Through Bolts are a single unit pre-assembled wedge type anchor, consisting of a nut, washer, threaded bolt with precision formed tapered mandril and a spring steel expansion collar.

Through Bolts provide a torque-controlled setting which when tightened draw the tapered mandril into the spring steel collar which generates controlled expansion against the walls of the hole.

Applications:

Heavy-duty torque controlled, deformation type stud bolt anchor specifically developed for through fastening into concrete.
