Klein Tools Standard Bull Pin 3265 1-1/4 Inch Diameter Heat Treated Alloy Steel Alignment Punch (12 Inch Length Forged Black Rust Resistant Finish)

Klein Tools 3265 1-1/4-Inch Body Diameter Heat-Treated Alloy Steel Standard Bull Pin

The Klein Tools 3265 is a 1-1/4-inch (1.25") body diameter standard bull pin engineered for economical structural hole alignment across commercial steel framing and ironwork applications. Machined and heat-treated from high-grade alloy steel, this 12.0-inch long, 2.5 lb alignment punch features a gradual 7/16-inch (0.438") point taper designed to smoothly align overlapping bolt holes in structural I-beams, heavy gusset plates, and steel truss assemblies. Protective black oxide coating guards the entire forged alloy body against jobsite rust, providing ironworkers and steel riggers with an economical, reliable striking pin for heavy structural assembly.

Best Used For:

• Commercial Steel Frame Erection: Driving through misaligned bolt holes in structural steel I-beams and connection plates to align holes prior to bolt installation.
• Bridge & Infrastructure Construction: Centering thick multi-layer structural steel joint plates using heavy sledgehammer impacts.
• Industrial Equipment Assembly: Aligning heavy machinery mounting bases and structural bracket holes during field maintenance and setup.

Key Performance & Safety Features

• Forged Heat-Treated Alloy Steel: Precision machined metallurgy provides optimal tensile strength and core durability under heavy hammer strikes.
• Gradual Point Taper Profile: Smooth transition from the 7/16-inch point to the 1-1/4-inch body diameter minimizes binding and hang-up during driving and extraction.
• Economical Standard Geometry: Classic straight pin design provides maximum economic value for daily structural steel alignment requirements.
• Black Oxide Surface Finish: Protective finish shields the forged steel shaft from atmospheric moisture and jobsite corrosion.
• Optimal Striking Balance: Full 12.0-inch total length and 2.5 lb weight deliver effective energy transfer while maintaining hand placement safety.

Technical Specifications

Pro-Tip: To remain strictly compliant with OSHA 1926.301(c) jobsite rules, frequently inspect the striking end of standard bull pins for any sign of metal mushrooming. Promptly dress and dress down any burred steel edges with a bench or angle grinder to maintain clear visibility and prevent dangerous metal chipping under sledgehammer impact.
