Value Collection JY4841482 Straight Flute Tap 5/16-48 Uns

Product Description

The VALUE COLLECTION JY4841482 is a straight flute tap designed to cut internal threads in a range of materials. Manufactured from high-speed steel with a bright/uncoated finish, it produces 5/16-48 UNS right-hand threads to a 3B class of fit with an H3 thread limit. The plug chamfer style makes it suitable for through-hole and most blind-hole threading applications. With 4 flutes and an overall length of 2-23/32 inches, this tap is a standard hand and machine tap used by machinists, maintenance technicians, and tool room professionals requiring precise UNS thread form production.

This tap is suited for threading operations in light to medium-duty machining environments including production shops, maintenance and repair facilities, and tool rooms. The 5/16-48 UNS thread specification serves specialty fastening applications where unified standard coarse and fine pitches are not appropriate. The plug chamfer provides a gradual thread lead-in, making it versatile across a wide range of workpiece materials typically encountered in precision machining and repair work.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using appropriate tapping fluid for the workpiece material. Secure the workpiece firmly before tapping and ensure the tap is started square to the hole to prevent thread misalignment or tap breakage. Disconnect or de-energize any machine before performing manual tapping operations on powered equipment. Follow applicable shop safety standards and machine tool codes when using this tap in a powered tapping setup.
