Why use hex screws?

[pajey]

I a bit of a noob and want to know why everything used on crawler ect is hex screws, why not use normal Phillips screws? Any reason for this or.....
Thanks.

Phillips have a greater tendency to strip out and you can't place a lot of torque on Phillips if they are stuck ie stripped screw heads

Agree with above

^^X3 ive had phillips screws come on some stuff and after stripping several, i always change them out right away

Because philips screw heads have to be larger than needed in order to have a head that might not strip. Inevitably they always strip anyway.

Allen head screws are superior in every way, widely available in every conceivable style and most importantly they don't suck.

[crawlhog]

simple reason, hex screws work much better because they strip less

Thanks was just wondering.

A decent tool makes a lot of difference also. The hex head on button and countersink screws can be very shallow and strip easily.

I have found a place that supplies torx head screws which are even better than the hex head.

Also trying to fit a larger diameter screwdriver (Phillips) between stuff is a PITA, sometimes...

Any good online sites to pick up good aluminum hex hardware?

Harley sells in bulk I think. McMaster Carr , microfasteners all good places have never wanted aluminum fasteners always use stainless or black oxide

Everyone above is wrong... The real reason is that its alot more fun to clean the dirt out of them.. Real reason I like them is they can be rock rashed/smashed and 99% of the time I can still get them out.

Are there any drawbacks to using aluminum over stainless/black ox other than accelerated wear? I like the idea of tying in the fasteners to the color scheme when anodized.

Aluminum is a "soft" metal and therefore the threads are more prone to stripping, also aluminum has less torsional and sheer strength as well as less "memory" when bent... I run all titanium hardware... With aluminum just make sure to use loctite and "touch" when tightening and you will be fine....

Al fasteners are significantly weaker.

From a mechanical point of view I'd vote for Torx, which is even better than allen head, but those aren't that common... nor cheap... :(

Agreed 100%. More biting surface for the tool/fastener. The smaller allens screws on rc's seem to strip so easy. I never have had an issue with removing anything rc that is phillips. But Allens stip all of the time. I know better drivers (allen wrench's) would help. But I don't use anything high tech for phillips and they always work perfect. I have had to use a dremel to cut a strait slot and remove with a strait screw driver on tons of allen screws. Or use pliers of some sort on smaller ones that do not have the material to cut a strait slot in (example Axial beadlock screws).
