Professional Applications & Engineering Value

These bronze split lock washers deliver critical engineering solutions where vibration-induced fastener failure is a primary concern. The bronze material offers natural lubricity and resistance to galvanic corrosion, making them perfect for electrical components, marine hardware, and chemical processing equipment where stainless steel fasteners might cause galling. The standard split lock washer type creates continuous spring tension against both the bearing surface and fastener head, maintaining clamp load under dynamic conditions. With precise inch measurement dimensions (0.094" ID, 0.172" OD, 0.020" thickness), they provide exact fitment for No. 2 screw applications in precision assemblies, eliminating the need for custom solutions and reducing installation time.

Specification Summary & Compliance

This split lock washer features dimensional specifications of 0.094" inner diameter, 0.172" outer diameter, and 0.020" thickness, engineered specifically for No. 2 screw size applications. Manufactured to exacting ASME B18.21.1 standards for standard type lock washers, ensuring consistent performance and dimensional accuracy. The bronze construction achieves Rockwell B90 hardness for optimal spring properties. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and suitability for restricted substance-sensitive applications.
