    Product page link errors out... looks like it got up and moved.

    Looks like a useful bracket tho. I might have to get some of those.

    Hey guys, can anyone tell me if a M3 screw fits on this angle bracket? Even if it takes a little pushing... Since a 4-40 screw have a diameter of 2.845mm I guess it wouldn't be a problem. Did anyone tried it before? Thanks!

    Would these be good conductors to use as a switch plate?

    Dimension from outside vertical edge to the center of the horizontal hole? Symmetrical?

    Would love to have slightly bigger ones, say 0.5" length or so. These are so tiny you can barely fit two screw heads on the inner side. If I want to use a nut on the inner side, it's practically impossible...

    What is the brackets thickness?
