Description
Overview:
This Adjusting Screw is a Genuine Stihl OEM component designed for the chain tension system on selected Stihl chainsaws, including the MS 240 and 024. Built from durable metal with a precise thread, it provides smooth, controlled movement to set and maintain correct chain tension. Keeping the chain at the right tension helps the bar and chain run straight, reduces wear, and supports safe, efficient cutting. The screw is a direct-fit replacement for machines that specify Stihl part number 1121 664 1600, restoring the original adjustment feel when the factory screw is worn, stripped, or lost. Suitable for both professional and home users, it fits neatly into the existing adjuster mechanism and helps keep routine maintenance quick and reliable.
