M20 x 1.5 x 65mm Fine Pitch Socket Head Cap Screw in 12.9 Bright Zinc Plated - DIN 912 (ISO4762)

Fine pitch screws are used in conjunction with a fine pitch threaded hole, or with fine pitch nuts which are also available on this website. The extra thread engagement gained from the finer pitch gives a more secure and stronger fitment. Used where high levels of strength are required - a fine pitch bolt has a larger stress area creating better tension than its coarse pitch counterpart, also they are less inclined to loosening through vibration due to the thread incline being smaller.
