When I read the note I was thinking, actually recessed, when the bolt is let into a hex shaped hole that completely fits a bolt head.
But.......
Looks like plenty of clearance for a thinwall deep socket to me. Any auto parts or good hardware will have one to go on your ratchet, since it sounds like you do have basic tools.
Of course, us old tool nuts will prefer an older vintage ratchet and socket.
Feels good, looks good, works good, whats not to love?
Modern tools have little to no soul. You don't even need to look, you feel it right in your hand.
One feels like a reliable soft old friend anxious to help, and the other a jaggety nervous stranger.
This is what Tool Talk is really all about.
