Cowling & Inspection Plate Screws
I offer three styles of cowling screws: Plain (no washer),
one with protective plastic washer and one with a wide non-removable
stainless steel washer.
The plain type is most common, but is known to scrape away the paint on your sheet metal when you tighten it. The plastic washer helps prevent that and does a great job, but some people may find the large plastic washer unsightly. The last option is the large stainless washer (which cannot be removed) because it hides the most existing damage and sits nice, low and flush. This is the style currently on my plane.
These screws are similar to Cessna Part Number S-1021Z-8-8 (aka AN530-8R8). They are found on countless Cessna aircraft on the cowling and inspection plates. They arrive from the manufacturer with a shiny stainless finish. As you know, this rarely matches your aircraft's exterior paint.
I am currently powder coating the heads of these screws to match (or closely match) your plane's paint. The most common color is white. I also offer blue, red and many other colors.
They are powdered in-house and shipped to you separate from each other so that they don't bump and rub around in transit.
is powder coating?
close will the color match?
I send you my screws (or plates) to be powdered?
If you have any qualms about the legality of installing these screws on your cowl, inspection plates or anywhere else these part numbers are called for, you should consult with your A&P first.
