A spare set of two M7x1.00 x 15mm set screws for standard go-kart and mini bike clutch collars could easily keep a day of offroading fun from becoming a frustrating day of not going anywhere. Headless set screws such as the M7x1.00 x 15mm set screw are used to "lock down" an adjustable part. Many go-kart and mini bike brands use this size screw in a number of applications, primarily with clutch collar assemblies.
This black-finished set screw will provide the holding power to keep that clutch collar right where you want it to stay.
