The M8 airline rail screw fitting made of V2A stainless steel is a compact, resilient, and weather-resistant solution for securely fastening components to airline rails. With a clamping range of 0–12 mm, this short screw fitting is ideal for applications that require a flat design and reliable fastening—both inside and outside vehicles.
Thanks to its high-quality stainless steel (V2A) construction, the fitting is permanently corrosion-resistant and designed for professional use in commercial vehicles, motorhomes, off-road vehicles, or roof rack constructions.
Areas of application for the M8 screw fitting for airline rails
The stainless steel screw fitting is inserted directly into the airline rail and enables the form-fit and force-fit fastening of a wide variety of components. Its compact design makes it particularly versatile.
Typical applications in vehicles
In the vehicle interior, the M8 screw fitting is suitable for mounting:
- Cabinets and modules
- Tool holders and equipment systems
- Partitions or lightweight structures
- Customized fittings in campers or service vehicles
Outdoor installation & weather-exposed applications
Thanks to its weather-resistant stainless steel, the screw fitting is also ideal for outdoor use. Typical areas of application are:
- Fastening sand plates
- Mounting of canisters or tool boxes
- Roof rack and off-road superstructures
- Fixing accessories to rear or roof systems
The choice of material plays a decisive role, especially in outdoor applications – here, stainless steel offers clear advantages over galvanized or coated steel variants.
Variants: nut, star knob, or knurled nut
The M8 airline rail screw fitting is available in several versions and can therefore be optimally adapted to the respective application:
Permanent fastening with stainless steel nut
The version with self-locking M8 stainless steel nut is suitable for fixed, permanent installations. It offers high vibration resistance and is ideal for permanently installed modules or structures.
Quick installation with star knob
The star knob with stainless steel thread allows tool-free assembly and disassembly. This version is perfect for applications where components need to be loosened or repositioned regularly.
Flexible solution with knurled nut
The M8 knurled nut made of stainless steel is a good compromise between a secure connection and quick handling – ideal for flexible yet secure fastenings.

Notes on load capacity & installation
The specified maximum load capacity of 1,500 daN refers to the screw fitting itself. The actual permissible load may vary depending on several factors:
- Type of airline rail used
- Installation situation and substrate of the rail
- Type of fastening used for the airline rail (screwed, glued, riveted)
- Pulling direction and load distribution
For safety-related applications, the entire system should always be considered and professionally installed.
Important material information
Caution: Please pay attention to the material combination during installation. Contact corrosion can occur, especially when in contact with ungalvanized steel. Stainless steel components are recommended for outdoor use.
