Ya'll triggering my autism. "Smelting" is NOT a fancy word for "melting metal". It specifically refers to extracting metals from ore, and nothing else.

Do not open stepper motors. You will partially demagnetize the rotor, tanking their performance.

>When it comes to torque transfer

For fuck's sake, why do people keep thinking this? It's the WORST at high torque because there's much less contact between the driver and screw head, meaning less material has to deform for the screw to give. It doesn't matter that it has to give MORE for the head to slip, because once it fails, it stops providing any structural integrity. Its only saving grace is that the slot can go to the very edge of the screw, forming a longer lever arm to the middle of the head. But that isn't nearly enough to make up for for the substantial increase in useful contact area every other driver type.

The absolute best design (in semi-common use) for high torque is exterior hex. A large amount of material needs to fail before the screw strips, and the mating surfaces are as far away as possible from the center of the screw. There is the slight downside of requiring a fairly close fit to avoid rounding over, but it's not like that's unique to hex, anyway.

The only one better than exterior hex is exterior spline. But, of course, those are well into "specialty" screw territory, and with a price to boot.

I'd take Phillips over slotted any day, and THAT'S saying something. At least those can self-center.
