DIN 7984 M10 × 20 Low socket head
DIN 7984 M10 × 20 is a low head socket cap screw with a 20 mm nominal length, on a M10 × 1.25 mm metric thread. Same cylindrical hex socket head as DIN 912 but with roughly half the head height, for assemblies with limited vertical clearance. Lower head means lower permissible preload than a standard DIN 912 of the same size.
