- M4 20 Series T/V-Slot Slide In Nuts are a robust fastening solution designed for use with aluminium extrusion systems. The functional nut features a design that slides into the T/V-Slot of the extrusion from the end, providing a secure high-strength anchor point. Zinc-plated for improved corrosion resistance, these nuts offer a balance of affordability and basic functionality for demanding applications in modular framing and heavy-duty assemblies. Pros and Cons Slide In Nuts are a high-strength solution for applications with moderate to high load requirements. Pros Cons High Strength: These nuts offer the highest pull-out force among our extrusion nuts. Reliable Engagement: Sliding in from the extrusion end ensures full contact with the T/V-Slot, maximising available strength. Corrosion resistant: Zinc plating provides basic protection against rust. End insertion only: Cannot be added after frame assembly, limiting flexibility. Advanced planning required: Number and placement of nuts must be determined before assembly. Application Slide In Nuts are specifically designed to complement our aluminium extrusion systems, providing secure and high-strength fastening for a wide range of structures and assemblies. Ideal for both professional engineers and DIY enthusiasts, these nuts excel in applications requiring higher load-bearing capacity. Their ease of use and compatibility make them a practical choice for any project requiring efficient and secure assembly.
