The VALUE COLLECTION JY4844320 is a straight flute plug tap designed for cutting 1/2-32 UNS internal threads in a wide range of materials. Built from high-speed steel with a bright uncoated finish, this tap delivers consistent thread form in machining and maintenance applications. The plug chamfer, with its moderate lead-in, makes it suitable for through-hole threading where the tap can advance freely through the workpiece. At 3-3/8 inches overall length with 4 flutes and an H3 thread limit, it provides the clearance and chip control needed for standard production and repair work.
This tap is used by machinists, tool and die makers, and maintenance technicians working on assemblies that require 1/2-32 UNS threading. The UNS designation indicates a non-standard thread pitch outside the unified coarse and fine series, making this tap appropriate for specialized fastening applications in aerospace, instrumentation, and mechanical assemblies where a 32 TPI pitch at 1/2 inch diameter is specified. Right-hand thread direction matches standard fastener orientation.
Designed for use in applications requiring 1/2-32 UNS internal threads; compatible with standard tap handles, tapping heads, and CNC machine tool holders sized for 1/2 inch shank taps.
This tap is installed by machinists or maintenance technicians using a tap wrench, tapping stand, or CNC tapping head. Always secure the workpiece before threading and apply appropriate cutting fluid to extend tool life and improve thread quality. Ensure the tap is properly aligned to the hole axis before applying torque to prevent tap breakage. Inspect the tap for wear or chipping before each use, particularly when threading harder materials.
