LGEGE - 3/8", 25 Pcs Black Screw Thread Protectors

I got these today along with my f103 and f106 (I doubt I am allowed to day the brand name of oil drain valve) and they fit great. I was worried they might slide off between oil changes but they are snug as can be.

I bought these to use on the bolt/charging handles on my rifles, so they don't scratch neighboring rifles in my safe. Some fit a little snug, some a little loose, but on average they work quite well. I'm sure they could be found cheaper at a parts or hardware store, but I suppose Amazon convenience is worth a few bucks.

I am a Ham Radio Operator, using these to cover the Aluminum Element Tips of my Ham Radio Antenna. The Antenna I am building is a CS3-JK, and the fit perfectly. This will keep the bugs out hopefully for a number of years.

I used these to cover the ends of some 3/8" aluminum tubing on an amateur radio antenna.They were exactly what I needed. Nice snug fit. They'll keep the bugs, dirt , and rain out of my 20M4DX.

Perfect size to cover patio table skinny legs. I had spray painted them and worried it would leave marks on deck. It worked well!

I picked up a used play set and had to get some new bolts to put it together that were too long. I cut the ends of the bolts off but wanted something to cover the sharp edges. These worked great for that! They were exactly what I needed, fit perfect and I would buy them again!

I received the screw protectors very promptly. Unfortunately, they were much larger than I expected. It’s not worth the cost of returning them so I will find a use for them.

If this is what you are looking for, you’ll get exactly that. There’s some flexibility too which is nice as I had one anchor closer to the nut than others. Still capped nicely.
