Screws & nuts for airline rails
Countersunk screws are mainly used for installation. These allow for a flush finish so that airline fittings and accessories can be used without restrictions. Our stainless steel screws are particularly popular because they are corrosion-resistant and perfect for outdoor use.
✔ Standard and heavy-duty profiles → Fastening with M6 countersunk screws
✔ Light profiles → Fastening with M5 countersunk screws
✔ Strength 10.9 recommended → for maximum load capacity
✔ Combine with washers & self-locking nuts
❌ Not recommended: self-tapping screws, as they loosen over time.
Rivet nuts – the smart solution for thin materials
If through nuts cannot be used, rivet nuts offer a stable alternative. Especially with sandwich panels or thin-walled car body parts, they create firm threaded points and enable secure mounting of airline rails – ideal for camper conversions or transport vehicles.
Glue airline rails instead of drilling
Adhesive bonding is a particularly clean solution. With Sikaflex 554, we offer you a structural adhesive that has been specially developed for vehicle and caravan construction.
✔ Easy to use without drilling
✔ Suitable for aluminum, GRP, wood, and painted surfaces
✔ Even force distribution and sealing
✔ Extremely high adhesive strength with proper pre-treatment (cleaning and primer)
Tip: An integrated adhesive bead on many airline rails provides additional hold.

Frequently asked questions about fastening materials for airline rails
The right fastening materials are crucial for the secure, durable installation of airline rails. Here we answer the most important questions about screws, nuts, rivet nuts, as well as bonding and surface preparation.
Which screws are recommended for airline rails?
Countersunk screws are suitable for most applications: M6 for standard and high-strength profiles, M5 for light profiles. Use 10.9 screws or A2-70 stainless steel for outdoor areas. Use suitable washers and self-locking nuts to prevent loosening due to vibration.
Which nuts, washers, and rivet nuts should I use?
Self-locking nuts and flat washers are recommended for permanent connections. Rivnut nuts are ideal for thin sheets or hard-to-reach areas, as they create a stable thread. A2 stainless steel is recommended for outdoor use.
Can I use self-tapping screws?
No. Self-tapping screws can loosen under load and vibration. Instead, use countersunk or pan head screws in combination with nuts or rivet nuts for permanently stable connections.
Can airline rails also be glued instead of screwed?
Yes—gluing is particularly useful for sandwich panels or sensitive surfaces. Construction adhesive distributes forces over a large area and reduces drilling. For maximum safety, a combination of screws and glue is recommended.
How do I properly prepare the surface before gluing?
Thoroughly degrease surfaces (e.g., with acetone), remove loose particles, and lightly roughen if necessary. A Sika primer is recommended for Sikaflex 554. Observe the curing times and manufacturer's instructions.
Which cleaning agents are suitable for surface preparation?
Use solvent-based cleaners such as acetone or Sika Cleaner. Household cleaners or acidic agents are not suitable. Wear gloves and ensure good ventilation.
Why is Sikaflex 554 often recommended?
Sikaflex 554 adheres excellently to aluminum, GRP, wood, and painted surfaces. It forms a durable, weather-resistant bond and is therefore widely used in vehicle and caravan construction.
