High Strength Tension Control Bolt (TC Bolt) is a pre-assembled fastener system consisting of a bolt, nut, and washer designed for structural steel connections. It ensures consistent clamping force through its unique design, where the notched tip shears off when the correct tension is achieved. TC bolts are easy to install using an electric shear wrench, offer quick and quiet operation, and eliminate the risk of under- or over-tightening—making them ideal for high-strength structural applications like bridges, buildings, and towers.
Improved type of Heavy Hexagonal Structural Bolts developed for simplified bolt fastening and more accurate performance. These bolts offer excellent characteristics as follows, without requiring high-level fastening techniques:
1. Controlled clamping force can be ensured.
2. Completion of bolt fastening can be confirmed by the shearing off of the notched end of the bolt.
3. Fastening can easily be done using an electric wrench.
4. Noiseless installation and no need for wrench adjustment.
5. The bolt does not rotate during fastening.
6. No risk of bolts being left unfastened.
