Description
Overview:
The Collar Screw D9/M8 is a genuine Stihl fastener for mid-range petrol chainsaws, including the MS 271 and MS 271 C. Made from durable metal, it is engineered for secure clamping where a collar (flanged) profile is required, helping to keep assemblies tight under vibration. The M8 thread provides strong engagement, while the D9 collar supports stable seating against mating parts for repeatable alignment. This screw is used during routine servicing and repairs to maintain safe, reliable cutting performance. Built to OEM specification, it fits correctly first time and withstands everyday site and forestry conditions. It is an ideal replacement when original fittings are worn, missing, or damaged through use.
Key Features:
- Genuine Stihl part for assured compatibility and fit
- M8 thread with D9 collar format for stable, centred clamping
- Durable metal construction for long service life under vibration
- Manufactured to OEM standards for consistent performance
- Helps prevent loosening and misalignment in assemblies
- Suitable for maintenance and repair tasks on compatible models
- Straightforward fitting with standard workshop tools
- Supports safe operation by keeping components securely fastened
Typical Applications:
Used to secure components within chainsaw assemblies where a collared or flanged screw is specified. Common during bar and body servicing, handle and guard refits, and general rebuilds. Ideal for replacing damaged or missing fixings to restore factory-tightness and reliability in professional, farm, and domestic cutting work.
