Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this notched washer addresses critical challenges in machinery assembly and structural fastening. The iron construction with Rockwell B62 hardness provides exceptional resistance to deformation under sustained pressure, while the notched design prevents rotational slippage in high-vibration environments common in manufacturing equipment, construction machinery, and transportation systems. The precise 0.563" ID ensures perfect alignment with 1/2" screws, eliminating installation errors and reducing assembly time. With its substantial 2.5" OD and 0.25" thickness, this washer effectively distributes clamping forces across wider surfaces, preventing surface damage and maintaining joint integrity in heavy-load scenarios where standard washers would fail.

Specification Summary & Compliance

This precision notched washer features inch system measurements with 0.563" inner diameter, 2.5" outer diameter, and 0.25" thickness specifically engineered for 1/2" screw applications. Manufactured from iron material with Rockwell B62 hardness rating, it ensures consistent performance in demanding environments. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial components. Manufactured to precise dimensional tolerances suitable for Class 2A fitment requirements.
