Added security to the hinged side of the door

Hinge Bolts provide the necessary attack protection to the hinged side of a security door, with hinges often sacrificial in the case of attack. Outward opening doors in particular are often vulnerable on the hinged side, as the hinges are clearly visible to the attacker.

The hinge bolt pin is fitted in and projecting from the hinged edge of the door, and is received into its keep as the door reaches its closed position.
