Professional Applications & Engineering Value

These bronze external tooth lock washers deliver critical vibration resistance in demanding industrial applications where fastener security is paramount. The external tooth configuration creates multiple biting points that dig into both the bearing surface and fastener head, effectively resisting rotational forces and maintaining clamp load in high-vibration environments. Made from bronze material with Rockwell B60 hardness, these washers provide the ideal balance between strength and corrosion resistance, preventing galvanic corrosion when used with dissimilar metals. The ASME B18.21.1 compliance ensures dimensional consistency and reliable performance in machinery, electrical panels, and assembly applications requiring No. 10 screw security. Their environmentally compliant construction makes them suitable for global supply chains while delivering consistent locking performance that reduces maintenance frequency and equipment downtime.
