Overview:
This Spur Gear/Chain Adjusting Screw Kit is a genuine Stihl OEM part for keeping chain tension precise on compatible Stihl chainsaws. Built for reliability, it combines a robust steel adjusting screw with a durable high-strength polymer spur gear to give smooth, accurate movement of the tensioning system.
