Tension Control Bolts

Tension control fasteneing system is a 3 piece fastening assembly with a 12-point spline, a high strength heavy hex nut, and a hardened flat washer. When installed with a dual socket electric wrench, the outer socket applies the turning force to the nut, while the inner socket holds the bolt in place by gripping the 12-point spline. When the forces reach the designated torque coefficient, the 12-point spline will shear off, leaving the bolt and nut securing the application at the proper tension.
