Professional Applications & Engineering Value

This M7 split lock washer engineered to DIN 127B standards solves critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and electrical enclosures. The 18-8 stainless steel material maintains its spring properties and corrosion resistance even in harsh environments, while the precisely calculated 7.5mm inner diameter and 12.8mm outer diameter ensure optimal force distribution. The split lock design creates constant tension that counters rotational forces, making it ideal for vibration-resistant fastening in manufacturing equipment, transportation systems, and outdoor applications where environmental factors would compromise ordinary fasteners.

Specification Summary & Compliance

This split lock washer features precise metric dimensions with 7.5mm ID, 12.8mm OD, and 1.5-1.7mm thickness specifically designed for M7 screw sizes.
