(TCB BOLT) TENSION CONTROL BOLT
TCB Bolt (Tension Control Bolt) and the innovative Shear Wrench system are the lowest cost method of properly installing pre-loaded 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 swagged 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.
Greenkote® anti-corrosion protection
Tension Control Bolts Ltd has its own metal coating plant producing an environmentally friendly process called Greenkote® which is comparable to galvanizing, although it is harder wearing and readily accepts all paint systems.
Greenkote is an advanced thermal diffusion coating of Zn-Al poly-metallic composition. The patented process takes basic thermal diffusion to the next level of quality and durability.
The coating is a technically superior replacement for zinc plating, hot dip galvanizing, mechanical galvanizing and zinc flake dip-spin. Greenkote delivers exceptional protection against corrosion and provides superior adhesion, coating uniformity, is hard wearing and completely eliminates hydrogen embrittlement issues.
The Greenkote processes is completely eco-friendly and does not produce any toxics or pollutants, including heavy metals and Cr6+.
