Misc / Open / General part number decipher
« on: February 25, 2023, 08:49:58 PM »
Already trying all evening to find a post where part number code's for general parts are explained. How can one tell if a hex bolt is chromed or zinc plated from the part number?
General part numbers have this format:
xxxxx-xxxxx-yy
I am interested in the YY designation. I've seen 4J, OA, OB, O2, O7 etc. I am assuming that OB means chromed. Is that correct? And does this also apply on nuts and washers?
Cheers.
