Tension Control Fasteners

RotaBolt® fasteners, manufactued by James Walker RotaBolt, are modified bolts and studs that allow a specific tension to be applied. A finger-feel registering device - useable when wearing protective gloves or diving equipment - indicates achievement, maintenance or loss of the designed fastener tension.

The RotaBolt® range provides you with either finger-tip, visual or remote measurement of tension throughout the life of the bolted joint.

They surpass traditional tightening methods such as:

                 Hydraulic Tensioners


                 Torque Systems

which have severe control limitations and can result in unpredictable bolt tension and joint failure.

RotaBolts are setting new safety standards in a wide variety of sectors where joints are subject to fatigue, vibration, pressure containment and structural slippage.
