HOW TO USE TORQUE TABLE-Continued
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).
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 2.
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.
Look down the column under the picture you found in step 5 until you find the torque limit in pound-feet (lb- ft) or
Newton-meters (N-m) for the diameter and threads per 1 in. (25.4 mm) of the screw you are installing.
