Klein Tools 3223 1-5/16-Inch Nominal OpeningStructural Connecting Spud Wrench

The Klein Tools 3223 is a heavy-duty industrial spud wrench built with a 1-5/16-inch nominal opening for high-torque fastening of 7/8-inch bolts and U.S. Regular series nuts during steel frame construction. Precision forged in the USA from heat-treated select alloy steel, this 17.375-inch overall length hand tool incorporates an extra-large hub head to sustain extreme leverage forces without fracturing. A continuous handle taper from 1-1/8 inches down to 9/32 inch enables ironworkers to align misaligned bolt holes without wedging, while a 60-degree offset head angle provides maximum hand clearance against structural I-beam flanges and connection plates.

Best Used For:

  • Structural Steel Frame Connecting: Fastening 7/8-inch structural bolts and U.S. Regular square or hex nuts on steel girders, trusses, and beam joints.
  • Bolt Hole Alignment: Inserting the 17.375-inch continuously tapered handle into overlapping steel plate openings to pry members into concentric alignment.
  • Heavy Industrial Frame Assembly: Torquing structural fasteners across commercial building construction, tower erection, and staging frameworks.

Key Performance & Safety Features

  • Forged US Select Alloy Steel: Premium heat-treated steel construction supplies maximum tensile strength under heavy leverage loads.
  • Extra-Large Hub Head Architecture: Reinforced head design provides superior structural integrity during high-torque turning operations.
  • Continuous Non-Binding Taper Handle: Gradual 1-1/8-inch to 9/32-inch handle taper slides smoothly into misaligned bolt holes to align multi-layer plates.
  • 60-Degree Offset Head Angle: Deep angle offset keeps hands and knuckles clear of beam flanges and obstruction plates.
  • Black Oxide Protective Surface: Corrosion-resistant coating with rust-preventative finish guards against jobsite moisture and chemical exposure.
  • Stamped Forging Identifiers: Stamped part number, bolt size, and opening dimensions provide quick on-site tool verification.

Pro-Tip: When positioning heavy structural steel members, insert the 9/32-inch tip of the tapered handle through misaligned bolt holes first to lever the plates into position. The 17.375-inch shaft gives ample mechanical leverage to bring holes into alignment before hand-threading 7/8-inch bolts into adjacent openings.
