Description
Overview:
The Self-Tapping Screw M5x20 is a genuine Stihl OEM fastener designed for reliable use in petrol lawn mowers and similar machinery. It features an M5 thread with a 20 mm length for secure assembly of components that require a strong fixing without pre-tapping. Made from quality steel with a corrosion-resistant finish, it suits outdoor environments and regular mower use. The self-tapping design forms its own thread in suitable materials, helping to speed up maintenance and reduce downtime. It is intended for Stihl and Viking applications, including popular walk-behind models such as the MB 545.0 VR and MB 650.0 VR. Use this screw to replace worn, missing, or damaged fixings and maintain the integrity of covers, housings, guards, and structural brackets on your machine.
Key Features:
- Genuine Stihl part for assured fit and performance on compatible mowers
- M5 x 20 mm size for common mower fastening points and service tasks
- Self-tapping thread forms its own mating thread, reducing the need for pre-drilling in specified materials

- Identified by Stihl part number 9039 488 0982 for straightforward cross-referencing
Typical Applications:
Used for fixing mower deck covers, engine shrouds, belt or drive guards, cable guides, handle assemblies, and other fittings on compatible Stihl and Viking petrol lawn mowers. Also useful for general repairs where an M5 x 20 mm self-tapping fastener is required, provided the base material and hole preparation are suitable for a thread-forming screw.
