TC Bolts
TC Bolts
(OP)
General question - The wrench for tightening TC Bolts... The socket fits over the nut, and inside the socket is another that fits over the TC spline. The socket turns one way, but does the TC splice socket turn the other way, or does it remain stationarY?

The outer socket will rotate and tighten the nut untill the the bolt reaches the required tension. When the proper bolt tension is reached the outer socket will stop rotating and the inner socket will rotate in the oposite direction and shear the spline off.

RE: TC Bolts
I have used these fasteners in sizes ranging from 3/4 inch to 1 3/4 inch and the effort required to use the gun to tighten any of them was about the same (time to torque varies), very smooth, quiet and, efficient given proper preparation of the bolt patterns being tightened. The only real short-comeing with these bolts is the fact that all bolted pieces must be fairly open to allow access to the electric gun(some of which may have a socket that can be swiveled through 45 deg. or so, but there were no extensions or universal joints available at the time I retired). The primary reason for using this system is noise abatement and, to some degree to assure proper torque control( even though there are several cheaper alternatives available).

RE: TC Bolts
When the torque required to rotate the nuts exceeds the shear capacity of the groove at the end of the bolt, the tool will, in effect, twist the sline counter clockwise until it shears. In a properly designed bolt this happens without the bolt spinning.

The original question was "---does the TC splice socket turn the other way, or does it remain stationary?" To this my answer is directed.
