Locking against a pin, this box lock measures 45 x 21mm and 7.9mm thick, a perfect size for jewellery boxes. It comes with brass plated pin striker plate, key and 13.3mm diameter escutcheon that needs a 7/16in hole drilled to seat plus screws. It does not come with the standard #2x8 screws - we sell these in packs of 50 on our website, or you might already have some in a drawer somewhere!
