Professional Applications & Engineering Value

This spring lock washer delivers critical vibration-resistant performance in demanding industrial applications where fastener loosening can compromise equipment safety and operational reliability. The zinc-plated steel construction provides essential corrosion protection for machinery exposed to moisture, chemicals, or outdoor elements. The top serration design creates positive mechanical locking by embedding into joint surfaces, making it ideal for high-vibration environments such as automotive assemblies, heavy machinery, electrical enclosures, and manufacturing equipment. Engineered to Rockwell C40 hardness, this washer maintains its spring properties through repeated loading cycles, ensuring long-term fastener integrity without deformation or loss of clamping force.

Specification Summary & Compliance

This No. 10 spring lock washer features precise inch system dimensions with 0.201" internal diameter, 0.481" outer diameter, and thickness range of 0.047-0.053". The washer maintains dimensional accuracy suitable for standard industrial applications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industries while meeting international compliance standards for hazardous substance restrictions.
