Klein Tools Barrel Drift Pin 3263 1-1/16 Inch Diameter 8640 Alloy Steel Alignment Punch (8 Inch Length Drop Forged Black Rust Resistant Finish)

Klein Tools 3263 1-1/16-Inch Body Diameter 8640 Alloy Steel Barrel Drift Pin

The Klein Tools 3263 is a 1-1/16-inch (1.063") body diameter barrel-type drift pin engineered for heavy-duty structural hole alignment across industrial steel construction, ironworking, and rigging setups. Precision machined from drop-forged and heat-treated 8640 alloy steel, this 8.0-inch long, 1.5 lb (24.0 oz) alignment tool features a uniform dual-taper profile tapering down to a 9/16-inch (0.563") point diameter to smoothly align overlapping bolt holes in structural I-beams, heavy gusset plates, and steel frameworks. Finished with a rust-resistant black oxide coating, this heavy-duty erecting punch is designed to end-pein safely under sledgehammer strikes without fracturing or mushrooming prematurely on job sites.

Best Used For:

• Heavy Structural Steel Erection: Aligning misaligned bolt holes in large I-beams, heavy steel trusses, and structural gusset plates prior to inserting 1-inch or 1-1/16-inch structural bolts.
• Bridge & Infrastructure Ironwork: Driving through thick multi-layered steel connection plates to bring heavy structural joints into exact concentric alignment.
• Industrial Machinery & Rigging Setup: Centering heavy mounting bracket holes and pin locations during industrial crane assembly and heavy equipment repair.

Key Performance & Safety Features

• Drop-Forged 8640 Alloy Steel: Heat-treated alloy steel construction delivers superior yield strength and impact resistance required for heavy sledgehammer striking.
• Dual Barrel Taper Geometry: Uniformly blended tapers transition smoothly from the 9/16-inch point to the 1-1/16-inch body diameter to quickly align stubborn bolt holes.
• Controlled End-Peining Metallurgy: Formulated to end-pein safely under heavy impact, preventing dangerous metal flaking and premature head mushrooming.
• Black Oxide Protective Coating: Corrosion-resistant finish guards against jobsite moisture, rust formation, and chemical wear during outdoor exposure.
• Substantial Striking Mass: Solid 8.0-inch overall length and 24.0 oz (1.5 lb) weight supply maximum impact energy while maintaining precise alignment control.

Technical Specifications

Pro-Tip: Always select a drift pin whose maximum body diameter matches the target bolt hole size (1-1/16"). Insert the 9/16-inch point through misaligned steel plates first, then strike with a heavy sledgehammer until the full 1-1/16-inch barrel passes completely through to establish an unyielding clearance path for structural bolts.
