Electronics Instrumentation = D 1 minus 0.020 for 10 threads per inch and coarser and 0.010 for finer pitches. While the square form was relatively efficient for the purposes required, it was inherently weak at the base of the thread due to the sharp 90-degree angle of the flank. For Acme thread calculations go to our Acme Thread Calculator. What happens next? were designed to replace square threads and a variety of other formed threads to produce traversing motions on machines, tools, and for heavy load work. The tensile load rating and torsional load rating on the double shoulder connection are 1.2e6 lb and 68000 ft-lb respectively. The UN thread is also of shallow geometry but achieve their strength over length of engagement and good for thin wall applications.

Acme/Stub Acme Thread Torque and Axial Load Calculation Once thread box/pin nose has stopped moving and the box/pin makes contact at the internal or external shoulder (see Figure 4 and 5), additional torque is translated into tension or compression causing an axial stress applied across the thread relief of the box for contact at the internal Engineering Book Store 2023 The American Society of Mechanical Engineers. Already a Member? The tolerance on the internal thread major diameter is 0.020 inch for 10 threads per inch and coarser and 0.010 for finer pitches.

A good fitting 60o thread will make up hard with only 5 to 10o of rotation where as the Acme threads on military rifles normally. Additionally, potential involved labor is minimized, and possible waste disposal and handling costs are greatly reduced. I guess the questions ( based upon these loads) are: I would follow the API Specification 7 & 7G for the connection strength calculations and compare the same calculation to other geometries. leon and edelstein's latin delicatessen,
