ACME Tap

ACME 29 tooth-shaped trapezoidal  tap (ACME), said: inch diameter + inch pernumber of teeth + tolerance code (usually 2G, 3G, accuracy of 2G), such as: 1 / 4-16ACME -2G, and then 5 / 8-8-ACME-3G.

Note 1:  tapping material: HSS.
Note 2:  ACME thread tap, most need to send order then production, can also provide ACME accuracy of 2G and 3G plug (detection of internal thread), ring gauge (detection of external thread).

ACME  Tap specifications are: 1 / 4-16ACME-2G, 5 / 16-14ACME-2G, 3 / 8-12ACME-2G, 1 / 2-10ACME-2G, 5 / 8- 8ACME-2G, 3 / 4-6ACME-2G, 7 / 8-6ACME-2G, 1-5ACME-2G, etc.,

Because the particularity of the ACME thread usually requires a special design, this thread allows rotation and lateral movement on the machine.Each size can be production.
