The HYTORC Reaction Washers eliminates the need for reaction arms, which are the most common cause of injury on bolting jobs. The unique design of the washer allows the dual socket driver to react on the washer while turning the nut.
The HYTORC Washer is manufactured in accordance with the requirements in the ASTM F3394/F3394M Standard Specification for Hardened Steel Backup and Reaction Washers. This standard covers general-purpose mechanical and structural use of washers with bolts, nuts, studs, Direct Tension Indicators and other threaded fasteners.
