Yes these casters will be perfect for laminate floors as they are non marring rubber wheels.
It ultimately will depend on how much weight you are planning on sitting on top of the casters. You can use like 1/4" lag screws which will do just fine, but if you are planning on loading quite a bit of weight on top of these I would go with nuts and bolts.
Yes they would work just fine. You would not be anywhere near the maximum weight rating of the casters.
not the ones i bought in port huron, mi
2-5/16" x 2-3/4" - the 2-3/4" inch sides has a slight curve inward that recedes to 2-1/2" at the center of the side. the corners have a 1/4" radius edge. 1/16" in. thick plate. the screw holes are 5/16" diameter. Too big for regular drywall screws to hold to anything without at least a washer. (and no bolts included with the units that i bought in port huron, mi)
