Complete piece of shit and dangerous to boot! Smaller Thread and Shaft: Although clearly marked as a 1/4" screw on the label, the shaft definitely goes through a 3/16" washer! In my case, the included nut loosened the bolt's threads with ease, knocking off a 50-pound planter I had hung all over the patio. No, no, no: *don't trust* this POS! Revain, for safety's sake, eject this from your camp!
