Value Collection JY4842324 Straight Flute Tap 3/8-32 Unef

Product Description

The VALUE COLLECTION JY4842324 is a straight flute plug tap designed for cutting 3/8-32 UNEF right-hand internal threads in through-holes and blind holes with adequate chip clearance. Manufactured from high-speed steel with a bright, uncoated finish, this tap delivers reliable performance across ferrous and non-ferrous materials. The plug chamfer, ground on the first 3 to 5 threads, provides a moderate lead-in that suits most general-purpose tapping applications. With 4 flutes and an H3 thread limit, it holds tight tolerances suitable for standard fastener fits. Overall length is 2-15/16 inches and the tap weighs approximately 0.17 pounds.

This tap is suited for machine shops, maintenance facilities, and production environments where 3/8-32 UNEF threads are required. UNEF series threads are commonly used in precision assemblies, optical equipment, and thin-walled components where a finer pitch is needed than the standard UNF series provides. The right-hand thread direction is compatible with conventional tapping heads, CNC machining centers, and manual tap handles. This is a single-tap solution for shops that require an individual replacement or supplemental tap without purchasing a full set.

Key Features

• 3/8-32 UNEF thread form with right-hand thread direction
• Plug chamfer (approximately 3 to 5 threads) for general-purpose through-hole and blind-hole tapping
• High-speed steel construction for durability across a range of workpiece materials
• 4 straight flutes for chip evacuation in standard tapping operations
• H3 thread limit for consistent thread tolerance in standard fastener fits
• Bright, uncoated finish — suitable for use with cutting fluids of choice

Compatibility

Designed as an OEM-style replacement or direct-use tap for any application requiring a 3/8-32 UNEF straight flute plug tap in high-speed steel.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians using a standard tap handle, tapping head, or CNC spindle with appropriate tap chuck. Always apply cutting fluid suited to the workpiece material and ensure the workpiece is securely fixtured before tapping. Coolant-through is not supported on this tap. Follow all shop safety protocols when operating tapping equipment, including securing loose clothing and using eye protection.
