Nut for sheet metal or wood screws Long nut initially realized to fasten electronic boards or other components on a plate to be drilled, here an LM317. The assembly consists of the nut and a breakable strip of washers, to separate with a cutter or by folding (washers with chamfer on the screw side, and bevel on the electronic card side to make spacer) The example is oriented for sheet metal or wood screws, 2.5 to 3 mm in diameter (The nut has a length of 12 mm) Possibility to change dimensions, the Freecad file is available, it may be simpler to simply change the scale of printing (what I did to fix the cover). It is preferable to perform an unloading screwing to "thread" the nut before mounting.
