Tension Control Bolts and the innovative Shear Wrench system are the lowest cost method for installing preloaded or High Strength Friction Grip (HSFG) bolts.

TCBs as they are commonly known throughout the world, are replacing conventional high strength friction grip bolts and swaged collar rivets simply because they are quick and easy to install using lightweight electric shear wrenches. Guaranteed tension together with visual inspection removes the likelihood of operator error and ensures engineers that connections are tightened in accordance with specifications.

Our System HRC structural bolting assemblies are used in a wide range of applications, from bridge splice plates to beam-to-column connections, from stadia roof trusses to rail switches and crossings. The combination of a TCBs superior tensile strength and phenomenal ductility result in a truly universal bolt that can be employed in almost all steelwork connections.
