Professional Applications & Engineering Value
This Grade 8 split lock washer addresses critical vibration-induced fastener failure in heavy machinery, automotive assemblies, and structural applications. The zinc yellow-chromate plated steel construction combines corrosion protection with the mechanical strength needed for harsh operating environments. The split lock design creates continuous spring tension that compensates for thermal expansion, material relaxation, and impact loads. With Rockwell C38 hardness, these washers maintain their locking capability through extreme cycling conditions, making them ideal for industrial equipment maintenance, construction projects, and manufacturing applications where vibration resistance is paramount. The precise 3/8" sizing ensures compatibility with standard fasteners while providing reliable anti-rotation security.
Specification Summary & Compliance
This standard split lock washer features precise dimensions (0.385" ID × 0.68" OD × 0.094" thickness) engineered for 3/8" screw applications. Manufactured to ASME B18.21.1 specifications, it delivers consistent performance and dimensional accuracy. The product is fully REACH compliant (EC 1907/2006) with current SVHC documentation as of June 14, 2023, ensuring regulatory adherence for international industrial use. The Grade 8 classification confirms high tensile strength and reliability for demanding fastener applications.
