Recently acquired a used Solix 12 and a Mega 360 (also used). In process of installing them both now. The straight bracket that holds the Mega 360 has two holes in which go two allen wrench hex socket screws 9which were not included with the bracket). The questions I have, are these two screws 10-32 x 5/8" and are they a fine thread? Thanks for any and all replies. Hope all have had a Merry Christmas and that the New Year is good to us all.
