The M8 airline rail screw fitting with a clamping range of 0–22 mm is a particularly flexible and robust fastening solution for airline rails. It is ideal for the secure mounting of modules, tools, or outdoor accessories—both inside and outside the vehicle. Thanks to high-quality V2A stainless steel, this screw fitting impresses with its high load capacity, corrosion resistance, and long service life.
The generous clamping range makes this fitting extremely versatile and offers significantly more scope than shorter versions. It fits all standard airline rails and can be flexibly adapted to different material thicknesses.
Flexible for indoor and outdoor installation
The M8 screw fitting is ideal for applications where stability and adaptability are required. Whether in vehicle conversion, craftsmanship, or off-road use, this fitting offers reliable support.
Typical areas of application
- Fastening cabinets, modules, and tools in the cargo area
- Mounting roof tents, sand plates, or canisters on the outside of the vehicle
- Fixing accessories to airline rails on the roof, wall, or floor
By choosing different closure options, the screw fitting can be adapted precisely to the respective application.
Closure variants for every application
The screw fitting is supplied with a self-locking nut as standard and can be combined with other fastening types as an option:
-
Self-locking nut – for permanent, vibration-proof fastenings
-
Star knob – for quick installation and tool-free loosening
-
Knurled nut – ideal for flexible, frequently changing applications
This allows the fitting to be used optimally for both fixed constructions and modular systems.
Robust stainless steel – ideal for outdoor use
Made from high-quality V2A stainless steel, this M8 screw fitting is ideal for use in demanding conditions. The material is:
- corrosion-resistant
- weatherproof
- mechanically resilient
This makes the fitting ideal for permanent outdoor use, for example on roof racks, rear systems, or off-road superstructures.
