Value Collection JY4841235 5/16-28 Hand Tap Hss Plug

Product Description

The VALUE COLLECTION JY4841235 is a 5/16-28 straight flute hand tap designed for cutting internal threads in a wide range of materials. Built from high speed steel (HSS) with a bright, uncoated finish, this tap holds up to the demands of general-purpose threading operations in shop, maintenance, and field environments. The plug chamfer style features a gradual lead-in that makes it well suited to threading through holes where starting alignment is straightforward. With a 3B class of fit and H3 thread limit, it produces threads to tight tolerance standards required for precision fastener engagement. Overall length is 2-23/32 inches.

This tap is used in metalworking and maintenance applications where a 5/16-28 UNS internal thread is required. The right-hand, 4-flute straight flute configuration works effectively in through-hole applications across steel, aluminum, brass, and similar machinable metals. It is a standard hand tap intended for use with a tap wrench or tap handle, making it practical for both bench work and on-site threading tasks performed by machinists, maintenance technicians, and trade professionals who require precise thread cutting without power tooling.

Key Features

• 5/16-28 UNS thread size for fine-pitch internal threading applications
• High speed steel construction provides durability across a broad range of machinable metals
• Plug chamfer with 4-flute straight flute design suits through-hole threading and easy starting
• 3B class of fit with H3 thread limit for precise, tolerance-controlled thread production
• Bright, uncoated finish for general-purpose use without coating-specific material restrictions
• Right-hand thread direction compatible with standard tap wrenches and handles

Compatibility

Designed as an OEM-style replacement or standard tooling option for applications requiring a 5/16-28 UNS internal thread produced with a plug chamfer hand tap.

Installation Notes

Use of this hand tap requires a properly sized tap wrench and a correctly sized and drilled pilot hole per UNS thread specifications for 5/16-28. Power down or secure any workpiece in a vise before tapping to prevent movement. Apply a suitable cutting fluid to extend tap life and improve thread finish. Do not force the tap if resistance increases — back off to break chips and clear the flutes before continuing.
