Tension Control Bolts Cup Head
Tension Control Bolts and the innovative shear wrench system are the lowest cost method of properly installing high strength preloaded bolting assemblies. The standard TCB is recognisable due to the distinctive dome shaped head.
All Standard TCBs are:
- High strength structural bolting assemblies for preloading, System HRC
- Property class 10.9/10
- Manufactured in accordance with EN 14399-10
- CE and UKCA marked in accordance with EN 14399-1
- Supplied with superior corrosion protection Greenkote.
- Available in M12, M16, M20, M22, M24, M27, M30 & M36 diameters & multiple lengths.

TCBs as they are commonly known throughout the world, are replacing conventional high strength friction grip (HSFG) 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.
Wherever preloaded bolts are specified a TCB can be deployed to enjoy its many performance and installation advantages. System HRC TCBs can replace any hexagonal preload bolting assemblies - whether the HR or HV bolting system.
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, and easy install, TCBs are corrosion resistant and eco-friendly fasteners.
