Hey guys ans gals,
I am thinking about freshening up my under carriage (the car's, not myself) and looking to order a few replacment bolts for my fromt a-arms and rear torsion plate. I've looked at McMaster Carr's cat and wondering what is the grading system they have and what grade sould I purchase?. I know that metalurgy is very important in the selection of hardwares. Also, I like the Cadnium (carcinogen) plated hardware and it seems that McMaster Carr only carries them in standard and zin plated in metric. Are ther any other sources for cad plated metric hardware?. Thanks. Andy
