This appendix provides general torque limits for the screws, hoses, and fittings used on the Laser Leveling
Equipment. Special torque limits are listed in the maintenance procedures for applicable components. The
general torque limits given in this appendix shall be used when specific torque limits are not indicated in the
maintenance procedure. These general torque limits cannot be applied to screws that retain rubber
components. The rubber components will be damaged before the torque limit is reached. If a special torque
limit is not given in the maintenance instructions, tighten the screw or nut until it touches the metal bracket,
then tighten it one more turn.
Section II. TORQUE LIMITS
J-2. TORQUE LIMITS.
Table J-1 lists the torque limits for wet flange nuts. Table J-2 lists the torque limits for wet socket head
capscrews. Table J-3 lists torque limits for dry fasteners. Dry torque limits are used on screws that do not
have high pressure lubricants applied to the threads. Table J-4 lists torque limit for wet fasteners. Wet torque
limits are used on screws that have high pressure lubricants applied to the threads. Table J-5 lists the torque
limits for SAE 37-degree flare hose connections. Table J-6 lists the torque limits for SAE 45-degree flare hose
connections. Table J-7 lists the torque limits for ORS preformed packing face seal hose connections. Table J-8
lists the torque limits for NPSM swivel connections.
