Value Collection MSC-04482162 Hand Tap 3/8-16 Unc

Product Description

The VALUE COLLECTION MSC-04482162 is a 3/8-16 UNC straight-flute hand tap designed for cutting right-hand internal threads in through-holes and blind holes. Built from high speed steel with a bright, uncoated finish, this plug-chamfer tap is suited for general-purpose threading in a wide range of ferrous and non-ferrous materials. It features four flutes for efficient chip evacuation and is ground to a 2B class of fit with an H5 thread limit, ensuring consistent dimensional accuracy across production and repair work. Overall length is 2-15/16 inches with a 1-1/4 inch thread length. It is used by machinists, maintenance technicians, and toolroom professionals for hand-tapping operations.

This tap is appropriate for use in job shops, maintenance and repair operations, and light manufacturing environments where 3/8-16 UNC threads are required. The plug chamfer, which incorporates a moderate lead-in of several threads, makes it well suited for starting a thread in a pre-drilled hole as well as continuing through a hole that has been started with a taper tap. It is commonly used on steel, aluminum, brass, and similar machinable materials in both bench-vise and drill-press tapping setups.

Key Features

• 3/8-16 UNC right-hand thread for standard inch-series fastener compatibility
• High speed steel construction provides wear resistance across a broad range of workpiece materials
• Bright uncoated finish suitable for general-purpose tapping with cutting fluid
• Plug chamfer provides a moderate lead-in, enabling use in both through-holes and deeper blind holes
• Four straight flutes promote chip clearance during hand-tapping operations
• H5 thread limit and 2B class of fit meet standard inch-series thread tolerance requirements

Compatibility

Designed as a standard 3/8-16 UNC plug hand tap suitable for use with conventional tap wrenches and T-handle tap holders sized for the tap's square drive.

Installation Notes

This tap is intended for use by machinists and maintenance technicians performing hand-tapping operations. Always drill to the correct tap drill diameter for 3/8-16 UNC threads before tapping, and ensure the workpiece is securely clamped. Apply an appropriate cutting fluid or tapping compound for the workpiece material to extend tap life and improve thread finish. Back the tap off periodically during cutting to break chips and reduce the risk of tap breakage.
