Value Collection JY4849329 Hand Tap 1-32 Uns Plug

Product Description

The VALUE COLLECTION JY4849329 is a straight-flute hand tap designed for cutting 1-32 UNS internal threads in a wide range of metalworking applications. Built from high speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable cutting performance in ferrous and non-ferrous materials. The plug chamfer — with approximately 3 to 5 chamfered threads — makes it well suited for through-hole tapping where a gradual thread lead-in is needed. With a 4-flute configuration and H4 thread limit, it holds consistent tolerances for Class 3B fits requiring tight dimensional control. Overall length is 5.125 inches.

This hand tap is intended for use in manual tapping operations on the shop floor, at a bench, or in light machine setups where a tap wrench or suitable holder is used. It addresses 1-32 UNS thread specifications commonly encountered in precision instrument work, miniature fastener applications, and fine-thread assemblies. The right-hand thread direction and straight flute geometry make it straightforward to use in most accessible hole orientations. Machinists, tool-and-die makers, and maintenance technicians are the typical end users of this tool.

Key Features

• High speed steel construction for durability across a range of workpiece materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• Plug chamfer for gradual thread engagement in through-hole tapping
• 4-flute straight flute design for balanced cutting action and chip control
• H4 thread limit maintains Class 3B fit tolerances for precision assemblies
• 1-32 UNS thread standard for fine-pitch, small-diameter threading requirements

Compatibility

Designed as an OEM-style hand tap for 1-32 UNS threaded holes requiring a Class 3B fit with an H4 thread limit, suitable for use with standard tap wrenches and manual tapping fixtures.

Installation Notes

Hand taps should be installed and operated by qualified machinists or maintenance technicians familiar with thread-cutting procedures. Always secure the workpiece firmly and apply an appropriate cutting fluid for the material being tapped. Use a calibrated tap wrench and advance the tap in short increments, backing off periodically to break chips and prevent binding. Inspect the tap for wear or damage before each use, as a damaged tap can seize in the hole and cause workpiece damage.
