Trapezoidal screw threads were devised to allow rotary and transversing motion on machines; And are also used in jacks, valves, presses and other mechanisms where heavy loads are encountered. The trapezoidal thread is characterized by a 30° Included angle. Trapezoidal taps typically require specialized engineering and design due to the nature and severity of cut required in producing trapezoidal threads.
( The acme thread is characterized by a 29° Included angle)
TANDEM ACME TAP
These taps combine the initial roughing cut with the final finishing cut, in one pass, to achieve an acme screw thread. These taps are economical and enhance production levels by saving on the operation of two tools. Since acme thread pitches are generally coarse relative to diameters, these taps are subjected to heavy chip loads. To achieve a high quality acme thread in a cost-effective manner, roughing and finishing operations are recommended.
