Coupling Bolts (Grade 5)

Coupling bolts are manufactured from Grade 5 high-strength carbon steel. The shank length of a coupling bolt is equal to the measured outside diameter of the center pipe of the screw to provide maximum shear area and strength. It is very important to only use the correct coupling bolt for corresponding screw and pipe size.
