tubolt tcbThe TCB TuBolt is a non-preloaded blind fixing with all the simplicity, speed and QA of a standard TCB.

TCB Tubolts from Tension Control Bolts Ltd are:

  • Property class 10.9/10
  • 25mm diameter sleeve suitable for a 26mm clearance hole
  • Supplied as TCB TuBolt® assembly, comprised of 1x bolt, 1x sleeve, 1x nut and 1x washer
  • Quickly installated using a TCB shear wrench
  • Supplied with superior corrosion protection Greenkote®

TuBolts are designed to be used with standard 26mm diameter clearance holes in hollow or blind sections where there is no access to the other side of the steel.

They are installed using a TCB shear wrench with an M16 socket. The shear wrench turns the nut, therefore pulling the bolt into the sleeve. The tabs of the sleeve splay out for an interference fit.

As with standard TCBs, when the spline of the bolt shears off the TuBolt is fully installed. No calibrated torque tools are needed.

Though conceptually equivalent to some competitor’s products, TuBolts deliver superior performance and can be installed from any angle; there are no alignment requirements.
