May has well have some of these in your stock as perhaps dropping one never to be seen again means you need another.

40G26-1 Camloc Stainless Steel Retain Ring

September 30, 2025

These are a shorter version of the OS grommet. I have a collection of all sizes as I regard the install process as more trial and error, at least for me. One also needs a collection of the various stud lengths.

4002-Hs Camloc Grommet

September 30, 2025

These are what I call the longest grommets. My cowling has a sheet metal repair that doubles the thickness, hence a longer grommet was required to get all to hold together.

Q&A

Please note, Aircraft Spruce ®'s personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician.

Q: What are the differences between the flush grommet & the plus flush grommet & the wide area grommet?

A flush grommet requires the material be slightly dimpled, or countersunk, so the top of the grommet sits flush with the material. Plus flush does not require a dimple, or countersink, and sits on the material and is slightly rounded. The O.D. of the wide area grommet is .876", and the others are .625" O.D..

Q: When the grid says max panel thickness, is that including the washer and ring? Or just the panel itself? (ie. fiberglass cowling)

It is just the panel thickness itself.

Q: Does the 4002 grommet come with snap ring?

The snap ring does not come with the grommet.

Q: Does the 4002-GS and 4002-NS grommets come with the snap ring?

No, the snap ring will need to be ordered separately.

Q: Is the price per snap ring, or per pack?

These are priced and sold individually.

Q: Can you confirm max panel thickness for 4002-N3 grommet is .072 and not .128 as shown?

Max panel thickness is .072.
