Inch Nuts and Bolts
1. Listed torques are based on clean dry threads.2. Reduce torque 10% if both parts are thoroughly soaked in oil.3. Reduce torque 20% if "never-seez" or "molycoat" is used on the threads and under the bolt head.4. Reduce torque an additional 20% if new plated (bright) bolts are used.5. Increase torque 20% if multiple tapered tooth lockwashers are used.6. Suggested torques result in clamp loads equal to 75% of proof load. All values given are based on adequate thread engagement. Bolts threaded into aluminum may require reductions in torque of 30% or more unless inserts are used.Inch Taperlock Studs

SAE 37° Alternate Tightening Method
A. SAE 37° Alternate Tightening Method 1. Here is a foolproof method of tightening. Anyone can tell if the joint was tightened and how much: a. Tighten nut finger tight until it bottoms the seats. b. Mark a line lengthwise on the nut and extend it onto the adapter. Use an ink pen or marker.c. Using a wrench, rotate the nut to tighten. Turn the nut the amount shown in the chart on next page.
The misalignment of the marks will show how much the nut was tightened and, best of all, that it has been tightened.

Torques for Other Fittings
A. Ermeto Tube Fittings
1. Put nut and sleeve over the tube with head or shoulder end of sleeve next to nut. Push tube into counterbore of fitting body as far as possible. Turn nut clockwise until sleeve holds tube and prevents movement. Tighten the nut 1 1/4 turns more to seat sleeve and give a locking action. When necessary to assemble again, put sleeve over tube and tighten nut until a sudden increase in torque is felt. Then tighten 1/6 to 1/3 turn more to seat the sleeve. B. Flex Fittings
1. Put nut and sleeve over tubing and push tube into counterbore of fitting body as far as possible. Tighten the nut until it is against the hex part of the fitting body. C. Hi Duty (Shear Sleeve) Tube Fittings
1. After tube has been put through the nut and makes contact against the tube shoulder in the fitting body, turn the nut with a wrench until a small decrease in torque is felt. This is an indication that the sleeve has been broken off of the nut. Hold the tube to prevent turning and tighten the nut 1 and 1/2 turns. D. Hi Seal Fittings
1. Put nut and sleeve over the tubing with the short heavy end of the sleeve facing the end of tubing. Put the tube end against the counterbore in the body of the fitting and tighten until nut is over the last thread on the body. The remainder
