Are these dual drilled on the bottom for 1/4-20 or 3/8-16 thread attachments so I could use both screws with my Sunwayfoto quick plates for extra strength and prevent rotating?
EDIT, I found the info and looks like it is, do the holes have steel thread inserts, does anyone have a picture of the bottom they can post?
Thanks
