Professional Applications & Engineering Value
This bronze internal tooth lock washer provides critical vibration-resistant fastening in demanding applications where equipment reliability is paramount. The internal tooth location design creates multiple biting points that resist rotational forces and maintain clamp load in high-vibration environments such as motors, pumps, and heavy machinery. The bronze composition offers natural corrosion resistance without requiring additional plating, making these ASME B18.21.1 compliant washers ideal for electrical applications where galvanic corrosion must be avoided. With precise dimensions for No. 10 screw size applications, these washers deliver consistent performance in assembly operations while meeting stringent industry standards for quality and safety.
Specification Summary & Compliance
Manufactured to exact inch system dimensions: 0.195" ID, 0.381" OD, and 0.018-0.024" thickness range. Complies with ASME B18.21.1 standards for tooth lock washers, ensuring proper tooth configuration and performance characteristics. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for hazardous substance restrictions. The Rockwell B60 hardness provides optimal balance between strength and flexibility for reliable locking action.
