Value Collection JY4842365 Hand Tap 3/8-36 Uns Plug Rh

Product Description

The VALUE COLLECTION JY4842365 is a straight-flute hand tap designed for cutting right-hand internal threads in a 3/8-36 UNS thread form. Built from high speed steel with a bright, uncoated finish, this tap delivers consistent cutting performance across a range of workpiece materials. The plug chamfer — typically 3 to 5 threads of taper — makes it well suited for through-hole tapping applications where the tap can advance freely through the material. At 2-15/16 inches overall length, it fits standard tap wrench and T-handle setups used in machine shop and field maintenance work.

This tap is used in fabrication shops, maintenance and repair operations, and toolroom environments wherever a 3/8-36 UNS internal thread is required. The UNS thread standard covers unified national special thread forms not addressed by standard UNC or UNF series, making this tap the correct choice when thread pitch falls outside those common series. It is appropriate for both manual tapping by hand and guided tapping in drill press or mill setups at low speed. Machinists, maintenance technicians, and field service professionals are the typical users.

Key Features

• 3/8-36 UNS thread form — unified national special pitch for non-standard thread requirements
• Plug chamfer provides 3 to 5 threads of lead, optimized for through-hole applications
• High speed steel construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish — suitable for use with standard cutting fluids
• 4-flute straight flute geometry for clean thread cutting and chip evacuation in shorter-chipping materials
• Class 3B fit and H3 thread limit for close-tolerance internal thread production

Compatibility

Designed as an OEM-style replacement or direct-use hand tap for applications requiring a 3/8-36 UNS right-hand internal thread with a Class 3B fit and H3 thread limit.

Installation Notes

Always secure the workpiece firmly before tapping and align the tap perpendicular to the drilled hole to avoid cross-threading or tap breakage. Apply an appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Reverse the tap periodically during hand tapping to break chips and prevent binding. Replace worn or chipped taps before use — damaged high speed steel taps can seize and break inside the workpiece.
