They are weaker than regular steel. Not a good choice for race cars.

Get better wrenches. Titanium is not the answer either. It is softer than stainless.

I had problems with the tips on the Assosiated wrenches being undersized and brittle. Hudy and Thorpe(MIP) are about the best you can get.

I'm in the machining field and the only thing i can say about the stainless screws is they are soft. I think the company that sell them buy cheap stainless to sell their screws for dirt cheap.

HUH? Better check that statement. Titanium is NOT softer than stainless. It is not as strong per volume, but it is MUCH harder, and it is stronger per unit of weight.

Look it up.

(Experimental avaition guy speaking here...)

stainless screws are a waste of time, too soft. people think since stainless is hard to cut and drill it makes for a tough screw, but the surface hardness of generic stainless is poor. and is a gummy metal that does not react well with tool steels (like wrench tips) So we strip strip strip away. You would be better with a good grade aluminum; yeah, really.

Carbon content is what makes steel hard, and stainless has close to none of that carbon stuff. and carbon steels grip a tool steel the best, a hard aluminum maybe better?

there are some grades of stainless that can approach the hardness of carbon steels but would still most likely have a problem being pressed up against a tool steel.

Titanium is all over the map. there are so many alloys out there (some 40 grades!) its hard to know what a screw vender is using. but if you want corrosion resistance there is no better.

A good aluminum screw (7000 alloys) are great when used appropriately. you can really lighten things up using them in lesser stressed areas like the radio tray, or body mounts.

So, ya get some 12.9 grade steel screws. It still is the most effective option.

When I buy screws for spare I buy in bulk at fastener express. They will have everything you need.

Stainless is a bad alloy for rc fasteners. If you have ever tried to drill, tap,thread, or cut stainless it is harder to cut than carbon steel, but for some reason or the other it is to soft for the tools we use to wrench on our cars with. I once had all ss fasteners on my 1/8 buggy and ended up stripping them all out. It wasnt from bad tools either, i use the mip's which I feel are the best but the screw would strip from trying to break loose. Stick with 12.9 alloy steel.
