TOP TINKERING TIP
In ‘PUB Talk’ a couple of months ago, mention was made about the problem of removing cap head screws when the Allen key no longer gripped in the hexagon of the cap head. A way of getting them out – which I have used many times – is to use a special socket which is made by Irwin for removing normal hexagon head screws when the head is damaged. They work by having reverse, tapered splines in the socket to bite into the head of the screw to grip it. Select one of the appropriate size, hammer it onto the head of the Allen screw. It will work just the same and grip the round screw head to undo it.
It never fails as long as there is a gap around the head of the screw of around 2mm. Swede
