Cowling Fastener Kits - Original Equipment, Stainless Replacement
Cowling Fastener Kits - Original Equipment, Stainless Replacement

These stainless cowling kits replace the old, worn and rusted quarter turn fasteners originally installed on your aircraft with top quality, FAA approved stainless replacement fasteners!

Save yourself some time and money with a Genuine MilSpec kit!

Typical IPC (illustrated parts catalog) and maintenance manuals are not accurate when compared with what is actually in the aircraft. That's why MilSpec kits have been refined over many years with research and field experience. Our kits will  fit your particular year, model and serial number aircraft the first time, right out of the box!  We Guarantee It. 

  • Polished and Passivated Stainless Fasteners with a Finish so Bright and Shiny you will need your Sunglasses!
  • Kits for Twin Engine Aircraft are for Both Engines.
  • Kits are Available with Slotted Head or Phillips (cross recess) Head Studs. Both head styles feature our proprietary materials and machining methods which insure they will not strip out or gall, even when over torqued giving you many years of unmatched service!
  • Slotted head Kits Use Our Special Collared Slot to Prevent the Screwdriver from Slipping Out and Damaging the Paint
  • Optional Fasteners for Battery box, Radome, etc. Are Also in Stock. They are Listed in the Options Section at the Top of Each Manufacturer's Page.

Don't forget about installation tooling. If you need guidance as to which tools may be required for your particular selection, please contact us and we will let you know. We keep all installation tools in stock for purchase or rental.

* Please Note: These kits do not include exterior screws, fuel tank screws or structural hardware. These items can be found on our main products page. Also, receptacles are not included as they usually do not require replacement. But if you need some, we have them in stock. Please order them separately or just contact us for help if you are not sure which ones you need.
