    GRK #8 1-1/2" Screws - issues?

    #8 1-1/2" screws
    sorry the title is wrong

    Using these screws.
    3/32" pre-drilled


    Any issues anyone can spot?

    I would extend the pilot bit so your pilot holes are deeper. Also if you lubricate your screws with a bit of beeswax they will drive in with half the effort.

    The first thing I see is how close together they are. Not sure where in your carcass this is but my gosh thats a lot of screws.

    Is the diameter of your countersink bit too small for the self-countersinking heads on those screws? It looks like maybe the cutters on the bottom of the head are tearing up the wall of the drilled countersink hole.
    Beranek's Law:

    It has been remarked that if one selects his own components, builds his own enclosure, and is convinced he has made a wise choice of design, then his own loudspeaker sounds better to him than does anyone else's loudspeaker. In this case, the frequency response of the loudspeaker seems to play only a minor part in forming a person's opinion.

    Does the screw really need to be deeper than this? I don't see why I should counter sink farther.

    Nope. It is just tearout from the countersink. No biggie. Going to be covered with panels

    Looks just fine as far as the screws go...but the real test is if your cabinet is square.

    All four sides are up I did not attach the back yet but all four sides are glued and screwed in dadoes

    Corner to corner is off one 16th of an inch, I am fairly certain I can fix this once I attach the back tomorrow

    I wouldn't bother with the countersink and I would just drive them until the head is just past the surface.

    GRK's cut really well.

    I run a 5" spacing when screwing backs on, and that's insane. 2" is something else entirely.
