Our M6-1.0 Allen screw and nut for chain tensioners is an important part of the drive system and should be replaced if damaged or lost. If you have a loose or missing tensioner screw and nut, then you have a faulty chain tensioner. This can be identified by a loose chain that falls off during ride time.
Our screw and nut combination is compatible with a many chain tensioners used on small recreational scooter, dirt bikes, and mini bikes.
