Professional Applications & Engineering Value

This Acetal Plastic Spring Lock Washer delivers critical vibration damping in demanding applications where metal washers would corrode or conduct electricity. The spring lock mechanism maintains constant tension in assemblies subject to thermal cycling and mechanical stress, while the white Acetal material provides excellent resistance to chemicals, moisture, and wear. Engineers specify these washers for electrical enclosures, food processing equipment, and outdoor machinery where non-conductive, non-corrosive fastening solutions are essential. The dual 3/8" and M10 compatibility makes them ideal for global equipment manufacturers needing both inch and metric fastener systems.

Specification Summary & Compliance

Precision-engineered with 0.451" inner diameter and 0.848" outer diameter, this spring lock washer maintains consistent 0.05-0.06" thickness and 0.095" overall height. Manufactured from Acetal Plastic with Rockwell M80 hardness, it complies with RoHS 3 (2015/863/EU) environmental standards and operates reliably across -40°F to 212°F temperature ranges. The design ensures proper fit for both 3/8" and M10 screw applications in industrial assembly requirements.
