Professional Applications & Engineering Value

This M4 conical spring lock washer delivers critical engineering value in applications where vibration-induced loosening compromises assembly integrity. The 18-8 stainless steel construction provides exceptional corrosion resistance, making it ideal for chemical processing, marine equipment, food machinery, and outdoor applications where moisture exposure is common. The conical spring lock washer design creates continuous spring tension that counters vibrational forces, thermal expansion, and material creep – common failure modes in dynamic industrial environments. Manufactured to DIN 6796 specifications, this precision metric lock washer ensures dimensional consistency for reliable performance in automated assembly systems and high-volume production environments where fastener failure can lead to costly downtime and safety concerns.

Specification Summary & Compliance

This spring lock washer features precise metric dimensions with 4.3mm inner diameter, 9mm outer diameter, and 1.3mm overall height, engineered for M4 screw applications. The component is manufactured in compliance with DIN 6796 standards for conical spring lock washers, ensuring dimensional accuracy and mechanical performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for use across regulated industries including electronics, automotive, and industrial equipment manufacturing.
