Im new around here, and im looking for a crank bolt for a hollowtech pedal. Im not sure what kind of pedal it is but the bolt had gone missing. I haven't ridden my bike for weeks. Im just looking what size of bolt i need.
M19X1 seems to be the right size but I couldn't screw it in
M20 is too big.
Im planning on buying M18 and M19 to see which fits.
Any suggestions? Advice?
Pls i haven't ridden my bike, im going insane fr

That is a special bolt that you need to get from a bike shop.
Amazon have cheap ones in whatever colour you desire. Shimano Hollowtech preload. And only do it slightly tighter that finger tight.[Shimano preload cap](https://www.amazon.co.uk/Shimano-FC-7900-Crank-Arm-Fixing-Bolt/dp/B007R4O0JO/ref=mp_s_a_1_1?crid=3MIK9QYFPKT65&dib=eyJ2IjoiMSJ9.V5PNJe135v9V5FKWUnyjjZEDFIqnMlcTSVsV7QzniIIb1l4JnbTv1Ris9ydE3BhfH-zVu2tX2ADfUCGUsq4EunhvWYtVjme4QdueK1e4gdTWkmOUK5qi3gm-nAWim0uUGoy4KqSmjtpOVwdFaj8Bk8E4QQpabIQumcooM4WNYSF5tH2-XGJx0pJDvLrr6s2sAry36OkpagFrPTCRzh9HXQ.MPbsETBRlHV4AvmkaAxAKjLZ22_nZV1l65Bo73eOAqo&dib_tag=se&keywords=shimano+preload+cap&qid=1759518737&sprefix=shimano+preload%2Caps%2C110&sr=8-1)
They’re a generic Shimano part
