• 1.5-1.7mm thickness range maintains proper deflection characteristics for effective locking action

Professional Applications & Engineering Value

These M5 split lock washers solve critical vibration-induced loosening problems in industrial assemblies. The zinc-plated steel construction provides dual protection - the spring steel core maintains constant tension while the zinc coating resists environmental corrosion. Engineered to DIN 7980 standards, these washers deliver predictable performance in automotive, machinery, and electrical equipment applications where thermal cycling and mechanical stresses compromise standard fasteners. The split lock design creates continuous opposing force that counters rotational movement, making them ideal for motors, pumps, and vibrating machinery where maintenance access is limited and reliability is paramount.

Specification Summary & Compliance

This metric split lock washer features precise dimensions (5.4mm ID, 8.8mm OD, 1.5-1.7mm thickness) manufactured to DIN 7980 specifications for dimensional accuracy and performance consistency. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications across international markets.
