Osg 1400111605 Thread Forming Tap 6-32 Unc Plug

Product Description

The OSG 1400111605 is a thread forming tap in the HY-PRO NRT series, designed for cold-forming internal threads without cutting or producing chips. Built from cobalt high-speed steel with a TiN coating, this tap handles the stresses of forming threads in tough materials while extending tool life between changes. It carries a plug chamfer with 4 to 4.5 chamfered threads, a thread limit of H6, and an overall length of 2 inches. Licensed trades and precision machinists rely on this style of tap where chip-free threading is required in blind or through-hole applications.

This tap is suited for through-hole threading operations in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The 6-32 UNC thread size places it firmly in light fastener and instrument-grade work common in fabrication, maintenance, and OEM assembly environments. The right-hand thread direction is standard for the majority of production and repair threading setups.

Key Features

• Cobalt construction for heat and wear resistance in hard and abrasive materials
• TiN coating reduces friction and extends tool life
• Plug chamfer with 4 to 4.5 chamfered threads for guided entry in through-hole work
• H6 thread limit for consistent fit in standard 6-32 UNC threaded assemblies
• Chip-free cold-forming action eliminates chip clearance concerns in blind holes
• No coolant-through requirement simplifies setup on standard equipment

Compatibility

Designed for through-hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring a 6-32 UNC right-hand internal thread.

Installation Notes

This tap is installed by machinists or maintenance technicians using a standard tap wrench, tapping head, or CNC tapping cycle set for right-hand rotation. Ensure the pilot hole is drilled to the correct minor diameter for thread forming before tapping. Use a thread forming lubricant or cutting fluid appropriate for the workpiece material to reduce torque and protect the tap. Do not reverse the tap abruptly in hardened or stainless materials, as this can fracture the tool.
