Forged from select alloy steel, Klein Tools' 1-5/8-Inch Nominal Opening Spud Wrench is designed to withstand high-leverage and heavy loads. For use with 1-Inch bolts and U.S. heavy nut types, the extra heavy-duty head area provides maximum strength and durability. Plus, the continuous taper of the handle makes it easy to line up bolt holes. Includes a built-in hole so tool can be tethered when working at height.
