My Designs require 304SS or 316SS fasteners in the 1/2-13 to 1.25-7 range. Does anyone know of any published or listed recomended torque tables for stainless steel?
 

Be careful using torque tables on 304 or 316 stainless fasteners - lot of variables exist that can make a difference. Number of sites carry these same numbers, but none document their source.
 
Thanks Paskenell

I have found these mystery tables you speak of but I was looking for the source also.
Thanks again.
 
Gregmon,

You might be better off working out the torques yourself. It is very easy to generate torque tables with a spreadsheet, and very difficult to find consistent allowable stresses for work hardening materials like 304/316SS. I have seen yield stresses quoted as low as 55KSI for stainless steel cap screws.

304 & 316 threaded fasteners are very susceptible to galling. Suggest taking precautions; see
