If the nylocs are at the point of needed replating then you really shouldn't be re-using them as the nylon simply wont be effective anymore. Just buy new ones - it must be more cost effective than getting a small batch of stuff plated anyway? Try Kenton Fasteners - http://www.applegate.co.uk/all-indus...le-1177367.htm - good guys and stock most stuff in a1/a2 stainless, BZP, chemically blackened, etc
