12-pin bolts
12-pin bolts are widely used in aerospace engineering as they allow for bolts to be driven tightly and at high force. Referred to as a ferry bolt or 12-point flange-head cap screw, the flange diameter and head thickness of a 12-pin bolt are similar to standard socket head cap screws. These comparable characteristics enable the use of 12-pin bolts in situations where a socket head cap screw would normally be used.

Because the head of a 12-pin bolt has multiple sides, it is easy to obtain a secure grip on the bolt. This allows for extremely high torque to be achieved either manually or by a machine, making the bolt a preferred choice in situations where strength and weight are important factors but limited space is available.
