Ultrex Head Screw

Hi all

Would any of you happen to know the Size, Length, and tread type for the Hex screw that holds the head unit on the Ultrex arm?

I had a locking screw with a knob on mine and it fell off into the lake. I need to find the right size so I can replace the stock Screw.

Thanks

Go on Minnkota parts page. My guess 3/8 16 thread, 1/4” Allen head, 2” long..just guessing

It's a 5/16 - 18 with a 1/4 Allen head. Not sure of the length

Thank You all!
