Value Collection MSC-04473237 Tap Set 7/16-20 Unf Hss

Product Description

The VALUE COLLECTION MSC-04473237 is a 3-piece tap set designed for cutting 7/16-20 UNF internal threads in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this set delivers consistent thread quality in production and maintenance applications. Each tap features a 4-flute geometry that promotes chip evacuation and maintains cutting accuracy through the full thread depth. The overall length of 3-5/32 inches and a thread length of 1-7/16 inches suit standard fastener thread depths in steel, aluminum, and similar machinable materials. Machinists, maintenance technicians, and tool-and-die professionals rely on this type of set for hand-tapping and machine-tapping operations alike.

This tap set is suited for right-hand threading operations in light manufacturing, repair shops, and field maintenance environments where 7/16-20 UNF threads are specified. The H3 thread limit designation makes these taps appropriate for use with standard UNF thread tolerances commonly called out in mechanical assemblies. A 3-piece set typically includes a taper, plug, and bottoming tap, allowing the user to start, advance, and finish threads in through-holes and blind holes without switching tool types.

Key Features

• High-speed steel construction provides hardness and heat resistance for threading steel and non-ferrous metals
• 4-flute design improves chip clearance and cutting stability during threading
• H3 thread limit suits standard UNF tolerance classes for general mechanical assembly
• Bright, uncoated finish allows visual inspection of cutting edge condition before and after use
• Right-hand thread direction matches the most common fastener specification in mechanical assemblies
• 3-piece set covers taper, plug, and bottoming tap applications in a single package

Compatibility

Designed for cutting 7/16-20 UNF right-hand internal threads in workpieces where an H3 thread limit is specified. Compatible with standard tap wrenches and tapping heads sized for 7/16-inch taps.

Installation Notes

Secure the workpiece firmly before beginning any threading operation. Use the appropriate cutting fluid or tapping oil for the base material to reduce friction and extend tap life. For hand tapping, advance with steady pressure and back off periodically to break chips, especially in blind holes. Follow applicable shop safety practices and OSHA general machine-guarding guidelines when operating power tapping equipment.
