A flat sunk bolt with an Allan head was torn out, the hex key had no grip and the sunk bolt could not be grasped with pliers. It was a fat bolt so drilling out would have been very difficult.
No parts required.
Cut a slot into the screw head.
Place a screwdriver in the slot and tap with a hammer in the counter-clockwise sense to loosen the bolt.
Unscrew the bolt with the driver.
