Osg 1400112005 Thread Forming Tap 6-32 Unc Plug

Product Description

The OSG 1400112005 is a thread forming tap in the HY-PRO NRT series, designed for cold-forming internal threads without cutting or producing chips. Sized for 6-32 UNC right-hand threads, this plug-chamfer tap features a cobalt steel construction with a titanium nitride (TiN) coating for improved wear resistance and heat tolerance. At 2 inches overall length with a 0.141-inch shank diameter, it is built for through-hole threading applications in a wide range of metallic workpiece materials. Licensed trades and machining professionals use this tap in CNC, manual, and hand-tapping setups requiring precise H10 thread tolerance control.

This tap is suited for through-hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The plug chamfer with 4 to 4.5 chamfered threads makes it appropriate for starting in a pre-drilled hole and running through to full depth. It performs in production and maintenance environments where chip-free thread forming is preferred over cut-tapping, particularly in applications where thread strength and surface finish quality are priorities.

Key Features

• 6-32 UNC right-hand thread forming, plug chamfer with 4 to 4.5 chamfered threads
• Cobalt steel construction for elevated heat and wear resistance in tough alloys
• TiN coating extends tool life and reduces friction during forming
• H10 thread limit for consistent tolerance control in high-volume or precision applications
• Chip-free cold-forming process — no flutes, no chip evacuation concerns
• Through-hole threading application with 0.685-inch tapping depth

Compatibility

Designed for through-hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces. Material application codes P and N apply.

Installation Notes

Thread forming taps require a specific tap drill size matched to the desired thread form — verify the correct forming drill diameter for 6-32 UNC before machining. Adequate lubrication or cutting fluid is essential when cold-forming threads to prevent galling and extend tool life. Power down or disengage all spindle drives before changing or inspecting taps. Follow applicable shop safety procedures and manufacturer torque guidelines for the tapping fixture or tapping head in use.
