Osg 1735801 Spiral Point Tap 6-32 Unc Plug H2 Hss

Product Description

The OSG 1735801 is a spiral point tap designed for cutting 6-32 UNC internal threads in a range of ferrous materials. It features a plug chamfer, 2 flutes, and a right-hand thread direction with an H2 thread limit and 3B class of fit. The tap is manufactured from vanadium high-speed steel (HSS-E) and finished with a steam oxide coating to improve lubricity and reduce galling during the tapping operation. Overall length is 2 inches with a thread length of 0.688 inches and a shank diameter of 0.141 inches. This tap belongs to OSG Series 300 and is sold individually.

This tap is suited for through-hole threading applications in residential and light industrial maintenance, fabrication shops, and production environments. The spiral point design pushes chips forward ahead of the tap, making it particularly effective in through-hole applications. Compatible materials include low-carbon steel, medium-carbon steel, hardened steel, and stainless steel. It is a standard choice for machine tapping operations where chip evacuation in through-holes is a priority.

Key Features

• 6-32 UNC thread form with 3B class of fit for standard tolerance threading
• H2 thread limit for consistent fit and dimensional accuracy
• Plug chamfer provides gradual thread engagement suitable for most through-hole work
• Vanadium high-speed steel (HSS-E) construction offers improved wear resistance over standard M2 HSS
• Steam oxide coating reduces friction and helps retain cutting fluid during operation
• Spiral point geometry pushes chips forward, minimizing chip packing in through-hole applications

Compatibility

Rated for use in low-carbon steel, medium-carbon steel, hardened steel, and stainless steel. Not intended for interrupted thread applications.

Installation Notes

This tap is intended for use by machinists and maintenance technicians operating drill presses, CNC machining centers, or hand tapping equipment. Always drill the correct tap drill size for 6-32 UNC and ensure the workpiece is securely fixtured before tapping. Apply appropriate cutting fluid for the workpiece material, especially when tapping stainless steel. Inspect the tap for wear or damage before each use and replace if chipping or dull cutting edges are observed.
