New old stock m6 pulley bolt for solex mopeds. These were picked up from a dealer buyout and were mixed in with Jawa, Batavus, Trac, Safari, Solex and Cimatti Moped parts. So as long as the measurements match what you are looking for these could work for a variety of bikes. Great shape and ready to ship as is.
m6 1mm treading. 12mm thread. 9mm hex head
