Professional Applications & Engineering Value
This Grade 8 split lock washer delivers critical vibration resistance in demanding industrial applications where fastener security is paramount. The zinc yellow-chromate plated steel construction provides dual protection against corrosion and wear, while the Rockwell C38 hardness ensures the washer maintains its spring properties under extreme pressure. Engineered to ASME B18.21.1 standards, this 7/8" split lock washer solves common industrial challenges in heavy machinery, construction equipment, and automotive assemblies where vibration-induced loosening can lead to equipment failure. The precise 0.894" ID and 1.459" OD dimensions guarantee proper fitment, while the split design creates continuous tension that compensates for thermal expansion and dynamic loading conditions.
Specification Summary & Compliance
This standard split lock washer features inch system dimensions (ID: 0.894", OD: 1.459", Thickness: 0.219") compatible with 7/8" fasteners. Manufactured from zinc yellow-chromate plated steel with Rockwell C38 hardness and Grade 8 strength classification. Fully compliant with ASME B18.21.1 mechanical specifications and REACH (EC 1907/2006) environmental standards, ensuring both performance reliability and regulatory adherence for industrial applications.
