A bolt is employed as a fixture in conjunction with a nut. The bolt has a tapered tip (2) which serves to facilitate easy fitting through a pre-drilled hole, following which the nut is applied and tightened. The bolt shank (1) is linked to the tip (2) via a waisted (3) weak point. The tip has a groove (4) to receive a screwdriver.
