Do not force a nut and washer tight against a sloped face. Square the bearing surface or use an approved swivel/angled support so the rod hangs plumb.
['A hanger rod wants to pull straight down. If the anchor seat is on a sloped beam face, tightening the hardware can bend the rod and side-load the anchor.', 'Check whether the support can be moved to a flat substrate. If not, the usual fix is an approved bevel washer, shim plate, swivel insert, or engineered bracket that keeps the load vertical.']
