Description
Overview:
This Chain Tensioning Nut is a Genuine Stihl OEM part for maintaining precise chain adjustment on Stihl chainsaws and electric saws. Made from durable metal, it sits within the chain tensioner mechanism to help keep the chain correctly aligned and running smoothly under load. By allowing accurate, repeatable adjustment, it supports safe cutting and reduces wear on the bar and chain. It is widely used across many Stihl machines, including MS 170 and MS 180, and is suited to both professional users and home owners. If your chain tension is drifting, adjustment feels rough, or a service identifies a worn nut, replacing it with this original part (Stihl 1120 664 1500) restores proper function and extends the life of the saw's drive components.
Key Features:
- Genuine Stihl part for reliable fit and function across a wide model range
- Robust metal construction for long service life in demanding cutting conditions
- Helps maintain correct chain alignment and stable tension during operation
- Smooth, precise adjustment to support safe cutting and consistent performance
- Direct replacement for worn or damaged tensioning hardware
- Optimised to work with Stihl's OEM tensioner components for best results
- Simple to fit during routine maintenance with standard workshop tools
Typical Applications:
Replacing a worn or missing chain tensioning nut during servicing, bar and chain changes, or after heavy use. Useful when chain tension is difficult to set, drifts during work, or when the adjuster feels rough. Helps restore smooth tensioning for tasks such as logging, pruning, firewood cutting, and site clearance.
Also known as:
Chain adjuster nut, tension adjuster nut, chain tensioner nut, tensioning screw nut, chain adjuster retaining nut, tensioner fixing nut.
