Hi,

I am simply looking for a resource to look up the Maximum Allowable Stem Torque (MAST). We use stainless steel round bar with ACME threads cut into it. I know the MAST will vary depending on the exact configuration of thread but unless I am misunderstanding something, I believe these would be exact constant numbers that I could just look up in a chart. If anybody is aware of such a resource or can inform me that I am misunderstanding MAST, Please let me know!

Thanks
Sandro
