What are Tension Control Bolts?
Tension control bolts are heavy pre-assembled bolts used in steel frame construction.
The TCB was first introduced four decades ago by a Japanese bolt company. They have become increasingly popular and are quickly becoming accepted worldwide.
TC bolts require a special shear wrench designed specifically for installation. Features of the TC bolt include a pin tail that sheers off – ensuring dependable tension levels upon connection. These bolts are one of the most used fasteners for high strength applications.
It is important workers in the construction industry know how to effectively use TC bolts to ensure projects are successful.
Advantages of Tension Control Bolts
Installation is safe, fast, and easy
TC bolts are said to be easier to install than heavy hex bolts and other fasteners. The bolts only require one person for installation which reduces installation cost.
Provides consistent and reliable tension
Due to the heavy preload, the tension across the structure is evenly distributed, and there is no bolt relaxation because no torsional shear is induced during tightening
Single operator installation
This specific type of bolt can easily be installed by one person with prebuilt functionalities to determine the tensioning required to hold the structure together. This is easier to install and reduces cost.
Last longer than usual – guarantee the safety and longevity of your structures
Tension control bolts are engineered to provide structures with the highest longevity possible.
Less worker fatigue and resources required
These bolts are preloaded and involve light weight installation tools decreasing worker fatigue and ensuring no risk of HAVS (hand-arm vibration syndrome)
Eco friendly & long-term corrosion resistance
TC Bolts Ltd have developed their own innovative metal coating plant producing an environmentally friendly coating named Greenkote. Greenkote has excellent corrosion resistant properties and can be painted on without requiring any surface preparation.

Simple Visual Inspection for Quality Control
Once the spline (pin tail) has sheared off the correct tension has been achieved – this can be checked through a quick visual inspection, saving time and cost
Where can Tension Control Bolts Get Used?
Where should you store tension control bolts?
To reach the full benefit of your tension bolts it is vital the bolts are stored correctly. One way is storing them in an airtight container preventing from external effects such as humidity or very high temperatures.
Additionally, tension bolts should not be exposed to the environment for too long. Therefore, once you have opened the drum of bolts, you should seek to use them as soon as possible.
Always store in a cool and dry place – excessive exposure to moisture or high temperatures can affect the efficiency of the installation.
