Replaced sprocket segments, One hole was stripped one bolt broke off. Bolt has a 19mm head and thought was 12mm bolt so ordered a helicoil kit with a 12mm 1.25 pitch. I tapped the hole all the way through and threaded the helicoil in by hand, Cannot get that bolt to start. It seems a hair larger maybe its a 1/2 inch fine thread bolt with a 19mm head ? Maybe the head is 3/4. However the nuts that came ith the new bolts had "12" stamped on them. A 15 minute job has been a couple hours and still not accomplished. Any insight would be appreciated.
Thanks

It is a normal USA thread not metric
the 19 mm head matches a 3/4 !!! |
