ACME Tandem Taps Can Be Used For Nuts With Maximum Thread.
ACME Tandem Taps are made of high speed steel for long lasting durability and dependability. Unique design combines the initial roughing cut with the final finishing cut in a single pass to achieve an ACME screw thread. Thread pitches are generally coarse relative to diameters, so these taps are subjected to heavy chip loads. Available in a wide selection of 1/2-10 to 1-5 thread sizes with 2-9/16 to 5-7/8 inchthread lengths and 5 to 12-5/8 inch overall lengths. Imported.
