Professional Applications & Engineering Value
Engineered for demanding industrial fastening applications, this M4 conical spring lock washer solves critical vibration-induced loosening problems in machinery, automotive, and electrical enclosures. The steel material and Rockwell C42 hardness provide exceptional springback characteristics that maintain clamping force despite thermal expansion and mechanical stress. The conical shape creates continuous axial pressure that compensates for settlement and wear, making it ideal for vibration-resistant assemblies where reliability is paramount. Meeting DIN 6796 specifications ensures consistent performance in metric fastener systems across European and international engineering projects.
Specification Summary & Compliance
This spring lock washer features precise metric dimensions (4.3mm ID × 9mm OD × 1.3mm height) manufactured to DIN 6796 standards for dimensional accuracy and mechanical properties. The Rockwell C42 hardness ensures optimal spring performance while the conical shape provides reliable locking action. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, this washer meets stringent environmental and safety requirements for industrial applications worldwide.
