Both lug bores are line-bored in one pass, so their coaxiality is what lets the pin slide in by hand rather than the lug spacing being set by guesswork.
The base holes sit clear of the lug roots so bolt torque does not pull the lugs out of line.
Double-Lug Hinge Mount
Both lug bores line-bored in one pass so the pin slides in by hand; base holes sit clear of the lug roots so bolt torque leaves the ears square.
