Professional Applications & Engineering Value
This spring lock washer delivers critical vibration-damping performance for industrial assemblies where mechanical stability is paramount. Manufactured from 18-8 stainless steel, it provides exceptional corrosion resistance in demanding environments including marine, chemical processing, and outdoor applications. The precise 0.26" inner diameter ensures perfect compatibility with 1/4" screws, while the spring design maintains constant tension to prevent fastener back-off in high-vibration machinery, automotive systems, and heavy equipment. The Rockwell C38 hardness guarantees the washer retains its locking properties through repeated compression cycles, making it an essential component for maintenance-critical applications where reliability cannot be compromised.
Specification Summary & Compliance
This spring lock washer features inch system dimensions with 0.26" ID, 0.683" OD, and thickness range of 0.048-0.052". Manufactured to industrial standards for 1/4" screw applications, it maintains consistent performance with Rockwell C38 hardness rating. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for global industrial supply chains.
