Just to add to that message (can you edit posts on this forum?)
I have heard you can take the Ratio of TPI x torque to get the resulting torque of the fine thread fastener. Is this an accurate statement?
Thanks again,

Disclaimer: I havent had much experience with this as I am still new to the field, so forgive me if this sounds foolish.
Are you saying it will take 140ftlbs of torque on a fine thread screw to match the holding power of 120ftlbs of a course thread screw? It just seems backwards to me, I...
Thats true, maybe I'm over thinking this. Yes I want the load to be the same or close to what it currently is. I just need to figure out the difference in torque applied to the set screw to obtain that 'load' to avoid overtightening.
Thanks for the quick replys!

With a bolt, when you tighten it you are banking on the bolt head (assuming no nut). With a set screw, there is no stop you are banking on the bottom, and in this case the bottom is flat I'm not sure if the surface area of the set screw (flat bottom) would be equal to the surface area of a bolt...
Hey guys,
I'm new here, so I hope this is in the correct area. I have a question about torque of a SET SCREW as it relates to force applied. Specifically in machine tool holders (endmill holders).
It has been decided to change from course thread to fine thread set screws on the holders, but...
