Professional Applications & Engineering Value
These M3 split lock washers provide critical vibration-resistant fastening solutions for demanding industrial applications. The zinc-plated steel construction combines corrosion resistance with mechanical strength, making them ideal for automotive assemblies, machinery, and electrical enclosures where constant motion or thermal cycling can compromise standard fasteners. The split lock washer design creates continuous spring tension against both the bearing surface and fastener head, effectively preventing back-off in high-vibration environments. Engineered to DIN 7980 standards, these washers deliver predictable performance and dimensional consistency, reducing assembly time and maintenance requirements across production lines and equipment maintenance schedules.
Specification Summary & Compliance
This standard split lock washer features precise dimensions (3.4mm ID, 5.6mm OD, 0.9-1.1mm thickness) specifically designed for M3 screw applications. Manufactured from zinc-plated steel with Rockwell C44 hardness, the product complies with DIN 7980 specifications for dimensional accuracy and performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring suitability for global industrial markets with strict chemical substance restrictions.
