Cowling Fastener Kits

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.

Typical IPC (illustrated parts catalog) and maintenance manuals are not accurate when compared with what is actually in the aircraft. That's why Quick Release Fasteners kits have been refined over many years with research on the flight line and hands on field experience. Our kits are Guaranteed to fit your particular year, model and serial number aircraft the first time, right out of the box which saves you time and money!

See a competitor’s kit that has extra, various length fasteners and hardware to hopefully make things fit right? Guess what….. you pay extra for that. Save yourself some time and money with a Genuine Quick Release Fasteners kit!
