Value Collection JY4840567 Straight Flute Tap 1/4-56 Uns

Product Description

The VALUE COLLECTION JY4840567 is a straight flute tap designed to cut 1/4-56 UNS internal threads in a plug chamfer configuration. Built from high-speed steel with a bright, uncoated finish, this tap is suited for threading ferrous and non-ferrous materials in machine shop, maintenance, and light manufacturing environments. It features four flutes and an H3 thread limit, producing a 3B class of fit for general-purpose threaded assemblies. Overall length is 2.5 inches. Machinists, toolmakers, and maintenance technicians install this tap in CNC machines, drill presses, or by hand with a standard tap wrench.

This tap is appropriate for through-hole and blind-hole applications where a plug chamfer entry angle provides a balance between starting ease and thread depth. The 1/4-56 UNS thread form is a unified national special designation used in applications requiring finer pitch than the standard UNF series at this diameter. Right-hand thread direction is standard. The bright finish means no coating is applied, making this a straightforward choice for general threading without additional surface treatment concerns.

Key Features

• 1/4-56 UNS thread form with right-hand direction for fine-pitch internal threading
• Plug chamfer style for balanced starting and threading performance in through and blind holes
• Four flutes provide good chip clearance in a compact cutting geometry
• H3 thread limit for consistent 3B class of fit in general-purpose assemblies
• High-speed steel construction for durability across a range of workpiece materials
• Bright, uncoated finish with no coolant-through requirement

Compatibility

Designed as an OEM-style replacement or direct-use tap for any application requiring 1/4-56 UNS plug-chamfer tapping with a 3B class of fit.

Installation Notes

Machinists and maintenance technicians should select a drill size appropriate for the 1/4-56 UNS thread form before use. Ensure the workpiece is properly fixtured and the tap is aligned perpendicular to the workpiece surface to prevent thread distortion or tap breakage. Use a compatible cutting fluid or tapping compound appropriate for the workpiece material. Inspect the tap for wear or damage before each use, and do not force the tap if resistance increases unexpectedly.
