Value Collection MSC-04687109 Nut Tap 3/4-10 Unc Hss

Product Description

The VALUE COLLECTION MSC-04687109 is a 3/4-10 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 4-flute tap carries an H3 thread limit, making it well suited for general-purpose threading in steel, iron, and similar materials. The overall length is 9 inches with a thread length of 3.25 inches. Machinists and tool-and-die professionals install this tap using a standard tap wrench or machine spindle in drilling and tapping operations.

This nut tap is used in production and maintenance environments where 3/4-10 UNC internal threads are required in nuts, flanges, couplings, and similar components. The straight-flute, 4-flute geometry is appropriate for through-hole applications in short-chipping materials. It fits both hand-tapping and light machine-tapping setups. The 9-inch overall length provides clearance for stacking multiple nuts on the tap shank during nut-tapping operations, which is the primary advantage of a nut tap over a standard hand tap.

Key Features

• 3/4-10 UNC thread size with H3 thread limit for consistent fit tolerances
• High-speed steel construction provides good wear resistance across a range of workpiece materials
• 4-flute design for stable cutting action in through-hole and nut-tapping applications
• Bright finish — no coating — suited for use with cutting oils and general-purpose tapping fluids
• 9-inch overall length allows finished nuts to stack on the shank and clear during continuous nut-tapping
• 3.25-inch thread length accommodates the full thread engagement required for standard 3/4-10 nuts

Compatibility

Designed as an OEM-style replacement or direct-use nut tap for standard 3/4-10 UNC threading applications in production machining, maintenance, and tool-and-die environments.

Installation Notes

This tap is installed by a machinist or tooling professional using a tap wrench, tapping head, or machine spindle rated for the required torque. Always apply a suitable cutting fluid for the workpiece material to extend tool life and improve thread finish. Ensure the workpiece is securely fixtured and the starting hole is drilled to the correct tap drill diameter for 3/4-10 UNC before tapping. Inspect the tap for wear or chipping before each use and replace if cutting edges are damaged to avoid broken taps in the workpiece.
