Value Collection MSC-04438321 Straight Flute Tap 10-32 Unf

Product Description

The VALUE COLLECTION MSC-04438321 is a straight flute tap designed for cutting 10-32 UNF internal threads in through-holes and shallow blind holes. Manufactured from high-speed steel with a bright, uncoated finish, it delivers reliable performance in ferrous and non-ferrous materials. The plug chamfer features 3 to 5 lead threads, making it suitable as a starter tap or for threading through-holes in a single pass. With 4 flutes and an H3 thread limit, this tap holds close tolerances for a Class 2B fit. Overall length is 2.375 inches, and thread length is 0.875 inches. Sold individually.

This tap is used in general machining, maintenance, and fabrication applications where 10-32 UNF threads are required. The straight flute design is best suited for use in through-holes or short blind holes where chips can clear freely. It is appropriate for use in drill presses, CNC machining centers, tapping arms, and hand-tapping operations. Machinists, maintenance technicians, and tool and die workers commonly use this tap size for fastener threads in sheet metal, enclosures, electrical panels, and light structural components.

Key Features

• 10-32 UNF thread form for fine-pitch, high-strength thread applications
• High-speed steel construction provides durability across a range of workpiece materials
• Plug chamfer with 3 to 5 lead threads for versatile starting in through-holes
• 4 straight flutes for chip clearance in through-hole and shallow blind-hole applications
• H3 thread limit maintains Class 2B fit tolerances for standard fastener compatibility
• Bright, uncoated finish suitable for use with standard cutting fluids and tapping compounds

Compatibility

Designed as a standard replacement or stock tap for any application requiring 10-32 UNF internal threads with a Class 2B fit and H3 tolerance.

Installation Notes

Always secure the workpiece and use the correct tap drill size for 10-32 UNF threads before tapping. Apply a suitable tapping fluid or cutting compound to extend tool life and improve thread quality. Back the tap out periodically to break and clear chips, particularly in deeper holes. Inspect tap flutes and chamfer for wear or chipping before each use to avoid thread damage or tap breakage.
