Value Collection 314-9642 Tap Die Set 41 Pc Npt Unc Unf

Product Description

The VALUE COLLECTION 314-9642 is a 41-piece tap and die set designed for threading and re-threading operations across NPT, UNC, and UNF thread standards. Taps range from 1/8-27 to 3/4-16 and dies range from 1/4-20 to 3/4-16, covering the most common thread sizes encountered in plumbing, HVAC, and general mechanical work. All taps and dies are carbon steel with a bright finish. The set ships in a metal case and includes supporting tools for a complete threading setup without sourcing additional components.

This set is suited for shops, service vans, and job sites where technicians need to cut new threads or chase damaged threads on pipe fittings, fasteners, and mechanical components. The NPT coverage makes it directly applicable to plumbing and gas piping work where tapered pipe threads are standard. UNC and UNF coverage handles the fastener threading needs common in equipment installation and repair across HVAC, electrical, and mechanical trades.

Compatibility

Designed for use on standard NPT tapered pipe threads, UNC coarse-pitch fastener threads, and UNF fine-pitch fastener threads within the stated size ranges. Suitable for steel, iron, aluminum, and similar machinable materials commonly found in HVAC, plumbing, and mechanical assemblies.

Installation Notes

Tap and die work should be performed by a qualified tradesperson familiar with thread cutting procedures and applicable codes such as IFGC or IPC when threading pipe for gas or water service. Always use appropriate cutting oil to extend tool life and produce clean threads. Secure the workpiece firmly before cutting, and back the tap off periodically to clear chips. Inspect finished threads with a pitch gauge or test fitting before placing the joint in service.
