Screw Extractor Set

So after tightening up all those nuts, bolts and hex screws, suppose the unthinkable happens, the head shears or the recess becomes rounded. To remove such troublesome items reach for the stud extractor set. A small hole is drilled down the centre of the offending stud and the appropriate extractor inserted, turning the extractor anti-clockwise so it tightens it in the hole and automatically loosens the broken stud. Set of five high-speed steel extractors, for common stud sizes M3 to M18, 1/8" to 19/64". Guaranteed to help you unwind.
