What Is a Serrated Washer?
A Serrated Washer is a type of locking washer featuring sharp teeth on one or both sides. These serrations bite into the mating surfaces, increasing friction and preventing loosening in dynamic or high-vibration environments.
Our Serrated Washer Manufacturing Method
Fasteners India follows a controlled manufacturing process including material selection, precision stamping or machining, heat treatment, surface coating, and final inspection to ensure uniform serration depth, consistent hardness, and reliable locking performance.
