150pc Assorted Box of Setscrews - 150 bright zinc plated metric setscrews to DIN 933 in seven size and length combinations, covering M5, M6, M8 and M10 in lengths from 20mm to 40mm.
A setscrew is a hex head bolt threaded all the way to the head rather than part way, so it grips from the first turn and holds well in a tapped hole or a short clamped joint where a partly threaded bolt would run out of thread. The hex head takes an ordinary spanner or socket. Useful sizes to have boxed up for brackets and mountings, trailers, machinery repairs and general workshop work.
