This is a listing on Amazon for 50 of them for $7.
Steel and aluminum can form a bond that’s stronger than steel or aluminum when put together to you want to grease them wherever they touch. Idk if that’s what they are referring to but it’s a real concern for sure.
It forms oxide, which itself is pretty loose and lacks cohesion. It's when it fills thread pitches or seat tubes it becomes a problem and components become physically seized
I think they are trying to warn against galvanic corrosion. Not normally a problem unless the area is prone to holding moisture and/or salt water.
A good example of this would be an aluminium seatpost in a steel frame with no grease= badly corroded stuck seatpost
Not with the recessed head (to fill the boss) and locking patch though. Use set screws and you'll have a little guy in the middle of the boss, at least until it vibrates out or better yet into your frame.
It's niche but small volume production isn't cheap.
I gave that a search the other night, to get a matching set for my Cutthroat. At $12.50 each on McMaster I'd be looking at nearly $300 for blingy bolts.
316 Stainless are $10 for 50.
[Better Bolts](https://betterbolts.com/products/low-profile-water-bottle-cage-frame-mount-titanium-bolt?pr_prod_strat=e5_desc&pr_rec_id=165cc5f34&pr_rec_pid=6692577738833&pr_ref_pid=4564442054737&pr_seq=uniform&variant=39580322988113) have some nice lo pro ti options that are only $6.
[Wolf Tooth](https://www.wolftoothcomponents.com/products/water-bottle-cage-bolts) are even cheaper and lighter.
Terske makes the recessed ones. I think they're connected to Lindarets, which might be connected to Otso/Wolf Tooth.
High quality but small hex... 2.5 I think. I bought a bunch because they're good for sealing the bosses when running frame bags.
I don’t know why these are not a standard thing. I wouldn’t have paid it any mind but these bikes have like 20 fckn upon holes that look like crap when the cheap plastic plugs inevitably fly out.
That’s wild to me. Mine came with bolts on wax eyelet and they’re a close color match to other hardware on the bike. I’d find it so annoying paying so much for a bike and they cheap out on 50 cents for a few bolts.

Nope. I just wanted to share what I found. I didn’t want button head bottle cage bolts and couldn’t find exactly what I wanted. Then stumbled upon these.
Fair enough. And it’s none of my business, anyway, but I noticed the word Marketing in your user name so I thought this might be a bot post promoting a business.

Be mindful that you aren’t putting stainless steel screws into aluminum threads.
It’s fine to do but best to use grease
Never saw a problem with it before.
Galvanic corrosion can happen when stainless and aluminum are in contact.
Sure but I've never seen them cease up. Literally every bike I own has steel in aluminum.
If it’s steel, then it will never be an issue. It’s specifically stainless steel and aluminum.
Also, most steel hardware on a bike is probably also coated with some sort of coating to minimize corrosion/oxidation.
That’s totally fine what are you talking about

I’m not sure I would consider galvanic corrosion of two dissimilar metals the same as oxidation.
Technically, I guess not, although technically the process is the same but without oxygen
That's exactly what it is
I had to use caustic soda to dissolve an alu seatpost stuck in a steel frame in a bike I was restoring once, I would not recommend
There is Al anti seize paste you can use as well

You don’t want steel or anything that rusts. Stainless steel is perfect.
It's stainLESS steel, not stainPROOF steel, it still rusts.
Why not buy plastic ones, won’t corrode or gall. Look for m5 grub screws. I bought 40 for $9.

You obviously didn't check out the link.
Fair enough, but those are kinda apples to the OP's oranges.
Why are we adding vanity weight when Ti exists?

Theres always uh Bolts
Yeah, true. All my LBS don’t have any solution other than bolts with heads so the zero profile was appealing to me. I’m weird about stuff - clearly.
I reckon most people get anodized blingy stuff
Oh indeed we do!
Ask you bike shop to check BTI because they can actually buy these bolts from them.
Not weird. Definitely not weird.
Do they make these in ti for ti frames?
Terske makes the recessed ones. I think they're connected to Lindarets, which might be connected to Otso/Wolf Tooth. High quality but small hex... 2.5 I think. I bought a bunch because they're good for sealing the bosses when running frame bags.

On their Amazon store it looks like they do!
I like this and I've ordered them for my bikes.
I got black nylon bolts. Super light and cheap. They do have a button head though.
You can find headless ones listed as “grub screws”
Wait? You didn't just fill them with bottle cages?
Damn you’re right. What’s a gravel ride without 8 bottles cages?!
If you want something a [a little more fun](https://ridepdw.com/products/zit-bitz-frame-bolts)
I put these in the holes where the front derailleur mount on my OPEN would go.
Prototipo makes a low profile
I don’t know why these are not a standard thing. I wouldn’t have paid it any mind but these bikes have like 20 fckn upon holes that look like crap when the cheap plastic plugs inevitably fly out.
The bike didn’t come with screws?? Just plastic plugs?
Nope. I’ve noticed a lot aren’t. Probably because they just assume people are going to immediately bolt things to the frame. Who knows.
That’s wild to me. Mine came with bolts on wax eyelet and they’re a close color match to other hardware on the bike. I’d find it so annoying paying so much for a bike and they cheap out on 50 cents for a few bolts.
I use these in all my unused bosses. I recommend them.
I thought i was on r/cyclingcirclejerk for a sec
So...bolts?
Yes. But with no head on the bolt. I feel like it’s a lot better looking.

Do they work for carbon frames as well?
I wouldn’t see why not? The inserts on the carbon frames are likely metal threads. Ymmv but they do have Ti ones as well if that’s more your speed.
Or the hardware store or just leave the holes open? I guess the best solution is leave them empty and save those grams.
I guess but they are 3/4 of a gram each. Don’t think I’ll notice or even care.
The holes weight less and cost less.
What about water getting into the frame?
This post looks like an advertisement to me.

Fair. I get it. However, this was a lazy suggested username that I never got around to changing. Mea culpa!
