That looks correct and had to be as Losmandy uses US Standard thread here. ?If other tools were used this might gall the bolt edges. ?Assuming a G11 RA, the back Altitude Screw plate secures with two bolts using the same Allen Key. ?Check the tool. ?That bolt should take no more than snugging to provide the needed clamping force for Gemini-2 (more than the short end but much less than hand torque of the long end of an Allen Wrench).?
Assuming light galling, I'd try initially using a ball-end 3/16 key aligned and lightly tapped into place past the rough edges. ?This size had to have been selected because the mount receiver might be left out in the weather with the aluminum threads. ?Be sure to replace the bolt in kind.
