• Precision-engineered split design creates constant spring tension against the nut and bearing surface for reliable, reusable locking action.
• Full compliance with DIN 7980 standards ensures dimensional accuracy (10.7mm ID, 16mm OD, 2.3-2.7mm thickness) and consistent performance in metric M10 applications.
• RoHS 3 and REACH environmental compliance makes these washers suitable for regulated industries and global supply chains.
• Standard split lock configuration offers easy installation and removal while maintaining secure fastening in various mechanical systems.

Professional Applications & Engineering Value

These M10 metric split lock washers deliver critical engineering value by solving vibration-induced loosening in industrial machinery, automotive assemblies, and heavy equipment. The black-oxide steel material combined with Rockwell C44 hardness provides exceptional durability against wear and environmental exposure, while the precisely calibrated split design generates continuous radial pressure to maintain clamp load. This makes them ideal for vibration-resistant applications where safety and reliability are paramount, such as in motor mounts, conveyor systems, and structural frameworks. Their compliance with DIN 7980 ensures perfect compatibility with metric M10 fasteners, eliminating mismatches and reducing assembly errors in professional settings.

Specification Summary & Compliance

This split lock washer features precise metric dimensions: 10.7mm inner diameter, 16mm outer diameter, and 2.3-2.7mm thickness range, manufactured to DIN 7980 specifications for guaranteed interchangeability. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, confirming its suitability for environmentally conscious industrial applications worldwide. The black-oxide surface treatment on steel provides additional corrosion protection while maintaining the mechanical properties necessary for reliable locking performance in M10 fastener systems.
