Klein Tools Broad Head Bull Pin 3255TT 1-1/4 Inch Diameter Alloy Steel Alignment Punch (13.75 Inch Length Tether Hole Wrench Surfaces)

Klein Tools 3255TT 1-1/4-Inch Diameter Alloy Steel Broad-Head Bull Pin with Tether Hole

The Klein Tools 3255TT is a 1-1/14-inch (1.25") 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 13.75-inch long, 2.8 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:

• High-Altitude Structural Ironwork: Securing the tool via a fall-protection tether while aligning misaligned structural steel beam holes at elevated heights.
• Heavy Steel Frame & Bridge Erection: Driving the long 5/16-inch point through multi-layered steel connection plates to bring bolt holes into concentric alignment.
• Releasing Wedged Alignment Hardware: Applying an adjustable wrench across the forged squared-off shoulders below the head to twist out stuck pins effortlessly.

Key Performance & Safety Features

• Forged Broad Head Striking Surface: Enlarged angled head provides a wider target for sledgehammers, increasing force transfer while reducing chip hazards.
• Integrated Fall-Protection Tether Hole: Dedicated attachment point allows structural ironworkers to tether the tool securely when working at heights.
• Forged Squared-Off Wrench Shoulders: Flat parallel surfaces beneath the head allow wrench application to twist out pinned or tightly bound alignment punches.
• Long Smooth Taper Profile: Gradual blending from the 5/16-inch point to the 1-1/4-inch body diameter prevents binding and binding-induced hang-ups during extraction.
• Heat-Treated Alloy Steel & Black Oxide Finish: High-strength metallurgy resists mushrooming and corrosion under repeated heavy jobsite impacts.

Technical Specifications

Pro-Tip: If a bull pin gets tightly bound between heavy steel plates during driving, do not strike the side of the shaft to loosen it. Instead, attach an adjustable wrench directly to the forged squared shoulders beneath the broad head and twist while pulling upward to free the tool safely without distorting the shaft.
