Value Collection MSC-04428330 Hand Tap 10-32 Unf

Product Description

The VALUE COLLECTION MSC-04428330 is a 10-32 UNF bottoming hand tap machined from high speed steel with a bright uncoated finish. It carries a 4-flute straight flute design and a right-hand thread direction, making it suited for cutting internal threads to the bottom of a blind hole. The H2 thread limit and 3B class of fit meet standard tolerance requirements for unified fine thread fastener applications. Overall length is 2.375 inches with a thread length of 0.875 inches. Machinists, maintenance technicians, and tool-and-die professionals use this tap for hand tapping operations in steel, aluminum, and similar materials.

This tap is used in general metalworking, maintenance and repair operations, and production environments where a bottoming chamfer is required to thread close to the floor of a blind hole. The bottoming chamfer allows threading to within a few threads of the bottom, making it an appropriate finishing tap after a plug or taper tap has started the thread. It is well suited for both shop and field use wherever a 10-32 UNF internal thread is needed.

Key Features

• Bottoming chamfer allows threading to the base of blind holes
• 4-flute straight flute geometry for right-hand thread cutting
• High speed steel construction provides wear resistance across a range of workpiece materials
• Bright uncoated finish for use in standard tapping applications
• H2 thread limit and 3B class of fit for precise tolerance control
• No coolant-through requirement — suitable for hand tapping with standard cutting fluid

Compatibility

Designed as a standard replacement or stock hand tap for any application requiring a 10-32 UNF right-hand internal thread with a bottoming chamfer finish.

Installation Notes

This tap is intended for use by machinists or qualified technicians performing hand tapping operations. Secure the workpiece before tapping and use an appropriate cutting fluid to reduce friction and extend tap life. Apply steady, even pressure and back off periodically to break chips. Inspect the tap for wear or chipping before each use to avoid thread damage or breakage in the workpiece.
