Value Collection JY4843322 Hand Tap 7/16-32 Uns Plug Hss

Product Description

The VALUE COLLECTION JY4843322 is a 7/16-32 straight-flute hand tap designed for cutting right-hand internal threads to the UNS thread standard. Built from high speed steel with a bright, uncoated finish, this tap handles the demands of manual threading in a wide range of metals and alloys. The plug chamfer, with its moderate lead-in length, makes it suitable for through-holes and deeper blind holes where a starting tap is not required. At 3-5/32 inches overall length, the tool fits standard tap handles used in bench and field work. The 4-flute design provides good chip clearance and cutting stability during hand tapping operations.

This tap is intended for threading operations performed by machinists, tool-and-die workers, maintenance technicians, and fabricators working on precision or general-purpose assemblies. The 7/16-32 UNS thread specification is a fine-pitch, unified national special thread, commonly found in instrument hardware, specialty fastener applications, and custom machined components where standard UNC or UNF pitches are not applicable. The H3 thread limit ensures consistent fit tolerance for Class 3B threaded holes.

Key Features

• 7/16-32 UNS thread specification for specialty fine-pitch applications
• High speed steel construction provides durability across a broad range of workpiece materials
• Bright, uncoated finish allows direct visual inspection of cutting edges before and after use
• Plug chamfer style suits through-holes and medium-depth blind holes
• 4-flute straight-flute geometry promotes stable cutting and controlled chip formation in hand tapping
• H3 thread limit and Class 3B fit deliver consistent, precision-tolerance internal threads

Compatibility

Designed as an OEM-style hand tap for use in standard tap handles compatible with 7/16-inch shank tooling where a 7/16-32 UNS internal thread is required.

Installation Notes

Hand taps should be installed and operated by qualified machinists or technicians familiar with manual threading procedures. Secure the workpiece before tapping and use a properly sized tap wrench to maintain alignment with the drilled hole. Apply cutting fluid appropriate to the workpiece material to reduce heat buildup and extend tool life. Back the tap out periodically to break chips and prevent tap breakage, particularly in deeper holes.
