Metric DIN 7991 hexagon socket cap screws have a flat countersunk head with an internal hexagonal drive suited for a hex / Allen key or wrench. The internal drive is ideal for situations where externally wrenched screws are impractical such as in applications where limited space is available. Furthermore the flat countersunk head allows for the head to lie flush with the surface of the substrate. .
