XXI
The World's most technologically advanced square drive tool.
 
The HYTORC XXI continuous rotation square drive Torque/Tension Bolting Machine is equipped with inter-changeable, interacting, coaxial driving and holding sockets for 360 degree tool fit.

The stationary tool stops the inner sleeve of the Clamp or the HYTORC DISC from turning when the nut is being turned at a known bearing face friction. The stationary bolt is elongated throughout its free length, literally hands free and to the desired load without torsion or side load. The lack of relaxation permits loads from 35% to 90% of yield, while standard length bolts are in order.
