Klein Tools Adjustable Spud Wrench 3239 1-5/8 Inch Capacity Construction Alignment Tool (16 Length Tether Hole Forged Black Oxide Steel)

Klein Tools 3239 1-5/8-Inch Capacity Adjustable Connecting Spud Wrench

The Klein Tools 3239 is an adjustable industrial spud wrench designed with an extra-wide 1-5/8-inch jaw capacity to accommodate heavy nuts and bolts up to 1 inch during structural steel assembly. Precision forged in the USA from 8640 select alloy steel, this 16-inch overall length hand tool incorporates hand-matched, precision-machined jaws with a smooth-turning knurl to eliminate the need for multiple fixed-size wrenches on site. A continuously tapered handle allows ironworkers to align misaligned bolt and rivet holes without binding, while an integrated lanyard tether hole supports fall-protection compliance when working at heights.

Best Used For:

• Variable Fastener Steel Connecting: Turning non-standard or multi-size structural nuts and bolts up to 1 inch across structural framing projects.
• Rivet & Bolt Hole Alignment: Inserting the 16-inch continuously tapered handle into overlapping steel connection plates to pry holes into alignment.
• Tethered High-Structure Construction: Operating safely on elevated staging and ironwork connections using a tether lanyard secured through the integrated tether hole.

Key Performance & Safety Features

• Forged US 8640 Alloy Steel: Heavy-duty heat-treated alloy steel body withstands high-leverage prying and heavy turning loads.
• Extra-Wide 1-5/8-Inch Jaw Opening: Oversized adjustable jaw capacity grips heavy structural nuts and bolts up to 1 inch in diameter.
• Hand-Matched Precision Jaws: Individually selected jaw components ensure tight tolerances and smooth knurl adjustment without binding.
• Continuous Non-Binding Taper Handle: Smoothly tapered shaft slides into misaligned bolt and rivet holes for rapid structural alignment.
• Integrated Fall-Protection Tether Hole: Built-in lanyard anchor point allows safe tethering using fall-prevention accessories.
• Black Oxide Industrial Finish: Protective corrosion-resistant surface treatment guards against jobsite moisture and rust.

Technical Specifications

Pro-Tip: Before applying heavy torque to a structural nut, adjust the knurl so the movable jaw fits snugly against the fastener flats with zero play. This prevents jaw spread and rounds off fastener edges under high leverage while using the 16-inch handle for maximum turning force.
