I went to the local Home Depot. I found stainless screws for my Ham-M 
rotator without a problem. These were not hex head, but slotted. I 
think they were 1/4", but I don't remember.

It shouldn't be a problem to find mounting screws for a rotator at any 
hardware store. I'd get stainless. I also used a stainless split and 
flat washer. I used a flat washer on each side of the rotator plate -- 
which helps to keep a small space between the rotator and the plate.

My rotator has been up 3.5 years with no slippage in any of the screws. 
(Be sure to check your mounting hardware in your annual tower 
inspection -- thermal cycling can work tight hardware loose)
