Tension Control Bolts and Shear Wrenches


Tension Control Bolts Ltd - designer, manufacturer and worldwide distributor of the most efficient High Strength Friction Grip/Pre-loaded bolting system.

Tension Control Bolts and the innovative Shear Wrench system are the lowest cost method of properly installing High Strength Friction Grip/Pre-loaded 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.

High strength TCBs 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 superior tensile strength together with phenomenal ductility result in a universal bolt that can be employed in almost all steelwork connections.

Efficient, safe, easy and quiet to install - TCBs are corrosion resistant and eco-friendly fasteners.
