Value Collection JY4849238 Hand Tap 1-24 Uns Plug Rh

Product Description

The VALUE COLLECTION JY4849238 is a straight-flute hand tap designed for cutting 1-24 UNS internal threads in a wide range of materials. Built from high speed steel with a bright, uncoated finish, it delivers reliable performance in both production and maintenance threading applications. The plug chamfer — typically 3 to 5 threads — allows the tap to start easily in through-holes or sufficiently deep blind holes. With 4 flutes and a right-hand thread direction, this tap is suited for use with a standard tap wrench or adjustable tap holder. Overall length is 5.125 inches.

This hand tap is appropriate for use in general metalworking, machine shop, and maintenance environments where 1-24 UNS threaded holes are required. The UNS thread standard covers unified national special thread forms that fall outside the standard UNC and UNF series, making this tap a specific-purpose tool for non-standard thread pitches at the 1-inch nominal diameter. Typical users include machinists, millwrights, and maintenance technicians working on large fasteners, heavy equipment, or specialty assemblies.

Key Features

• 1-24 UNS thread form — unified national special pitch at 1-inch nominal diameter
• High speed steel construction for strength and wear resistance across a broad range of workpiece materials
• Bright, uncoated finish — suitable for use with cutting oil or tapping fluid
• Plug chamfer for easy entry into through-holes and deep blind holes
• 4-flute straight-flute geometry provides chip clearance and consistent thread form
• Class of fit 3B with H4 thread limit for close-tolerance internal thread applications

Compatibility

Designed as a hand tap for cutting 1-24 UNS right-hand internal threads to a 3B class of fit with H4 thread limit; verify workpiece material hardness and hole depth against the tap manufacturer recommendations before use.

Installation Notes

This tap is intended for use by qualified machinists or maintenance technicians with appropriate tapping equipment. Always apply a suitable cutting oil or tapping fluid before threading to extend tool life and improve thread quality. Secure the workpiece before starting and align the tap perpendicular to the hole to avoid tap breakage. Back the tap off periodically to break chips when threading deeper holes.
