Professional Applications & Engineering Value

This 18-8 stainless steel split lock washer delivers critical vibration resistance in demanding industrial applications where fastener security is paramount. The split lock washer design creates continuous spring tension that compensates for thermal expansion, material relaxation, and vibration-induced loosening. Engineered with Rockwell C35 hardness, it maintains its spring properties through repeated compression cycles, making it ideal for machinery, automotive assemblies, and electrical enclosures where No. 6 screw fastening requires reliable locking performance. The corrosion-resistant stainless steel composition ensures longevity in harsh environments, while the precise 0.148" ID x 0.25" OD dimensions provide optimal fit and function in inch-system applications.

Specification Summary & Compliance

This split lock washer features precise inch dimensions with 0.148" internal diameter and 0.25" outer diameter, specifically designed for No. 6 screw applications. Manufactured to ASME B18.21.1 standards, it ensures consistent performance and interchangeability. The washer is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and safety requirements for industrial components.
