Leclerc Nilart Tool Fabrication

On some models of Leclerc hand looms square bolt heads are used.  Accessing these bolt heads becomes a problem when the heads are recessed.  The 12-point sockets that might work are much larger than the recesses in which these bolt heads are housed.  Likewise, the crescent wrenches that match the bolt head wind up being too broad to be able to fit in the recess as well.  Tired of improvising (this is not the first of these encounters) I found a cheap, off-brand wrench in my tool box that fits – 9/16″…
