Value Collection JY4876157 Hand Tap 1-5/8-16 Uns

Product Description

The VALUE COLLECTION JY4876157 is a 1-5/8-16 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 features a 6-flute straight flute geometry that provides clean chip evacuation in a range of materials. It is sized at 5 inches overall length, right-hand thread direction, Class 3B fit, and H4 thread limit. Machinists and toolroom technicians use this tap for precision threading operations that demand tight tolerance control.

This tap is suited for manual tapping operations in metalworking, toolroom, and maintenance environments. The bottoming chamfer style allows threads to be cut to the full depth of a blind hole, making it appropriate for applications where standard taper or plug taps cannot complete the thread. It is sized to the UNS 1-5/8-16 thread standard and is typically used in job shop, manufacturing, and industrial maintenance settings.

Key Features

• Bottoming chamfer geometry enables threading to the base of blind holes
• High speed steel construction provides durability across a range of workpiece materials
• 6-flute straight flute design supports efficient chip clearance during hand tapping
• H4 thread limit and Class 3B fit for controlled tolerance threading
• Bright uncoated finish suitable for use with standard cutting fluids
• Right-hand thread direction, 1-5/8-16 UNS thread form

Compatibility

Designed as an OEM-style hand tap for use in manual tapping operations requiring a 1-5/8-16 UNS bottoming tap with Class 3B fit and H4 thread limit.

Installation Notes

This tap is intended for use by machinists and toolroom professionals performing manual threading operations. Before tapping, ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for a 1-5/8-16 UNS thread. Apply appropriate cutting fluid throughout the operation and back off periodically to break chips. Do not exceed the rated torque capacity of the tap by applying excessive force, as breakage in the hole may result in a difficult extraction.
