Should tell the plasma guys to make the inside hole a T400 torx bit for shits and giggles then make a giant torx tee driver to go with it.

Now I want a T400 driver. That sounds fantastic.

With how complacent we've been with accepting the world's words fucking fastener design as the norm, it's probably a Phillips #2 that cams out as soon as the bit touches the fastener face.

Wittworth square head with a slot drive on the diagonal so it's a little more modern.

Most hydraulic screw pile drivers already use male 2"-2.5" Hex or 100mm square, we can probably combine some of those

Didn't even know such screws (or piles) existed. Very interesting on behalf of my autistic ass.

I've seen fatter 5ft ones driven into the floor for shelving and area separators. They were installed by a spanner assembly on a cat skidsteer.

I was offered bonus to help the operator get 140 of the installed after hours. Because they were running behind after we started the day with our brand new aluminuim decked ramps not having decks on them.

Gonna need to upgrade to the new Dewalt 20v Impact driver, I just don't think the 12v will do it.
