[QUOTE="Clark, post: 692187, member: 6600"] I look up the max torque for that screw size. Then I have to know what grade screw it is. Then I have to measure how much engagement with the female threads. Then I have to evaluate the female material; Steel is best, but it may be cast iron or Aluminum. If engagement is more than 1.5 times the root [minor diameter of the screw] the screw is probably the weak link. Then I have to evaluate the lubrication. Wax makes for much more tension from the same torque. Oil and grease not so much. Clean and dry is the least. Then I calibrate the torque wrench. I use as standards, a ruler and a weight that I weighed on a balance beam. Then I do a destructive test on sample material to verity my calculation is correct. If the female is the weak link, I mill sample material to the same thickness. Most guys just want a recipe answer. [/QUOTE]
