    Watch out, it’s a little loud at the end. sorry.

    It took a bunch of force to get the second one in. It clearly wasn’t as sharp as the first one. These aren’t new stock, but they are SFS 12-24 Impax 5 (SD5) 1/4″ vs Buildex unknown model 5/16″. Both screws were subsequently and successfully re-used.

    I was installing wire hangers onto a trailer and wanted to put a hang point on what happened to be the very thickest portion of the trailer (where the tongue triangle welds to the rectangular portion of the frame.

    Bring on yee industrialization of society!
