Professional Applications & Engineering Value
This M5 split lock washer delivers critical engineering value through its high-hardness steel construction and DIN 127B standard compliance. The split lock design creates continuous spring pressure that counters vibrational loosening in machinery, automotive assemblies, and industrial equipment. The Rockwell C44 hardness rating ensures the washer maintains its locking force without deforming under repeated stress cycles. Precision metric dimensions (5.4mm ID, 9.2mm OD) provide exact fitment for M5 fasteners, eliminating play and ensuring uniform clamping force distribution. This vibration-resistant washer solves common industrial challenges of fastener failure in high-vibration environments, extending equipment service life while reducing maintenance frequency.
Specification Summary & Compliance
Manufactured to DIN 127B specifications with precise dimensional tolerances for metric applications. Features 5.4mm internal diameter, 9.2mm external diameter, and 1.1-1.3mm thickness range. Constructed from high-carbon steel with Rockwell C44 hardness for optimal spring performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across regulated industries including automotive, machinery, and electrical equipment manufacturing.
