Professional Applications & Engineering Value
This zinc-plated steel split lock washer addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and heavy equipment applications. The DIN 127B standard ensures precise dimensional control with 17mm internal diameter and 27.4mm outer diameter, providing optimal load distribution while the split design generates continuous spring force that compensates for settlement and thermal expansion. The Rockwell C44 hardness maintains locking performance under dynamic loads, making these metric washers ideal for M16 fasteners in vibration-prone environments. The zinc plating offers sacrificial corrosion protection, extending service life in exposed or humid conditions where secure fastening is critical to operational safety and maintenance intervals.
Specification Summary & Compliance
This split lock washer features precise dimensions (ID: 17mm, OD: 27.4mm, Thickness: 3.3-3.7mm) manufactured to DIN 127B standards for M16 screw applications. The zinc-plated steel construction achieves Rockwell C44 hardness for consistent spring performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and unrestricted use in industrial markets.
