Osg 1737301 Spiral Point Tap 10-32 Unf 3 Flute Plug

Product Description

The OSG 1737301 is a spiral point plug tap designed for cutting 10-32 UNF threads in a variety of steel materials. Built from vanadium high speed steel (HSS-E) with a steam oxide coating, this tap handles hardened steel, low-carbon steel, medium-carbon steel, and stainless steel without the need for coolant-through capability. The 3-flute spiral point geometry pushes chips forward ahead of the tap, reducing clogging in through-hole applications. With an H5 thread limit and right-hand thread direction, it meets standard fitment tolerances for precision threaded assemblies. Overall length is 2.374 inches and thread length is 0.5 inches.

This tap is suited for production and maintenance environments where 10-32 UNF threaded holes are required in steel workpieces. Typical applications include fabrication shops, machine shops, and field maintenance operations working with electrical enclosures, instrument panels, and mechanical assemblies. The plug chamfer style - typically 3 to 5 lead threads - makes it the standard choice for through-hole tapping where thread cutting begins with moderate entry resistance.

Key Features

• 10-32 UNF thread form with right-hand cutting direction
• 3-flute spiral point design pushes chips forward for cleaner through-hole threading
• Vanadium high speed steel (HSS-E) construction for extended tool life in steel materials
• Steam oxide coating reduces friction and improves chip flow
• H5 thread limit for consistent tolerance control in precision applications
• No coolant-through requirement - suitable for standard dry or flood-lubricated setups

Compatibility

Designed for tapping 10-32 UNF threaded holes in hardened steel, low-carbon steel, medium-carbon steel, and stainless steel workpieces. Not intended for non-ferrous materials such as aluminum or brass without confirming suitability.

Installation Notes

This tap is installed by machinists and maintenance technicians using a tap wrench, tapping head, or CNC spindle depending on the application. Ensure the workpiece is securely fixtured before beginning the threading operation. Use an appropriate tapping fluid or cutting oil for stainless and hardened steel to extend tool life and maintain thread quality. Oversize thread profile is confirmed for this tap - verify H5 tolerance is acceptable for the mating fastener before use.
