Professional Applications & Engineering Value
This zinc-plated steel split lock washer delivers critical anti-loosening protection for machinery subjected to constant vibration and thermal cycling. The split lock design creates continuous spring tension against both the bolt head and mating surface, effectively resisting rotational forces that cause fastener failure. Engineered to DIN 7980 standards, this M18-compatible washer maintains precise dimensional stability in heavy-duty industrial applications including automotive assemblies, construction equipment, and manufacturing machinery. The zinc plating provides sacrificial corrosion protection, while the Rockwell C44 hardness ensures the locking teeth maintain their bite through repeated stress cycles, making it an essential component for mission-critical fastening systems.
Specification Summary & Compliance
This metric split lock washer features precise dimensions (19mm ID, 26.4mm OD, 3.3-3.7mm thickness) manufactured to DIN 7980 specifications for consistent performance. The product maintains Class 2A thread compatibility for M18 fasteners and demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for regulated industries and international supply chains.
