I am looking for an M3x3mm and an M3x10mm titanium button head torx machine screw that ships within the US. I feel like I have looked everywhere and I can't seem to find any. Does anyone have any recommendations on where to look?

Amain Hobbies, Tower Hobbies, or any drone store should have metric screws that size.

Thank you. I will be sure to check those out.
Also, I accidentally typed M2 instead of M3 earlier, in case that makes any difference in your recommendations.
 
Lunsford Racing has them, but they're gonna be hex drive instead of torx...not much torx use in the R/C industry.

Thank you. I definitely would have preferred torx, but I think these will actually work really well!

They are EXTREMELY well made, but titanium is soft...use a high quality tight fitting driver and you'll have no problems👍
 
I checked my usual sources, and the closest I found are at McMaster-carr.com

18-8 stainless steel, button head, T10 torx drive

M3x4mm 100 count $7.39

M3x10mm 100 count $4.48

They're not titanium, and you might have to shorten the M3x4mm a little, but they're torx. And you'd have plenty left over.

They also sell individual "high strength" A286 stainless steel button head T10 torx screws-

M3x5mm 1 for $3.55

M3x10mm 1 for $4.54

Thanks. I'll take a look at those!
 
I have to ask why they have to be US sourced.Anyways I found the sizes on that AliX site that I usually purchase from. I can vouch that these are all quality, well priced and importantly not at all soft.

I just don't like dealing with importing items, customs always takes forever to process items or they loose them so I find it easier to buy items that are already in the US. Thanks, I take a look at them.
 
I personally try not to use stainless screws as they are a softer steel and can strip or break easier. Most stainless screws are decorative and not that strong.
 
The M3 18-8 SS screws I mentioned are rated at a tensile strength of 100,000 psi.

The M3 A286 SS screws are rated at a tensile strength of 140,000 psi.

That's a lot more than "decorative", and I'm sure they're plenty strong enough not to break, either during tightening, or under normal use of the knife.

M3 titanium screws (hex drive, also sold by McMaster-carr) are rated at a tensile strength of 130,000 psi.

Glad to see there are sources for high quality stainless. Most of the stuff I've used is hobby and/or hardware store variety. The kind of stores you'd normally get your stuff from.
 
I just wanted to note the only titanium screws that I've broken were the ones included in a pair of flytanium handle scales.Where attaching two identical pocket clip screws and having them both break with extremely surprising ease,it doesn't take a genius to know that something is extremely wrong.
