Torque Limits
Table 1 lists dry torque limits. Dry torque limits are used on screws that do not have lubricants applied to the threads. Table
2 lists wet torque limits. Wet torque limits are used on screws that have high-pressure lubricants applied to the threads.

How to Use Torque Table
a.
Measure the diameter (dia.) of the screw you are installing.
b.
Count the number of threads per 1 inch (in.) (25.4 millimeters [mm] ) or use a pitch gage.
c.
Under the heading Size, look down the left-hand column until you find the dia. of the screw you are installing (there
will usually be two lines beginning with the same size).
d.
In the second column under Size, find the number of threads per 1 in. (25.4 mm) that matches the number of threads
you counted in step 2b.
e.
To find the grade screw you are installing, match the markings on the head to the correct picture of SAE Cap Screw
Head Markings on the torque table.
f.
Look down the column under the picture you found in step 2a until you find the torque limit in pound-feet (lb-ft) or
Newton-meters (Nm) for the diameter and threads per 1 in. (25.4 mm) of the screw you are installing.
