Value Collection JY4847802 Hand Tap 13/16-16 Uns Hss

Product Description

The VALUE COLLECTION JY4847802 is a 13/16-16 UNS bottoming hand tap designed for cutting internal threads in through-holes and blind holes where threads must extend close to the bottom. Manufactured from high speed steel with a bright uncoated finish, this tap delivers durability across a wide range of ferrous and non-ferrous workpiece materials. The 4-flute straight flute geometry provides rigidity and good chip control during hand-tapping operations. At 4-15/32 inches overall length, it fits standard tap wrench chucks. The H4 thread limit and Class 3B fit designation make it appropriate for applications requiring close tolerance internal threading. Right-hand thread direction is standard for conventional fastener compatibility.

This tap is suited for tool and die, maintenance and repair, and general machining environments where a UNS 13/16-16 thread form is specified. The bottoming chamfer — typically 1 to 2 thread leads — allows threading to within a minimal distance of the hole bottom, making it the correct choice for blind-hole applications where plug or taper taps have already started the thread. It is used by machinists, millwrights, and maintenance technicians working in production and MRO settings.

Key Features

• Bottoming chamfer for threading close to the bottom of blind holes
• High speed steel construction for durability across a broad range of materials
• Bright uncoated finish — suitable for use with cutting oil or other tapping fluids
• 4-flute straight flute design provides rigidity and chip clearance during hand tapping
• H4 thread limit with Class 3B fit for close-tolerance internal threading
• Right-hand thread direction for standard fastener compatibility

Compatibility

Designed for hand-tapping applications requiring a 13/16-16 UNS thread form with a bottoming chamfer. Fits standard tap wrench chucks sized for the shank diameter of this tool class.

Installation Notes

This tap is intended for hand-tapping operations using a properly sized tap wrench — power driving without appropriate torque control is not recommended and may result in tap breakage. Ensure the workpiece is securely fixtured before beginning threading. Apply a suitable cutting fluid for the workpiece material to reduce friction and extend tool life. In blind-hole applications, clear chips frequently to prevent packing and tap breakage.
