Overview

This DIN 25201 lock washer is a precision-engineered, high-strength fastener component designed to prevent loosening in critical, vibration-prone assemblies. Manufactured from hardened carbon steel and finished with a durable Dacromet coating, it delivers exceptional locking force and corrosion resistance. The defining feature is its expanded outer diameter, which provides a larger bearing surface for improved load distribution and enhanced security compared to standard washers. It is the reliable solution for maintaining clamp load and joint integrity in demanding industrial environments.

Key Features

Expanded outer diameter design for superior load distribution and locking performance Hardened carbon steel construction with a hardness rating of 440-500HV for high strength Dacromet (zinc flake) finish provides excellent corrosion resistance without hydrogen embrittlement risk Conforms to the precise dimensional and performance standards of DIN 25201 Engineered to prevent bolt and nut loosening under severe vibration and dynamic loads
