Osg 1062800 Straight Flute Tap 6-32 Unc Plug Hss

Product Description

The OSG 1062800 is a straight flute plug tap designed for cutting 6-32 UNC internal threads in a wide range of metals. It features 2 flutes, a plug chamfer for gradual thread engagement, and a bright uncoated high-speed steel construction. With a 2-inch overall length and an 11/16-inch thread length, this tap is suited for through-hole and shallow blind-hole applications where chip evacuation is managed manually or with coolant flushing. The H1 thread limit provides close tolerance control for standard UNC thread fits. Installed by machinists and trade professionals working in fabrication, maintenance, and mechanical assembly environments.

This tap is appropriate for use in ferrous and non-ferrous materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. It is commonly used in light manufacturing, HVAC equipment fabrication, electrical panel assembly, and general mechanical repair where 6-32 UNC threaded fastener holes are required. The straight flute geometry performs best in through-holes or when chips can be cleared between passes in blind holes.

• Compact geometry: 2-inch overall length, 11/16-inch thread length, 0.141-inch shank diameter

Compatibility

Designed for tapping 6-32 UNC threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces.

Installation Notes

Tapping should be performed by a machinist or qualified trade professional using a properly sized tap wrench, tapping fixture, or machine tool set to appropriate feed and speed for the workpiece material. Cutting fluid or tapping compound should be applied to extend tool life and improve thread quality in steel and cast iron. Back the tap out periodically to break and clear chips, especially in blind holes. Inspect thread fit with a 6-32 UNC go/no-go gauge after tapping to verify tolerance compliance.
