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. FEATURES Fast and simple installation Minimum drill hole diameter. Drill hole diameter same as anchor diameter Ideal for through fastening. Supplied with nut and washer Reliable force-controlled setting High loading capacity. Follow up expansion with one-piece wedge mechanism Can be loaded immediately after installation
