Value Collection MSC-04475216 Tap Set 9/16-18 Unf 4 Flute Hss

Product Description

The VALUE COLLECTION MSC-04475216 is a 3-piece tap set designed for cutting 9/16-18 UNF internal threads in metal workpieces. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this set delivers consistent cutting performance across a range of ferrous and non-ferrous materials. The 4-flute geometry provides good chip evacuation and thread finish in through-hole and blind-hole applications. Each tap has an overall length of 3-19/32 inches and a thread length of 1-21/32 inches. The H3 thread limit tolerance makes this set well-suited for standard UNF thread fits. Machinists, tool-and-die makers, and maintenance technicians install this type of tap set using a standard tap handle or tapping head on manual or CNC equipment.

This tap set is intended for right-hand 9/16-18 UNF threading operations in production, repair, and maintenance environments. Typical applications include tapping threads in steel, aluminum, cast iron, and similar materials where a fine-pitch unified thread is required. The 3-piece set typically includes taper, plug, and bottoming taps, allowing the user to thread through-holes and blind holes to near full depth. It suits both shop floor machining and field maintenance scenarios where UNF fastener threads must be cut or restored.

Compatibility

Designed for cutting 9/16-18 UNF right-hand internal threads; suitable for use in standard tap handles, tap wrenches, and compatible tapping fixtures sized for this thread class.

Installation Notes

Tapping operations should be performed by qualified machinists or maintenance technicians familiar with thread-cutting procedures. Always apply an appropriate cutting fluid or tapping compound for the workpiece material to extend tap life and improve thread finish. Secure the workpiece firmly before tapping, and ensure the tap is started square to the hole to avoid tap breakage or cross-threading. Follow applicable shop safety practices and equipment manufacturer guidelines when using power tapping equipment.
