Professional Applications & Engineering Value
This zinc-plated steel split lock washer delivers critical vibration resistance in demanding industrial applications where fastener security is paramount. Engineered to ASME B18.21.1 standards, the washer's split design creates continuous spring action that compensates for thermal expansion, vibration, and load variations in machinery, automotive, and construction equipment. The Rockwell C38 hardness ensures the washer maintains its tension properties under repeated stress cycles, while the zinc plating provides essential corrosion protection in harsh environments. Ideal for 3/4" screw applications requiring reliable locking performance, this heavy-duty component prevents costly downtime and maintenance by ensuring fastener integrity in critical assemblies.
Specification Summary & Compliance
This standard split lock washer features precise dimensions of 0.766" ID x 1.105" OD x 0.218" thickness, manufactured to ASME B18.21.1 specifications for inch system fasteners. The component maintains dimensional accuracy for proper fit and function with 3/4" screws. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability. The zinc-plated steel construction combined with Rockwell C38 hardness provides consistent performance meeting industrial locking washer requirements.
