IF IT HAS TO BE MOVED, RAISED OR LOWERED

Skidmore Wilhelm's hydraulic tension calibrator, the industry standard since its inception in the 1950s, remains unmatched for testing high-strength bolts. Vital in steel buildings, bridges, and structures with fasteners in slip-critical joints, our units ensure pre-installation verification of bolt installation methods. Fabricators and erectors rely on our equipment to simulate bolted joints accurately. Four approved methods, including Turn of the Nut and Calibrated Torque Wrench, demand proof of achieved pretension in bolts. Our units accommodate various tools, from hand torque wrenches to hydraulic wrenches, ensuring safety and precision in bolt tensioning processes.=
