Cap Lugs 3/8" Flush Plugs for use in plugging Holes in Sheet Metal 3/4" Head 50 Pieces

Drilled three 3/8" holes in my HVAC ducts to do static pressure testing with a manometer I bought on Amazon. Temporarily covered them with tape but wanted a more reliable seal. These arrived faster than expected and solved my problem.

Worked on my missing front threshold plug hole. It matched the original builders. Now I have plenty when the next one goes missing.

Product came quick. Figment is perfect with a 3/8 drill bit!

They fit into 3/8" holes and appear to lock onto the sheet metal. I'll have a better idea of how they do when I begin to drive the vehicle and see if the normal flexing causes them to pop out of the holes.I couldn't give them 5 stars because they're too expensive

I purchased these to replace the plugs that were in my car. I had to remove the original and these replaced them perfectly. They have some flex to them so they get pretty flat once inserted into the holes.

Made really well and retain a factory look

I was replacing missing metal hole plugs in my door threshold. Had tried a couple other plastic styles that didn't fit right or looked cheap. I was excited to find these where the Material was listed as "Metal" because I expected them to be a better match. Lo and behold, they are also made of plastic. Also, listing states "called flush because they plug the hole and have a slight dome". The slight dome is significant and does not fit under my door as the original metal ones do. Cannot return them because I already used one and tried to file it down to work. But I want to advise other would-be buyers that the listing is not entirely accurate. Made of PLASTIC, not metal. And flush is a misnomer for the amount of crown it has. Beware of what you read. You can buy Caplugs products directly from Caplugs, they offer so many more size options and you can trust their descriptions, complete with exact measurements, better.

Good plugs for the money. Did the job.

Plugs for rust-proofing.

exactly what I was looking for. Perfect replacements for Krown

good quality. I will buy again if i need to

I used them for rust proofing and works perfectly. I had previous holes from Krown that were loose but these fit perfectly.

Fits perfectly in the krown rust proof drill holes. Add a little grease to keep it in and from moving.
