I bought some proximity sensors on ebay for cheap ($66 for 10) and some are missing the nuts used to mount the sensors. The nuts measure M12 x 1.00 mm. These are hard to find. Does anyone know where I can buy some? If I cannot find any, then I will also need to make my own (using a tap). For the tap method, does anyone know where I can find some square or hex shaped rods made of acetal, delrin, or other plastic preferred material?
Thanks,
