Professional Applications & Engineering Value

This split lock washer delivers critical engineering value by solving vibration-induced fastener failure in industrial equipment, machinery, and structural assemblies. The 18-8 stainless steel material provides exceptional corrosion resistance for harsh environments including chemical processing, marine applications, and outdoor installations. The standard split lock washer type creates continuous spring tension that compensates for thermal expansion and vibration, maintaining bolt preload in dynamic systems. With precise 0.26" ID and 0.487" OD dimensions specifically engineered for 1/4" screws, this component ensures proper fit and optimal locking force distribution. The combination of Rockwell C35 hardness and compliant spring design prevents permanent set while providing reliable, reusable locking performance across maintenance cycles.
