Turn of Nut Wrenches, TC Wrenches, and Torque Wrenches for Absolute Accuracy
Since our beginning in 1975, GWY has been the global leader in providing quality wrenches for fastening bridges, buildings and industrial products. We specialize in the sales, rental and repair of installation tools for hex head and tension control bolts (TC bolts).
Since 2005, GWY has been an industry leader in providing high quality Turn of Nut (TN) wrenches. Turn of Nut is a standard for bridge and steel construction. Our TN Series wrenches use the “Angle of Rotation” method of tensioning bolt assemblies – rather than using torque.
To satisfy the requirements of hex head bolt users, Electric Torque Control Wrenches (STC Series & SR Series) and Torque Multipliers for standard Hex Head Bolts are also a part of our line of wrenches.
We have a large rental fleet of TC wrenches for all makes and sizes of TC Bolts. We also carry a large inventory of electric Torque Control (STC) Wrenches and Turn of Nut (TN) Wrenches in the rental fleet.
GWY has been a global leader in bolt fastening tools since 1975. Our Turn of Nut line of wrenches are custom designed in partnership with the global leader in electric tool companies, TONE. Using our years of experience in bolt fastening with TONE’s years of quality wrench manufacturing, we have created a wrench that meets the high state and federal standards for structural fastening. Our other lines of tools include the popular Shear wrenches for TC bolts, and our torque wrenches for snug tightening, and tensioning hex-head bolts. We also offer calibration repair services, rentals, and spare parts for all the wrenches we sell and some discontinued models. Our goal is absolute accuracy for any bolt fastening project.
