M16 Socket Head Countersunk Screws ISO 10642 (DIN 7991) in A2 Stainless Steel

A countersunk headed screw conforming with ISO 10642 or DIN 7991, requiring a hex key (otherwise known as an Allen key) to fit. The countersunk head is typically used in conjunction with a countersunk hole providing a flush, snag free fit. Generally manufactured with a full thread, though occasionally some stock may include a partially threaded shank. The head diameter is slightly larger than that of the equivalent DIN 965 Phillips or Pozi driven screw.
