HEICO-LOCK® REACTION WASHERS EFFECTIVE PROTECTION AGAINST SELF-LOOSENING OF LARGE BOLTED JOINTS Large bolted joints with a nominal size ≥ M24 (1”) can only be tightened by hand with great effort. The torque required to tighten the connection is simply too high, so electrically, pneumatically or hydraulically operated torque tools must be used. However, the use of a high-torque tool, which traditionally transfers the reaction torque that occurs when tightening via a supporting reaction arm, represents a major safety risk even for experienced operators. HEICO-LOCK® Reaction Washers enable safe...

DESIGN AND FUNCTION HEICO-LOCK® is a 2-washer locking system based on tension force, which prevents bolted joints from self-loosening according to the wedge locking principle. External radial ribs, which imprint into the bearing surface and into the bolt head and/ or nut along with the engaged internal wedges ensure that the required preload force is maintained under extreme operating conditions. The HEICO-LOCK® Reaction Washers are unique in their design and are characterized by a gear-shaped contour of the bottom washer. This contour, in combination with a special dual socket, enables tightening...
