Value Collection MSC-04682167 Nut Tap 3/8-16 Unc Hss

Product Description

The VALUE COLLECTION MSC-04682167 is a 3/8-16 UNC nut tap designed for threading through-holes in nuts and thin workpieces where the tap must pass completely through the material. Built from high-speed steel with a bright finish, this tap features 4 flutes and an H3 thread limit, making it suited for tapping standard unified coarse threads in a range of ferrous and non-ferrous metals. With a 6-inch overall length and a 2-inch thread length, it provides the reach and cutting surface needed for production threading operations on manual or CNC tapping equipment.

This nut tap is used in machining and fabrication environments where nuts or thin fasteners are threaded onto a continuous tap shank and ejected automatically. The long shank allows finished nuts to stack on the body during operation, increasing throughput in repetitive threading tasks. Typical applications include job shops, toolrooms, and light manufacturing settings where 3/8-16 UNC threaded fasteners are produced or reworked in volume. A licensed machinist or skilled tradesperson typically selects and operates this tooling.

Key Features

• 3/8-16 UNC thread form with H3 thread limit for controlled fit tolerance
• 4-flute geometry supports chip evacuation during through-hole tapping
• High-speed steel construction provides wear resistance across a broad range of workpiece materials
• Bright finish without coating — suitable for use with cutting fluids on a wide variety of metals
• 6-inch overall length allows stacking of multiple threaded nuts on the shank during operation
• 2-inch thread length delivers adequate cutting engagement for standard nut thicknesses

Compatibility

Designed as a standard replacement or supplemental nut tap for manual tapping handles, tapping heads, and CNC machines set up for 3/8-16 UNC thread production.

Installation Notes

Nut taps are installed and operated by machinists or toolroom technicians familiar with threading tooling and tapping equipment. Secure the tap firmly in a properly sized tap holder or chuck before use, and ensure the tapping machine or drill press is set to the correct RPM for the workpiece material and tap diameter. Apply appropriate cutting fluid throughout the operation to extend tool life and improve thread quality. Inspect the tap for chipping or wear regularly and replace it when thread quality degrades.
