Description
Overview:
The M5x40 screw is a metric machine fastener used across Husqvarna chainsaws and handheld machines, including the 435 and 440. Built from robust steel and made to Husqvarna OEM sizing, it is used to secure key assemblies so the tool stays aligned and dependable under vibration. The M5 thread provides a secure engagement in factory threads, while the 40 mm length gives suitable reach for common housings and covers. This replacement screw supports routine maintenance and repairs where the original fastener has been lost, damaged, or corroded. Supplied to OEM reference 503 20 02 40, it helps maintain the integrity of the chassis, guards, and handle components in demanding cutting environments.
Key Features:
- OEM-spec M5 x 40 mm sizing for a precise fit
- Strong steel construction suited to high-vibration tools
- Consistent clamping force helps keep components aligned
- Clean, accurate threads to aid easy hand-starting and tightening
- Suitable for multiple Husqvarna platforms listed below
- Helps prevent loosening and premature wear in service
- Direct replacement for missing or worn original screws
- Supports routine servicing with reliable repeatability
Typical Applications:
Securing covers, housings, chain brake assemblies, guards, handle sections, and other subassemblies on compatible Husqvarna chainsaws and handheld machines. Ideal for replacing damaged or stripped fasteners during maintenance, overhaul, or after accidental loss in the field. Suitable for both workshop repairs and on-site fixes where a correct-length M5 machine screw is required.
