Cheaper than OEM replacements
Had some of the caps on the windshield bolts of my XJ900 that were missing. If you can even find OEM replacements, just a couple of them cost as much as this whole set. This set has the exact size I needed, with plenty of spares, and has a bunch of other sizes should I need them in the future. The caps fit well and look very close to the originals. They are tight enough that they should stay put.

Fit perfectly
Ordered this as my new patio set was missing caps for the bolts. This has an assortment of sizes, and one size fit perfectly. They are made of hard plastic. Durable and fit tight. And now I have the rest to hold onto when they are needed.

Metric Black Nut Covers
If you are looking for cosmetic nut covers, I used them in a motorcycle that is metric sized, these are great. The price is reasonable and the quality is good. Perfect to cover stainless nuts and bolt ends on a black motorcycle.

Perfect fit
I bought this to cover some screw heads in a bench I made. They fit so perfectly that I didn’t even bother with glue.

Decent assortment
Unfortunately, none from the pack the patio set I purchased them for. Rather than returning, I went to one of my favorite go-to hacks. Yes, duct tape is great for many things, but I find myself using rubber cement even more. I brushed in a good good glob of rubber cement to the cap size above what I needed and pushed them into place. After a few months outside in Sun and rain, the caps are in place and I'm assuming the rubber cement has kept the bolts and nuts from rusting while while letting the caps provide their aesthetic improvements.
