Value Collection MSC-04474169 Tap Set 1/2-13 Unc Hss

Product Description

The VALUE COLLECTION MSC-04474169 is a 3-piece tap set designed for cutting 1/2-13 UNC internal threads in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this set delivers reliable performance in general-purpose threading applications. The 4-flute geometry provides balanced chip evacuation and cutting stability in through-hole and blind-hole configurations. With an overall length of 3.375 inches and a thread length of 1.656 inches, the taps are sized for standard hand-tap driver use. Thread limit is H3, suited for class 2B and 3B fit tolerances. Machinists, maintenance technicians, and tool room professionals will find this set appropriate for production and repair threading work.

This tap set is suited for right-hand threading in ferrous and non-ferrous metals, including steel, aluminum, and cast iron, under typical shop and field-service conditions. The 1/2-13 UNC thread form is one of the most common fastener sizes in mechanical assemblies, making this set a practical addition to any threading inventory. The 3-piece configuration typically includes taper, plug, and bottoming taps to cover the full range of threading situations from starting a thread to reaching the bottom of a blind hole.

Compatibility

Designed for use in any standard tap wrench, T-handle tap driver, or drill press setup capable of accepting 1/2-13 UNC hand taps. Intended for general-purpose threading in metal fabrication, maintenance, and repair applications.

Installation Notes

Threading operations should be performed by qualified machinists or maintenance technicians familiar with proper tap alignment, cutting speed, and lubricant selection for the workpiece material. Always secure the workpiece firmly before starting, use an appropriate cutting fluid to extend tap life and reduce galling, and back off the tap periodically to break and clear chips. Never force a tap against resistance — doing so risks tap breakage and workpiece damage.
