This genuine Stihl chain adjusting screw kit is designed to restore precise and reliable chain tensioning on professional petrol chainsaws. Constructed with durable metal components and reinforced composite parts, it is built to withstand vibration, debris, and frequent adjustment in demanding forestry and jobsite conditions. Proper chain tension helps maintain correct guide bar alignment, supports clean cutting performance, and reduces unnecessary wear on the bar and drive components. Engineered as a direct replacement for the adjuster assembly on compatible Stihl models, including the 088 and MS 780, this kit is suitable for servicing or repairing a worn or damaged original mechanism.
