I used it to support the belt for the prevention of the fall of a large speaker. I think that it was good that polishing of the surface finish was polite a little because it can be attached to the room of the home (it looks like a cheesy plated product). There seems to be no problem at all for strength and shape. Although there is no problem with not having a flat head screw, it was not possible to prepare the screw beforehand because the dimensions of the countersink diameters are not on (not on the manufacturer's page). Please improve.
