Klein Tools Barrel Drift Pin 3260 11/16 Inch Diameter 8640 Alloy Steel Alignment Tool (7.5 Inch Length Drop Forged Black Rust Resistant Finish)

Klein Tools 3260 11/16-Inch Body Diameter 8640 Alloy Steel Barrel Drift Pin

The Klein Tools 3260 is an 11/16-inch (0.688") body diameter barrel-type drift pin engineered for precise structural hole alignment across heavy steel erection and rigging applications. Precision machined from drop-forged and heat-treated 8640 alloy steel, this 7.5-inch long, 9.6 oz alignment punch features a gradual dual-taper profile tapering down to a 5/16-inch (0.313") point diameter to smoothly line up overlapping bolt holes in structural beam flanges and gusset plates. Finished with a corrosion-resistant black oxide coating, this heavy-duty steel erecting tool is designed to end-pein safely under heavy hammer impact without mushrooming or fracturing prematurely during structural assembly.

Best Used For:

• Structural Steel Beam & Column Erection: Aligning misaligned bolt holes in structural steel I-beams, channel iron, and heavy gusset plates prior to inserting structural bolts.
• Heavy Equipment & Crane Maintenance: Driving through mounting bracket holes on industrial machinery to ensure precision pin alignment during field repairs.
• Ironwork & Metal Fabrication: Centering structural steel joints, bridge plates, and truss connections to allow effortless bolt insertion on job sites.

Key Performance & Safety Features

• Drop-Forged 8640 Alloy Steel: Heat-treated metallurgy delivers extreme yield strength and impact toughness required for heavy hammer striking.
• Dual Barrel Taper Design: Uniformly blended tapers gradually transition from the 5/16-inch point to the 11/16-inch body diameter to quickly align stubborn bolt holes.
• Controlled End-Peining Metallurgy: Formulated to end-pein safely under impact, preventing dangerous metal flaking or premature head mushrooming.
• Black Oxide Surface Finish: Protective coating guards against jobsite moisture, rust formation, and chemical corrosion during outdoor field exposure.
• Optimal Sizing & Leverage: Compact 7.5-inch overall length allows high strike accuracy in restricted spaces while delivering 9.6 oz of striking mass.

Technical Specifications

Pro-Tip: Always select a drift pin with a body diameter matching the bolt hole size (11/16") rather than forcing a larger diameter pin. Drive the narrow point through first to align the metal layers, then strike until the widest body section passes through to ensure smooth bolt clearance without damaging internal threads.
