DIN 7984 M16 × 100 Low socket head
DIN 7984 M16 × 100 is a low head socket cap screw with a 100 mm nominal length, on a M16 × 1.5 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.
