About Carbon Taps: Carbon Steel Hand Taps are used to re - thread damaged and/or jammed threads. Carbon Steel Hand Taps may also be used to thread mild steels. Taper Style: Starts the thread square with the workpiece. Plug Style: Generally used in thru holes. Bottom Style: Generate the thread to the bottom of the hole. About Carbon Round Adjustable Dies: For re - threading, a Carbon Steel Round Adjustable Die is desired for improved wear life. Round Dies are chamfered on both faces. 1 side has a 2 to 3 thread chamfer for threading, the other side has a 1 in. to 1 - 1/2 in. thread chamfer for threading close to a shoulder. Adjustment is obtained by a fine pitch screw which forces the sides of the die apart or allows them to spring together. The slot is beveled so that when the dies are used in a machine holder the adjusting screw can be removed and adjustment made by the adjusting screws in the holder.
