Klein Tools Standard Bull Pin 3259TTS 1-5/16 Inch Diameter Stainless Steel Alignment Punch (12 Inch Length Tether Hole Slot Rust Proof Finish)

Klein Tools 3259TTS 1-5/16-Inch Diameter Stainless Steel Standard Bull Pin with Tether Hole

The Klein Tools 3259TTS is a 1-5/16-inch (1.313") body diameter stainless steel standard bull pin engineered for high-altitude structural steel alignment in marine, coastal, and highly corrosive environments. Precision machined and heat-treated from industrial stainless steel, this 12.0-inch long, 2.5 lb alignment punch features a gradual 7/16-inch (0.438") point taper, an integrated fall-protection tether hole, and a unique vertical slot designed to keep the pin hanging straight when tethered. Delivering total corrosion immunity without surface platings that can flake, this heavy-duty erecting punch brings misaligned bolt holes into concentric alignment across structural I-beams, steel plates, and offshore rigging frameworks.

Best Used For:

• Offshore & Coastal Ironwork: Aligning structural steel beam holes in saltwater or high-moisture marine environments without rusting or flaking plating.
• Elevated Structural Steel Construction: Connecting a fall-protection safety tether to the integrated hole while aligning beam flanges at elevated heights.
• Corrosive Industrial Assembly: Centering misaligned connection plates in chemical plants, wastewater facilities, and exposed outdoor steel structures.

Key Performance & Safety Features

• Solid Stainless Steel Construction: Heat-treated stainless steel metallurgy provides high tensile strength and maximum rust resistance.
• Integrated Fall-Protection Tether Hole: Machined attachment point enables ironworkers to tether the tool securely to prevent dropped-object hazards when working aloft.
• Vertical Alignment Tether Slot: Specialized slot geometry ensures the pin hangs straight down when attached to a lanyard for quick blind retrieval.
• Smooth Gradual Point Taper: Uniform transition from the 7/16-inch point to the 1-5/16-inch body diameter minimizes binding and hang-ups during extraction.
• Optimal Striking Mass: Balanced 12.0-inch total length and 2.5 lb weight supply maximum force transmission under heavy hammer blows.

Technical Specifications

Pro-Tip: When tethering this tool for work at height, pass your lanyard webbing through the integrated vertical slot. The specialized slot design forces the bull pin to hang straight down along your harness, preventing the long tapered shaft from catching on scaffolding or structural steel as you move.
