Industrial Card A 1 17 32-20 Plug Hand Tap 6 Flute NS CG HS1 Hand Tap

This plug hand tap measures 1-17/32 in. in diameter with 20 threads per inch and features a 6-flute configuration. It carries the NS CG HS1 designation, identifying its model code within this hand-tapping family. Hand taps are used to cut internal threads in holes, typically with a tap wrench or tapping handle to form precise female threads in metal components. The plug-style geometry indicates the cutting portion extends along a defined length of the tool, aligning with standard tapping practices for creating robust internal threads. This size and pitch pair—1-17/32 in. diameter and 20 TPI—supports common thread ranges encountered in mechanical assemblies, enabling reliable fastener engagement. The 6-flute design is characteristic of this tap style and is suited to tasks where straightforward threading is required in clean, straight holes.
