Professional Applications & Engineering Value
This M1.6 metric spring lock washer delivers critical vibration damping in precision assemblies where micro-fasteners must maintain clamping force. The 18-8 stainless steel construction provides excellent corrosion resistance for medical devices, electronics, and aerospace components exposed to moisture or chemicals. The dual-sided serration pattern creates positive mechanical locking by biting into both the fastener head and bearing surface, eliminating the need for additional thread-locking compounds. With its Rockwell C38 hardness rating, this washer maintains spring tension through thermal cycling and mechanical stress, making it ideal for vibration-resistant applications in robotics, instrumentation, and miniature mechanical systems where reliability is paramount.
Specification Summary & Compliance
Manufactured to precise metric dimensions: 0.067" internal diameter, 0.126" outer diameter, and 0.020" thickness. Features top and bottom serration for maximum locking effectiveness. Constructed from 18-8 stainless steel with Rockwell C38 hardness for consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial fastening applications.
