5. Features of High Strength T.C. (Tension Control) Bolts
T.C. bolts, improved type of heavy hexagonal structural bolts, were developed for more simplified bolt
fastening and more accurate performance and offer such excellent characteristics as shown below
because no fastening technique of high level is required :

(1) Controlled clamping force can be ensured.
(2) Completion of bolt fastening can be comfirmed by the shear-off of the notched end of the bolt.
(3) Fastening can easily be done by electric wrench.
(4) Noiseless installation and no need of wrench adjustment.
(5) The bolt does not rotate when fastening.
(6) No apprehension of bolts being left unfastened.
