Tension Control Bolts
The lowest cost method of properly installing high strength friction grip / preloaded bolts.
Tension Control Bolts are supplied with an environmentally friendly coating.
APPLICATIONS OF HIGH STRENGTH TENSION CONTROL BOLTS (TC BOLTS)
Motorway Bridges and Viaducts, Railtrack Connections and Joints, Railway Piling, Gantries,
Structural Steelwork,
Railway Bridges
TECHNICAL ADVANTAGES
- Consistent tension
- Visual inspection
- Higher grade steel and increased pre-load facilitates the use of smaller diameter bolts
- TCBs can be used in Shear and Tension
- No bolt relaxing since no torsional shear is induced during tightening
- Does not loosen with vibration - no locknut required
- Greenkote metal finish has a very hard surface and does not crack or flake
- Greenkote metal finish accepts paint without any preparation
COST SAVING
- Quick, safe and easy to install
- One man installation
- Reduced tool maintenance
- One tool can install several diameters
- Tools do not self destruct so last many years
- Greenkote metal finish requires no further treatment which means less time at site
SAFETY
- Non-impacting electric shear wrenches
- No risk of HAVS (hand-arm vibration syndrome)
- Reduced operator fatigue
- No air compressors with dangerous pipes & cables
- Low on-site noise - under HSE minimum levels
- No heavy calibrated torque wrenches required
- Ultra-light weight wrenches of varying shapes & sizes
- No acid required to etch bolts prior to painting due to special Greenkote metal finish

GREENKOTE - The ultimate anti-corrosion protection
| Greenkote is an innovative diffusion coating incorporating the very latest technology The patented
process is a Thermo-Chemical Surface Modification (TCSM) which can be applied to various metals,
alloys, sintered ferrous base materials, grey iron and cast iron. Unlike conventional coatings,
Greenkote is totally environmentally friendly and does not produce any solid, liquid or gaseous
toxic wastes. The process is also free of chrome, cadmium, acids, cyanides and chlorides. | |
