Plug Taps

When you need clean internal threads without fighting the tap, grab our Plug Taps. Precision ground, hand-polished threads cut true, and 4 flutes spread the load to reduce breakage. Run HSS for everyday steel, step up to SP+ Ferro-Gold or TiN when stainless gets stubborn. We stock SAE, USS and metric, including machine screw sizes.
