Value Collection JY4845160 Hand Tap 9/16-16 Uns Plug

Product Description

The VALUE COLLECTION JY4845160 is a 9/16-16 UNS straight-flute hand tap designed for cutting right-hand internal threads in a wide range of materials. Built from high speed steel with a bright uncoated finish, this tap features a plug chamfer with 4 flutes for efficient chip evacuation during hand-tapping operations. It carries a Class 3B fit and an H3 thread limit, making it suitable for applications requiring close-tolerance threaded holes. Overall length is 3-19/32 inches. Machinists, toolmakers, and maintenance technicians use this tap for tapping through-holes and blind holes where a standard entry chamfer is appropriate.

This tap is suited for general-purpose threading work in job shops, maintenance and repair operations, and manufacturing environments. The plug chamfer — typically 3 to 5 threads of taper — makes it a versatile starting choice for most through-hole tapping jobs and for continuing threads started with a taper tap in blind-hole applications. The UNS thread standard and 3B class of fit align with common fastener specifications found in industrial and mechanical assemblies.

Key Features

• 9/16-16 UNS thread form with right-hand cutting direction
• Class 3B fit and H3 thread limit for close-tolerance threading
• Plug chamfer provides versatile entry for through-holes and many blind-hole applications
• 4 straight flutes promote chip clearance during hand-tapping
• High speed steel construction offers good wear resistance across a broad range of work materials
• Bright uncoated finish — no additional coating to affect thread dimensions

Compatibility

Designed as a standard hand tap for use with tap wrenches and T-handle drivers that accept straight-shank taps in the 9/16-inch range. Suitable for threading UNS 9/16-16 holes in ferrous and non-ferrous materials in general machining and maintenance applications.

Installation Notes

This tap is intended for hand-tapping operations performed by machinists or qualified maintenance technicians. Before tapping, ensure the drilled hole is the correct tap-drill diameter for 9/16-16 UNS threads and that the workpiece is securely fixtured. Apply a suitable cutting fluid for the work material to extend tap life and improve thread finish. Back the tap off periodically to break chips, and never force a tap — excessive torque is the leading cause of breakage.
