Value Collection MSC-04477105 3/4-10 Unc Plug Tap Hss

Product Description

The VALUE COLLECTION MSC-04477105 is a straight flute plug tap designed for cutting 3/4-10 UNC internal threads in ferrous and non-ferrous materials. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable performance in general-purpose threading applications. It features 4 flutes and a plug chamfer, which distributes the cutting load across several leading threads for smooth entry and reduced torque. The overall length is 4.25 inches with a thread length of 2 inches. Right-hand thread direction matches standard UNC fastener orientation. H3 thread limit provides a controlled tolerance fit suitable for most standard threaded assemblies.

This tap is suited for use in machine shops, maintenance and repair operations, and production environments where 3/4-10 UNC threads are required. The plug chamfer style makes it appropriate for through-hole threading and for starting threads in blind holes where some lead-in room is available. It is used by machinists, maintenance technicians, and industrial tradespeople working with steel, cast iron, aluminum, and similar materials.

Key Features

• 3/4-10 UNC thread form for standard unified coarse-pitch applications
• 4-flute straight flute geometry for general-purpose machine and hand tapping
• Plug chamfer (3-5 thread lead) for balanced entry in through-hole and open blind-hole work
• High-speed steel construction for durability across a wide range of workpiece materials
• Bright, uncoated finish suitable for use with cutting fluid in standard threading operations
• H3 thread limit for consistent tolerance control in standard UNC assemblies
• Right-hand thread direction — compatible with standard UNC fastener systems

Compatibility

Designed as a standard replacement or service tap for any application requiring 3/4-10 UNC internal threads. Compatible with standard tap holders, collets, and tapping heads sized for 3/4-inch shank taps.

Installation Notes

Tapping operations should be performed by a qualified machinist or maintenance technician using the appropriate tapping fluid for the workpiece material. Secure the workpiece firmly before beginning and ensure the tap is aligned perpendicular to the hole to prevent tap breakage or thread distortion. Always relieve chip buildup by periodically reversing the tap, particularly in deeper holes. Disable and lock out any powered machine before changing or inspecting taps manually.
