GWY has been a global leader in bolt fastening tools since 1976. Our Turn of Nut series 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 standards of the federal government for structural fastening. Our other line of tools include the popular TC wrenches for shear bolts, and our torque wrenches for snug tightening, calibration, and other duties. We also offer 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.
