M5 J.I.S Japanese Industrial Standard Zinc Pan Head Screws(10-35mm) with Washer
Choose from 10,12,14,16,18, 20, 25, 30 or 35mm long. We do engine screw kits for motorcycles using J.I.S screws in both stainless and zinc plated steel. With everyone changing to socket cap bolts, there was not much call for these screws so they were not so readily available.
