Brass 360 Dowel Pins
Free-machining brass — excellent machinability.
C360 is the free-machining brass and one of the easiest materials on this list to turn to a tight tolerance. As a pin it is non-magnetic and non-sparking, which is why it appears in instrument, electrical and hazardous-area work. It is soft compared to the stainlesses, so it locates well but wears quickly under repeated assembly, and it will tarnish in open air without affecting fit.
Brass pins are specified for what they do not do: they do not spark, they are not magnetic, and they will not mark a softer mating surface as readily as steel. Those are the reasons worth paying for; brass is otherwise the softest option here.
Any size, not a series
There is no size list here because there is no catalogue: diameters run from 0.015" to 0.375", including sizes between two standard ones, and lengths from 0.02" to 4" — turned to order rather than cut down from a stock pin and re-finished. Pricing in Brass 360 starts at $3.40 per piece at 100 off, and falls further at higher volumes.
