Professional Applications & Engineering Value
This Grade 8 split lock washer delivers exceptional engineering value in demanding applications where vibration-induced loosening compromises safety and performance. The zinc yellow-chromate plated steel construction combines corrosion resistance with the mechanical strength needed for heavy machinery, construction equipment, and industrial assembly lines. The split lock design creates continuous spring tension that counters rotational forces, maintaining clamp load in vibration-prone environments. With Rockwell C38 hardness, this washer withstands repeated loading cycles without losing its locking capability, making it ideal for critical connections in automotive, manufacturing, and structural applications where fastener reliability is paramount.
Specification Summary & Compliance
This standard split lock washer features precise dimensional specifications with 1.408" inner diameter, 2.301" outer diameter, and 0.422" thickness, engineered for 1-3/8" screw applications. Manufactured to ASME B18.21.1 standards for dimensional consistency and performance reliability. The product is fully REACH compliant (EC 1907/2006) as of June 14, 2023, meeting environmental safety requirements while delivering Grade 8 fastener strength for industrial-grade locking performance.
