The Ultimate Lightweight, No-Profile Frame Boss Filling and Sealing Solution
Natural Stainless
Thread to flush and they stay put
Precision machined from stainless steel, our blanking screws won't corrode in normal use and are available with either a natural or off-black finish. The nylon thread lock won't dry out like liquid thread locking compounds do and retains its locking ability for 3-5 installations.

These look nice and fit as they should. The blue threadlocker included is nice.The issue is removal because the screws themselves have very soft drive portion within the head, which makes me doubt the quality of the metal.If you are looking for a cheap solution to plug a few holes on your bicycle, these are a good choice but i wouldn't want to install and remove them multiple times. I had to cut a groove in one to remove it with a flat head and ended up removing them all at once after that.

Used to replace those flimsy little plastic plugs that cover up the water bottle cage, accessory bag, and fender mounts on my Trek Domane AL4 road bike. Make sure to hand tighten as much as you can and then use the proper size allen wrench (2.5mm) to gently tighten. There is no stop inside the bike frame, so just have to screw it in until flush with the frame. Otherwise, you run the risk of screwing too far in to the point it falls permanently inside the bike frame, resulting in some annoying rattling FOREVER!!!

New bikes have mounts all over. These help clean up the look of the bike without having holes all over. Fit perfect and look good.

These are the ideal way to fill the mounting bosses, not just for an unused bottle mount, but those for packs. My bike came with plastic plugs that did alright, but now and then I lost one. These are not going anywhere, and they look great too. While a bag of bottle mount screws would have done, that would mean several of them protruding in places where they don't look great. Thanks, Treske, for coming up with this solution.If you're a cyclist looking for a nicer way to close up the extra mounting locations on your bike, these are worth the expense.

Prompt, on-time delivery. The screws fit standard bottle cage blanks in frame. Easy to paint with enamel paint to colour match frame. the loctite is easily removed if you don't want it.

Love these, not for weight weenie type purposes, but because my frame came with bright silver screws for the bottle cages and to attach a rack with. The black ones work perfectly to blank out all the screw holes that I won't ever use.

I bought these to replace the existing water bottle bolts on my Cyclocross bike. They fit very nicely and keep the frame clear for shouldering.They sit below the braze-on but shouldn’t turn all the way into the frame.I would definitely recommend.

I have a Trek Checkpoint SL5. The threaded holes to attach bottles or fenders come with plastic plugs that constantly fall out. This is a permanent solution to the problem.

I like them. Wish they had a bronze color.Two pretty small qualms. One was silver while the rest were the correct color of black - which isn't really black. It's dark silver. I'm not so sure the color will last either, but maybe.One other thing, do wish they were a TOUCH longer. In 99% of cases they'll work just fine, but one of my cage bolts doubles as a bolt that holds a multitool within the frame. and this wasn't quite long enough to get that done. This isn't really star deductable.To the person thinking that they will work with bottle cages or accessories, They will most likely not. These are just a plug alternative in my eyes.EDIT: Bought another set, and there is too much locktite on it. the bolts don't want to go into the threads. It's so tight I worry I'll rip off the inner frame bolts/threads that these thread into. I'm sure I can clean them off, I still like these.

Rubber plugs in all the mount points on my gravel bike kept falling out or water leaking in. Screws mount nice and flush, keep the water out and look much better & lighter than mounting bolts.
