Klein Tools Barrel Drift Pin 3261 13/16 Inch Diameter 8640 Alloy Steel Alignment Punch (8 Inch Length Drop Forged Black Rust Resistant Finish)

Klein Tools 3261 13/16-Inch Body Diameter 8640 Alloy Steel Barrel Drift Pin

The Klein Tools 3261 is a 13/16-inch (0.813") body diameter barrel-type drift pin engineered for structural hole alignment across heavy steel construction and rigging applications. Precision machined from drop-forged and heat-treated 8640 alloy steel, this 8.0-inch long, 13.6 oz alignment tool features a uniform dual-taper profile tapering down to a 7/16-inch (0.438") point diameter to smoothly center overlapping bolt holes in structural beam flanges, gusset plates, and heavy iron frameworks. Finished with a rust-resistant black coating, this heavy-duty steel erecting punch is designed to end-pein safely under sledgehammer strikes without fracturing or mushrooming prematurely on job sites.

Best Used For:

• Structural Steel Erection & Framing: Aligning misaligned bolt holes in heavy I-beams, steel trusses, and structural gusset plates prior to bolt installation.
• Bridge Construction & Heavy Ironwork: Driving through layered steel plates to bring multi-bolt connection joints into perfect concentric alignment.
• Heavy Equipment & Rigging Repair: Centering mounting bracket holes and heavy structural pins during industrial machinery assembly.

Key Performance & Safety Features

• Drop-Forged 8640 Alloy Steel: Heat-treated metallurgy provides high yield strength and impact resistance required for repeated sledgehammer striking.
• Dual Barrel Taper Design: Uniformly blended tapers transition smoothly from the 7/16-inch point to the 13/16-inch body diameter to quickly align stubborn bolt holes.
• Controlled End-Peining Metallurgy: Formulated to end-pein safely under impact, preventing metal flaking and premature mushrooming.
• Black Oxide Surface Finish: Protective coating guards against jobsite moisture, rust formation, and corrosion during outdoor exposure.
• Optimal Sizing & Striking Mass: Balanced 8.0-inch length and 13.6 oz weight supply high impact leverage while maintaining precise alignment control.

Technical Specifications

Pro-Tip: Always match your drift pin body size directly to the intended bolt hole diameter (13/16"). Insert the 7/16-inch point through misaligned steel plates first, then strike until the full 13/16-inch barrel passes through completely to establish a clear, unyielding pathway for structural bolts.
