Value Collection MSC-04460234 Tap Set 1/4-20 Unc 3 Piece

Product Description

The VALUE COLLECTION MSC-04460234 is a 3-piece tap set designed for cutting 1/4-20 UNC internal threads in ferrous and non-ferrous metals. Each tap is ground from high-speed steel (HSS) and carries a bright, uncoated finish. The 4-flute geometry provides good chip clearance and consistent thread form across the full 1-inch thread length. The set spans the standard taper, plug, and bottoming tap sequence, allowing machinists and tradespeople to start, advance, and finish threads in a single progressive operation. Overall length is 2.5 inches. Thread direction is right-hand. Thread limit is H2, suited for general-purpose threading applications where close tolerances are required.

This tap set is used in machine shops, maintenance facilities, and field service applications wherever 1/4-20 UNC threads need to be cut or restored. The 1/4-20 UNC size is one of the most common fastener thread standards in HVAC equipment assembly, electrical enclosures, and light structural work, making this set a practical addition to any service van or shop bench. The taper-plug-bottoming progression makes it suitable for through-hole and blind-hole threading in steel, aluminum, and similar materials.

Compatibility

Designed for cutting 1/4-20 UNC right-hand internal threads in through-hole and blind-hole applications across a range of metals including steel and aluminum.

Installation Notes

Threading operations should be performed by a qualified machinist or maintenance technician familiar with hand tapping or machine tapping procedures. Always use appropriate cutting fluid to extend tap life and improve thread finish. Secure the workpiece firmly before tapping to prevent movement that can break the tap or produce off-angle threads. Follow standard shop safety practices, including eye protection, when cutting threads.
