At work, we use 9/16" sockets to tighten these recessed bolts in an air chuck. The machined width on them is such that only a few brands will fit, mostly thin walled sockets and cheaper brands like Husky.
We have some Proto that just don't fit at 0.8100".
Husky measures at 0.7680".
Does anyone know of a currently available standard 9/16" 6pt 3/8" drive socket with overall diameter less than 0.800"?
