The studs are screwed into the body of the Good Luck chainsaw and hold the bar and the clutch cover. The mounting nuts thread onto them. Country of origin: China.
Replace them if the thread is stripped, or they are bent or cracked: the bar will not be held well. Choose by the length and thread of your saw.
Good preventive care: regularly clean the saw of sawdust and resin, use fresh fuel mixture and chain oil suited to the season.
