TM 9-2815-220-24 TORQUE LIMIT TABLES 0174 00 STANDARD TORQUE LIMIT TABLES NOTE All torque values – Special and Standard – are with lubrication unless otherwise specified. Torque values for dry fasteners would be different. Pay attention to lubrication notes. See Lubrication Notes on page 1 of this work package 1. To use standard torque tables: a. Measure the diameter of the screw, nut, pipe plug, or stud you are installing. b. Use the appropriate table: Screws and nuts (Table 2) Pipe plugs (Table 3) Studs (Table 4) c. Under the heading “Size (Diameter, Inch),” look in the left column until you find the diameter of the nut, bolt, screw, stud or pipe you are installing. Then read across the table to find the proper torque limit. TABLE 2: STANDARD SCREW AND NUT TORQUE LIMITS Apply Lubriplate (item 23, WP 0173) to bolts, cap screw threads, contact face of nuts, bolt heads, and cap screws. Avoid excessive amounts of lubricant in blind tapped holes. NOTE On assemblies subjected to wire or cotter pin alignment, set torque wrench to low limit and torque nut. To facilitate alignment, it is permissible to tighten nut to first hole beyond torque setting.
