The lowest cost method for properly installed High Strength Friction Grip and pre-load bolts

Quick to Install

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 on-site/on-track noise levels

No torque wrenches required

Light weight wrenches of varying shapes and sizes

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
