Value Collection MSC-04463204 Hand Tap 7/16-20 Unf

Product Description

The VALUE COLLECTION MSC-04463204 is a 7/16-20 UNF straight flute hand tap designed for threading operations in a wide range of ferrous and non-ferrous materials. Built from high speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable cutting performance in manual and low-volume production tapping applications. It features a plug chamfer with 4 flutes and a right-hand thread direction, making it suitable for through-hole tapping where chip clearance is manageable. The overall length is 3-5/32 inches with a thread length of 1-7/16 inches. The H2 thread limit provides a close tolerance fit appropriate for standard UNF fastener assemblies.

This tap is suited for maintenance, repair, and fabrication work where 7/16-20 UNF internal threads are required. The plug chamfer style — with a moderate lead of 3 to 5 chamfered threads — makes it a practical choice for both through-holes and deeper blind holes where adequate chip evacuation can be maintained. Machinists, tool and die makers, and general fabricators will find this tap appropriate for hand tapping operations using a tap wrench or standard tapping fixture.

Key Features

• 7/16-20 UNF right-hand thread form for standard inch-series fine thread applications
• Plug chamfer provides a moderate lead-in for use in through-holes and suitable blind holes
• 4-flute straight flute geometry supports chip clearance in softer and medium-hardness materials
• High speed steel construction offers durability across a range of workpiece materials
• Bright, uncoated finish suitable for use with cutting oil or tapping fluid
• H2 thread limit ensures close tolerance compliance for standard UNF thread fits

Compatibility

Designed as a standard replacement or stock hand tap for 7/16-20 UNF threading applications. Compatible with standard tap wrenches and tapping handles sized for this shank diameter.

Installation Notes

This tap should be used with appropriate cutting fluid or tapping oil to extend tool life and produce clean thread form. Secure the workpiece before beginning the tapping operation and align the tap perpendicular to the hole to avoid thread damage or tap breakage. Back the tap off periodically to break and clear chips, especially in deeper holes. Installation is typically performed by machinists or maintenance technicians following standard hand tapping procedures.
