Klein Tools Broad Head Bull Pin 3256TT 1-1/16 Inch Diameter Alloy Steel Alignment Punch (10 Inch Length Tether Hole Wrench Surfaces)

Klein Tools 3256TT 1-1/16-Inch Diameter Alloy Steel Broad-Head Bull Pin with Tether Hole

The Klein Tools 3256TT is a 1-1/16-inch (1.063") body diameter broad-head bull pin engineered for high-impact structural steel bolt hole alignment and ironwork assembly. Forged and heat-treated from heavy-duty alloy steel, this 10.0-inch long, 1.5 lb alignment punch features an enlarged angled striking head, squared wrench shoulders for releasing wedged pins, and an integrated tether hole for high-altitude fall protection compliance. Finished with a rust-resistant black oxide coating, this long-tapered ironworking tool minimizes binding and prevents chipping or head mushrooming while aligning heavy structural beam flanges and gusset plates.

Best Used For:

• Elevated Structural Ironwork: Fastening the pin to a safety tether lanyard while aligning structural steel I-beam holes at high elevation.
• Structural Steel Frame & Truss Erection: Driving the long 1/4-inch point through overlapping steel connection plates to bring bolt holes into exact alignment.
• Releasing Wedged Alignment Hardware: Applying an adjustable wrench across the forged squared shoulders beneath the broad head to twist out jammed pins effortlessly.

Key Performance & Safety Features

• Forged Broad Head Striking Surface: Enlarged angled head provides a wider target for sledgehammers, maximizing energy transfer while preventing chip hazards.
• Integrated Fall-Protection Tether Hole: Built-in head aperture allows ironworkers to secure the tool to a tether lanyard when working at heights.
• Forged Squared-Off Wrench Shoulders: Flat parallel surfaces below the head allow wrench application to loosen tightly bound or wedged alignment pins.
• Long Smooth Taper Profile: Gradual taper from the 1/4-inch point to the 1-1/16-inch body diameter prevents binding and binding-induced hang-ups during removal.
• Heat-Treated Alloy Steel & Black Finish: High-strength steel metallurgy resists mushrooming, cracking, and rust formation under repeated heavy sledgehammer strikes.

Technical Specifications

Pro-Tip: When working at heights, always thread your safety tether through the built-in head hole before driving the pin into steel joints. If the pin binds tight between heavy plates, place an adjustable wrench on the forged squared shoulders beneath the broad head to break it free cleanly without distorting the body.
