Appendix F Torque Limits

F-1. INTRODUCTION.

a. This appendix includes a standard torque table of the most commonly torqued screws, bolts, and nuts.

b. These torque values may be used when torque values are not specified.

c. The torque table values are given in inch-pounds If a torque wrench is calibrated in foot-pounds, you need to divide the listed number by 12 to obtain the desired torque.
