SS Button head screws
Hi. Does anyone know of a complete Screw kit for my new Helibug T-700 gasser, that is coming this wk. and where to get them. A friend replaced all of his with SS allen button head screws tired of them breaking on my T-600. Thanks ED.

I'm not dead sure but i think SS bolts on a gasser will try and loosen up,but like i say i'm for sure. Just use good locktite.

That is interesting because SS screws are much weaker than a typical Allen head (carbon) screw.Ace

Mcmastercarr has an excellent selection and they are cheap. Most of their metric hdw is USA made. Around $5 per 100 pieces.

Unless it had a military specification I would find that very hard to belive these days. It is not even a given if it does have a military spec.

I don't think these are commonly available bolts, they are shouldered with button head hex slots.

the ones used to mount/align the bearing blocks are the ones that strip the heads.

they manage to get about $1 per screw for the s/s versions

How old are they? Just because you have them now doesn't mean you will get them on the next order. MM carr is an industrial supply house. Their margins are affected by what they pay for the supplies. Try and get an origin certificate on that hardware. I am not trying to hurt your feelings but that "made in the USA" could mean the box.

Hi Flying Fossil

Just remember, that if you use loctite 242 medium,
you will only get a littel more than 25% threadlocking
power when using it on SS, and that`s after a cure time
of 24 hours.

I`m not aware of any loctite threadlock that have been
made specially for SS.

You can download a PDF with the loctite 242 tech-spec
https://tds.us.henkel.com//NA/UT/HN...2571870000D60D/$File/242-EN.pdf

two weeks old, quality is very good, don't need certs not building a rocket or anything that would require traceability...lmao!
Dealt with McMaster for years, very pleased in everything I get. Beats the heck out of paying .50+ for two fasteners just because they have heli xx part number on them.

Camcar is the manufacturer, Lot #298393, packaged by NJ, made in the USA. And a link to the manufacturer as well.

I would bet any day of the week that these fasteners surpass most of the crap that comes in a heli kit, especially Align.

Having a tough day? lmao...
Guy needed hardware, I pointed him to a good cheap source of decent quality. No more no less. Package said hdw was made in the USA, it did not say China. I was impressed. It works for me.
Is it really USA made? Who the hell knows or cares. When I worked in the film industry every box of 316 stainless hardware we got went right into the passivation (nitric acid) tank, all of it. We lost 10% on average. It weighed 50 lbs when it went in and 40 something when it came out. So one really never knows that I agree with. But for Joe Schmoe modeler, at $5 per 100, the savings is great.

Well if you want to get technical that is 20%.

Actually my real concern is going to stainless in the first place. If the heat treatment is correct on the carbon screws they will be stronger than the stainless. The other disadvantage is that loc-tite doesn't really work on stainless which is probably good because you will just round the head off trying to remove the screw if it did work. Bad though that the screws come loose. So you trade one problem for another.
