Value Collection JY4847893 Hand Tap 13/16-24 Uns

Product Description

The VALUE COLLECTION JY4847893 is a straight-flute hand tap designed for cutting internal threads in through-hole and bottoming applications. Built from high speed steel with a bright, uncoated finish, this tap produces 13/16-24 UNS right-hand threads to a Class 3B fit at H4 thread limit tolerance. The four-flute straight-flute geometry provides rigid chip control in a range of workpiece materials. Overall length is 4-15/32 inches, giving machinists and toolmakers adequate reach and leverage when driving by hand or with a tap wrench. This tap is suited for manual threading operations in maintenance, repair, and production machine shop environments.

This tap is intended for hand tapping operations where a bottoming chamfer is required to thread close to the bottom of a blind hole or to maximize thread engagement depth. The 13/16-24 UNS thread form is a Unified National Special designation, appropriate for applications where a non-standard thread pitch is specified by design or repair requirements. Machinists, maintenance technicians, and toolroom operators working in metalworking, industrial maintenance, and precision fabrication are the primary installers of this tap.

Key Features

• Bottoming chamfer allows threading to the bottom of blind holes with maximum thread depth
• 13/16-24 UNS thread form meets Unified National Special thread specifications
• High speed steel construction provides hardness and wear resistance across a broad range of workpiece materials
• Bright, uncoated finish suitable for general-purpose tapping with standard cutting fluids
• H4 thread limit with Class 3B fit for close-tolerance threaded connections
• Four-flute straight-flute design promotes rigidity and chip control in hand tapping

Compatibility

Designed as an OEM-style replacement or toolroom-stock hand tap for applications requiring a 13/16-24 UNS bottoming tap with a Class 3B fit and H4 thread limit tolerance.

Installation Notes

This tap is installed by machinists and toolroom technicians using a standard tap wrench or T-handle. Always use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Ensure the workpiece is securely fixtured and that the tap is started square to the hole before applying rotational force. Do not force a bottoming tap through an unprepared hole; always use plug or taper taps to progressively cut threads before finishing with this bottoming tap.
