Professional Applications & Engineering Value
This split lock washer delivers critical engineering value in applications where vibration-induced fastener failure poses significant operational risks. The zinc-plated steel construction combines corrosion resistance with mechanical strength, while the precisely engineered split lock design creates continuous spring tension that counters rotational forces. Engineered to ASME B18.21.1 standards, this washer maintains consistent performance in demanding environments including heavy machinery, automotive assemblies, and electrical enclosures where No. 8 screw fastening requires reliable vibration resistance. The Rockwell C38 hardness ensures the washer maintains its spring properties through repeated thermal cycles and mechanical stress, providing long-term locking security.
Specification Summary & Compliance
This split lock washer features precision dimensions of 0.174" ID, 0.293" OD, and 0.040" thickness, manufactured to ASME B18.21.1 specifications for dimensional accuracy and performance. The product maintains Rockwell C38 hardness for consistent spring tension and meets comprehensive regulatory requirements including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with current SVHC documentation. Designed specifically for No. 8 screw size applications in inch measurement systems.
