I'm trying to understand this technical drawing. It's supposed to be a piston rod of a shock absorber. There is supposed to be a screw-thread somewhere, but I can't see where. Also, what the hell does the cross mean at the left?
there are threaded ends at both ends. m10x1 is a threaded end and 5/16-24 unf is a threaded end.
not sure what the X is or if you cut off some of the label pointing to it but since its a shock piston it is likely some form of adjustment. either keyed or hex or knurled.
Do you see the little lines right near the thicker ones? Designated with metric and UNF thread specs? That's how they draw threads these days (these days being at least a hundred years if not more). see also http://www.engineeringessentials.com/ege/fast/fast_page5.htm
It's like they know something that the whole of /diy/ doesn't, that we can live in peace and harmony, coexisting side by side, that both have desirable qualities and we should ask just get along... Yeah that, or they fucked up.
It's disgusting. I saw the 5/16 thread first so it took me a moment to realize what the other numbers were because there's no such thing as a 400 inch shock outside of maybe those massive dump-trucks the size of houses.
