Description
Overview:
The Screw IHSCFM is a steel, countersunk internal hex (Allen) fastener used across a wide range of Husqvarna petrol tools. It provides secure clamping for parts such as rails, guards, covers and handle assemblies, helping to maintain accuracy and safety under tough conditions. The screw's low-profile countersunk head sits flush to prevent snagging, while the socket drive allows positive engagement with an Allen key for controlled tightening. Precision machining supports reliable torque and repeatable fitment during servicing. It is commonly used on Husqvarna disc cutters, including the K1250 Rail and K950 Rescue, and is also found on selected chainsaws, brushcutters, clearing saws and combi tools. A practical replacement when refurbishing equipment or replacing worn or missing fixings.
Key Features:
- Countersunk head sits flush for a tidy, snag-free fit on covers and rails
- Internal hex (Allen) drive offers solid tool engagement and reduced cam-out
- Strong steel construction to handle high clamp loads and vibration
- Precision-cut threads for consistent torque and secure retention
- Suited to heavy-duty, high-vibration tools such as disc cutters and clearing saws
- Direct fit for listed Husqvarna models to simplify maintenance and repairs
- Quick to install with standard Allen keys; minimises downtime on site
- Helps restore alignment of guards and rails for smooth, accurate operation
Typical Applications:
Securing rail assemblies, blade guards, shrouds, covers, handles and other bolted components on Husqvarna disc cutters and handheld outdoor power equipment. Used during routine servicing, repairs, and rebuilds in workshops or on-site, where a reliable, flush-fitting fastener is needed to withstand dust, vibration and frequent use.
