Selecting and Fitting Your Cap Nuts
Select the required thread size and pack quantity from the available options. The stated size refers to the internal thread diameter. Match both the diameter and pitch to your bolt, screw or stud.
Check the protruding thread length before fitting. The bolt or stud must not bottom out inside the closed cap before the nut clamps the components securely.
