Osg 1400111500 Thread Forming Tap 6-32 Unc Plug Cobalt

Product Description

The OSG 1400111500 is a thread forming tap designed for right-hand, through-hole threading in a 6-32 UNC configuration. Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This plug chamfer tap features a 4 to 4.5 thread chamfer, a cobalt construction with a bright finish, and an H5 thread limit for Class 2B fit. It measures 2.0 inches overall length with a shank diameter of 0.141 inches. It is installed by tool and die makers, machinists, and maintenance technicians working with ferrous and non-ferrous metals.

This tap is suited for threading through-holes in production and maintenance environments. It performs in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel applications. The HY-PRO NRT series from OSG is designed for tapping in both P and N material application codes, covering a wide range of common shop metals. The plug chamfer makes it appropriate for through-hole work where the tap can run fully through the workpiece to complete thread engagement.

Key Features

• Thread forming design displaces material for chip-free threading and stronger thread form
• Cobalt construction provides increased heat and wear resistance for demanding materials including hardened steel and stainless steel
• Plug chamfer with 4 to 4.5 chamfered threads suits through-hole threading applications
• H5 thread limit with Class 2B fit for standard precision threading requirements
• Right-hand thread direction, 32 threads per inch, 6-32 UNC specification
• Bright finish with no coolant-through requirement for straightforward shop use

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 thread form with a Class 2B fit.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard tap wrench, tapping head, or CNC tapping cycle rated for the appropriate torque and feed. Secure the workpiece fully before tapping and verify the pilot hole diameter matches the recommended tap drill size for 6-32 UNC thread forming. Thread forming taps require a specific forming drill size that differs from cutting tap drill charts — consult OSG published data for the correct pre-drill diameter. Apply an appropriate tapping fluid for the workpiece material to extend tool life and maintain thread quality.
