Description

Overview:
The Exhaust Muffler Screw is a small but important fastener used to secure the exhaust muffler (silencer) on compatible Husqvarna chainsaws. Built from durable metal to handle heat, vibration, and outdoor use, it keeps the muffler firmly attached to maintain proper back pressure and minimise exhaust leaks. This helps preserve engine performance and noise control during tough cutting work. It is suitable for professional and domestic users maintaining saws such as the Husqvarna 562 and 570, among other models in the same family. For easy identification, this screw corresponds to Husqvarna reference 503 20 73‐20 (503207320). Use it as a like-for-like replacement when original fasteners are worn, damaged, missing, or no longer holding torque.

Key Features:
- Designed to fasten the exhaust muffler securely to the engine body on listed Husqvarna chainsaws
- Durable metal construction to withstand vibration, heat cycles, and regular use in forestry and landscaping environments
- Helps maintain a tight muffler seal to reduce the risk of exhaust leaks and performance loss
- Direct replacement fit for the specified models, avoiding guesswork on length and thread compatibility
- Clean, precise threading for straightforward installation with basic hand tools
- Suitable for routine maintenance, rebuilds, and post-vibration checks when fasteners need replacing
- Stable clamping under load to resist loosening during extended cutting sessions

Typical Applications:
Used during muffler replacement, servicing, or rebuilds on Husqvarna chainsaws to restore a secure exhaust mounting. Ideal when an original screw has rounded heads, stripped threads, corrosion, or has been lost. Common in forestry, arborist work, construction site preparation, estate management, and general grounds maintenance.

Also known as:
Muffler bolt, exhaust bolt, muffler screw, exhaust screw, silencer bolt, silencer screw, chainsaw exhaust fastener, exhaust mounting screw, muffler fixing screw.
