Cowl Fastener Studs Needed

alanmcraig

I'm New Here
Need help finding replacement studs for my cowl fasteners. My RV-9A was build by Brian Woods in 2004 and uses a unique cowl fastener (not the standard camloc or skybolt type). Any help finding a source for the studs or suggestions for a possible supply or supplier would be very appreciated. I have checked sources at EAA Osh and all the usual aircraft material suppliers. I suspect this may be a fastener type used on Commercial aircraft since I understand the builder worked for United Airlines. The fastener receptacle has 4R41-1 Camloc stamped on the back and I believe the stud is labeled 4S4-6. Photos of the stud and receptacle attached. Please contact Alan Craig 408-309-1542, [email protected]
Update 2/24/2024 Found and purchased 6 from Foreland Aviation in South Africa. Parts search service ILS was very helpful and provided a listing of all their participating suppliers for aviation hardware that had my parts in stock. Many calls and emails later I got a confirmation from Foreland with photos and RPQ that showed the spring screw fastener I needed. Interesting example how experimental homebuilt aircraft can truly be built with unique parts.
