Value Collection MSC-04473153 Straight Flute Tap 7/16-14

Product Description

The VALUE COLLECTION MSC-04473153 is a straight flute bottoming tap designed for cutting internal threads in pre-drilled holes where full thread depth is required close to the bottom. Manufactured from high-speed steel with a bright, uncoated finish, this tap produces a 7/16-14 UNC right-hand thread with a H3 thread limit tolerance. It features 4 straight flutes for efficient chip clearance in through-hole and blind-hole applications. The bottoming chamfer style allows threading nearly to the bottom of a blind hole, making it the appropriate choice when a plug or taper tap has already started the thread. Machinists and maintenance trades use this tap in manual and machine tapping operations.

This tap is suited for general-purpose threading in ferrous and non-ferrous metals, plastics, and similar materials in job shop, production, and maintenance-repair environments. The 7/16-14 UNC designation matches the coarse thread standard common in structural fastening, equipment frames, and general mechanical assemblies. With a thread length of 1.4375 inches and an overall length of approximately 3.16 inches, it fits standard tap wrenches and tapping heads without modification.

Key Features

• Bottoming chamfer for threading to the base of blind holes

Installation Notes

This tap is installed by machinists and maintenance technicians using a tap wrench or compatible tapping fixture. Always ensure the workpiece is securely clamped before tapping. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. A plug or taper tap should be used to start the thread before using this bottoming tap in a blind hole.
