Socket Head Cap Screws With Fine Thread DIN 912 (ISO 4762) M20x1.5 in Bright Zinc Plated (BZP) high tensile steel class 12

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.
