serrations uniformly press against the contact surfaces of the bolted connections, gripping them securely without damage. As the joint relaxes the deflection of the spring (H - S) maintains pressure on the nut and the inherent friction on the serrations gives additional protection against loosening.

S - Series (Standard duty), VS - Series (Medium Duty)
Standard Finish: Spring Steel, hardened, black finish. Also available: Stainless Steel, Phosphor Bronze, Zinc and Cadmium plating
