Professional Applications & Engineering Value
These split lock washers address critical vibration-induced loosening in industrial assemblies where 1/4" screws are subjected to constant motion or shock loads. The zinc-plated steel material provides essential corrosion protection while maintaining the Rockwell C38 hardness necessary for repeated compression cycles. The standard split design creates reliable spring action that compensates for thermal expansion and material settling, making these ASME B18.21.1 compliant washers ideal for machinery, automotive, and electrical enclosure applications where vibration resistance is paramount. The combination of precise dimensions (0.26" ID, 0.363" OD) and controlled hardness ensures consistent performance in industrial washers applications requiring dependable locking action.
Specification Summary & Compliance
This split lock washer features precise inch system dimensions with 0.26" internal diameter, 0.363" outer diameter, and 0.078" thickness, engineered for 1/4" screw size applications. Manufactured to ASME B18.21.1 specifications with Rockwell C38 hardness ensuring proper spring tension and durability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, meeting current regulatory requirements for hazardous substance restrictions.
