Professional Applications & Engineering Value

This M16 split lock washer delivers critical vibration resistance in demanding industrial environments where fastener loosening can compromise safety and operational integrity. Engineered to DIN 127B standards, the steel construction with Rockwell C44 hardness provides exceptional spring tension that maintains bolt preload under continuous vibration and thermal cycling. The split lock washer design creates constant friction against both the bearing surface and fastener head, effectively preventing rotational loosening in machinery, automotive assemblies, and structural applications. Particularly valuable in metric fastener systems requiring reliable locking performance without additional threading or chemical adhesives.

Specification Summary & Compliance

Manufactured to exact DIN 127B specifications with 17mm inner diameter, 27.4mm outer diameter, and 3.3-3.7mm thickness tolerances. The standard split lock washer type provides consistent performance across industrial applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries while maintaining the mechanical properties required for reliable locking performance.
