Washington Lazy Susan Components Round Shelf Bracket

Seems substantial enough but why on earth would the manufacturer, made in USA even, have a square headed 1/4" bolt to attach it to the post when it could be tightened much better with a regular Phillips screw driver or a bolt with a 7/16" socket wrench? I replaced the square head bolts with 1/4" bolts with and tightened with a 7/16" socket wrench. Worked great.

Nice bit of kit. The only thing I would do differently is replace the existing set screws with ones that are cut with a slot to work with a flat blade screwdriver. The ones that come with these supports are just a square head, and turning that thing in the tight confines of a lazy susan cabinet is no fun.
