Professional Applications & Engineering Value
This Grade 8 split lock washer delivers critical vibration-resistant performance in demanding industrial applications where fastener security is paramount. The zinc yellow-chromate plated steel construction combats corrosion in harsh operating environments, while the Rockwell C38 hardness ensures the washer maintains its spring tension and locking capability under heavy loads. Engineered specifically for 5/8" fastener systems, this split lock washer solves common industrial challenges including equipment vibration, thermal cycling, and dynamic loading conditions. The standard split design provides reliable spring action that compensates for material relaxation and maintains clamp load in heavy machinery, construction equipment, and automotive assemblies where vibration-induced loosening can lead to catastrophic failures.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications with 0.641" ID, 1.083" OD, and 0.156" thickness, engineered for 5/8" screw sizes in inch measurement systems. Manufactured to ASME B18.21.1 standards for dimensional accuracy and performance requirements, the washer maintains Grade 8 strength classification with Rockwell C38 hardness certification. Compliant with REACH regulations (EC 1907/2006) regarding substance restrictions and environmental safety standards, ensuring suitability for global industrial applications.
