Professional Applications & Engineering Value
This M12 split lock washer delivers critical vibration damping in machinery, automotive, and industrial equipment where constant motion threatens fastener integrity. The curved split lock washer design generates continuous radial pressure against both bearing surface and fastener, maintaining clamp load despite dynamic stresses. Manufactured from high-grade steel with Rockwell C44 hardness, it withstands repeated compression cycles without permanent deformation. The DIN 6905 standard ensures dimensional precision for seamless integration in European-engineered systems, while the metric sizing (11mm ID, 19.7mm OD) guarantees proper seating on M12 fasteners. This engineered solution prevents costly downtime by eliminating the need for frequent retightening in vibration-prone applications.
Specification Summary & Compliance
This split lock washer features precise metric dimensions: 11mm inner diameter, 19.7mm outer diameter, 2.1mm thickness, and 3.7mm overall height. Manufactured to DIN 6905 specifications for dimensional accuracy and performance reliability. The washer demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications. The Rockwell C44 hardness rating confirms consistent material properties and spring performance across production batches.
