How to Use Torque Tables 1 and 2
Measure diameter of screw being installed.
Count number of threads per inch or use a pitch grade.
Under heading SIZE, look down DIA IN. column until you find diameter of screw being installed. (There will usually
be two lines beginning with same size.)
Under heading SIZE, look down THREADS PER IN. column to find numbers of threads per inch that match number of
threads counted in step 2. (Not required for metric screws.)
