Need opinions on screw types from someone with experience (lemmings.world)

I am building some simple "pallets" out of 4x4 lumber to ship some machines.

The plan is to screw the feet of the machines to the top of 8 foot long 4x4s, and then to screw shorter 4x4s, probably about 4 feet, to the top of them as crossbars to move the machines with pallet jacks. Basically, I'd have a rectangle 8 feet long by 4 feet wide with the weight being supported from above by the crossbars. I'm not sure how much the machines weigh, but as a guesstimate, I'd put them at about 600 lbs each.

My question is what type and length of screws should I be using for this? I may double up on the cross bars if it doesn't feel strong enough to safely carry the weight. Given I'm using 4x4s, I'll have about 7" of wood to work with, I imagine 6 inches would be a minimum length, but I don't know if I need some thicker screws, in which case I might need to drill some pilot holes.

Thanks for the help

I get that 4x4 might be overkill, but the feet on these machines are 3.5" wide, so I can't realistically put them on the narrow end of a 2x4. I'm also ok with overkill since I'm shipping 4 machines worth at least 100k each.

I also can't lift the pallet width-wise since it needs to get through a door that is exactly 8 feet wide. We'll be moving it slowly with two jacks, or a jack and some kind of dolly for the other end.

I'm not paying for it, so I don't care about the cost. I'm trying to get the simplest solution. If I do it with 2x4, then I need cross bars under the feet, and I need to attach the bottoms as well, and I need a lot more measuring and cutting to get the job done.

I see why you choose that method then. I only need to build for forklifts going through large bay doors, so I'm afraid I can't give good advice for the constraints you have.
