Value Collection MSC-04462172 Hand Tap 3/8-16 Unc

Product Description

The VALUE COLLECTION MSC-04462172 is a 3/8-16 UNC bottoming hand tap made from high speed steel with a bright uncoated finish. It is designed for cutting internal threads in through-holes and blind holes where full thread depth to the bottom is required. With 4 straight flutes and a right-hand thread direction, this tap is suited for threading operations in steel, cast iron, aluminum, and similar materials. The overall length is 2-15/16 inches with a thread length of 1-1/4 inches. This tap is used by machinists, maintenance technicians, and trade professionals performing manual or hand-tapping operations on a bench or in the field.

This bottoming tap is intended for use as the final tap in a three-tap sequence, following a taper and plug tap, to bring threads to the full depth of a blind hole. It is appropriate for general-purpose threading tasks in fabrication shops, maintenance environments, and field repair work where 3/8-16 UNC internal threads are required. The H2 thread limit provides a controlled fit tolerance suitable for standard fastener engagement in most production and repair applications.

Key Features

• Bottoming chamfer for threading to the bottom of blind holes
• 3/8-16 UNC thread form with right-hand direction
• H2 thread limit for controlled tolerance and standard fastener fit
• 4-flute straight flute design for general-purpose hand tapping
• High speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish suitable for use with cutting fluid

Compatibility

Designed as a standard replacement or general-purpose hand tap for 3/8-16 UNC bottoming tap applications in manual tapping handles and tap wrenches.

Installation Notes

This tap is installed using a standard tap wrench or T-handle tap holder. Secure the workpiece before beginning and apply cutting fluid throughout the tapping operation to reduce heat and extend tool life. Use this bottoming tap only after a taper or plug tap has started the thread. Back the tap out periodically to break chips and prevent binding, especially in deeper holes.
