Round Head Tension Control Bolts
Round Head Tension Control Bolts
Round head tension control bolts, commonly referred to as TC bolts, are essential in steel frame construction. These bolts come as a pre-assembled set consisting of a bolt, nut, and washer to connect structural steel components with precise and reliable torque, which is important in critical applications where the safety is dependent on the application’s integrity. To ensure the exact tension is achieved, the bolt features a spline that will break off under the specified torque during installation. This means it must be specially installed with a shear wrench. This unique tool applies simultaneous rotational forces, ensuring the nut is tightened clockwise to the exact required tension while the spline is rotated counterclockwise. Once the optimal tension is achieved, the spline breaks off, indicating a successful installation. This mechanism not only streamlines the installation process but also eliminates the guesswork in achieving the correct preload.
Round head tension control bolts are an ideal solution for applications requiring secure and precise steel-to-steel fastening, where consistent tension is essential. They are recognized by their domed head as opposed to a traditional hex head, because the bolt is not tightened from the head and therefore does not need to be grasped by a wrench. The bolts are particularly advantageous in scenarios where rapid assembly and consistent load distribution are crucial. However, it's essential to adhere to proper installation, storage, and handling practices to maintain the integrity of the pre-applied lubrication, which is vital for the bolt's performance and longevity.
- Efficient Installation: This bolt is installed with a specialized shear wrench that reduces labor and time.
- Precise Tension Control: Automatic tension calibration ensures optimal preload and structural integrity.
- Prepared For Use: Because these bolts are regulated, they are assembled by the manufacturer with the correct nut, washer, and lubrication, making the entire component ready to use as delivered.

Proper Storage for Tension Control Bolts
They must be stored away from outside elements to protect their pre-applied lubrication. Improper storage can lead to lubrication degradation, affecting the bolt's performance. Do not relubricate the bolts in the field; if the lubrication is compromised, the bolts must be discarded and replaced.
Tension Control Bolts Preparation
With tension control bolts, it is vital to use the entire component as it was prepared. The lubrication, nut, and washer are all designed to facilitate the bolt’s precise pre-calibrated torque; if the bolt is damaged or is not used as it was packaged, it will not perform as intended and the integrity of the application is at risk.
