Professional Applications & Engineering Value
This 5/8" tension indicating washer is engineered to solve critical challenges in structural applications where precise bolt tension is mandatory. The orange tension-indicating dye provides a clear visual confirmation that the specified 19,000 lbs load capacity has been achieved, eliminating guesswork and preventing under or over-torquing. Made from high-strength steel with a Rockwell C37 hardness, it maintains integrity under extreme loads, making it ideal for bridges, heavy machinery, and steel frame constructions. Its compliance with ASTM F959 Type A325 and ASME B18.2.6 standards ensures it meets rigorous engineering requirements for safety and performance in industrial washers.
Specification Summary & Compliance
This washer features precise dimensions (ID: 0.657", OD: 1.323", Thickness: 0.126-0.133") for use with 5/8" screw sizes in the inch system. It conforms to ASME B18.2.6 and ASTM F959 Type A325 specifications, ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting sustainable and safe industrial use.
