Tension Control Bolts (TCB) Installers

Site Service Engineering are recognised specialists in the installation of Tension Control Bolts.
                         
Tension Control Bolts or TCBs as they are commonly known throughout the industry, are replacing conventional high strength friction grip bolts and swaged collar rivets simply because they are very quick and easy to install using Lightweight Electric Shear Wrenches. Guaranteed tension together with visual inspection ensures engineers that connections are tightened in accordance with specifications.

Advantages of TCB’s           

• The lowest cost method for properly installed High Strength Friction Grip and pre-load bolts
• Quick, safe and easy to install
• Visual inspection
• Consistent Tension
• One man installation
• Non impacting electric shear wrenches
• No air compressors
• Reduced operator fatigue
• Reduced tool maintenance
• Low noise levels
• No torque wrenches required
• Tensile strength of a grade 10.9 bolt
• Ductility of a grade 8.8 bolt
• Higher grade steel facilitates the use of smaller diameter bolts
• TC Bolts are used in Shear and Tension
• No relaxation in the bolt since no torsional shear is introduced in its shank
• Will not loosen with vibration - no locknut required
• Sheared off spline is retained within the shear wrench to enable safe disposal

Applications

Site Service Engineering use Tension Control Bolts in a wide range of applications including:

• Highways Bridges
• Rivet Replacement
• Overhead crane structures
• Building Structures
• High Vibration Machinery
• Rail Joints
• Piling

The combination of superior tensile strength together with phenomenal ductility result in a universal bolt that can be employed in almost all steelwork connections.
