A hand rail assembly having a wood hand rail is supported on a plurality of brackets that can be premounted onto a wall. The brackets include a rail bolt threadable relative to the mounted portion of the bracket. The rail bolt has a T-shaped head that fits into a groove opening on the rail that opens to recessed groove portions. The heads of the rail bolts are arranged so that they are parallel to the groove opening, and then when the rail has been placed with the heads inside the groove opening, the rail bolts are rotated so the head fits into a recessed portions of the groove to hold the rail on the rail bolt. A nut is then used for clamping the head in position on the rail for mounting the rail securely. The rail bolt has flat spots so that a tool can be used to manipulate the rail bolt.
