A watertight bushing and bolt mounting assembly includes a collar portion around the bushing with a first groove within which is received an upturned flange surrounding an opening in the wall member through which the bushing extends. A resilient first seal member around the flange is pressed against the wall member, the flange or the shoulder formed therebetween to create a watertight seal around the opening when the bushing is clamped to the wall member. A clamp plate secures the bushing to the wall member by means of a watertight bolt mounting assembly which includes a nut with an annular cavity receiving an upturned lip surrounding the bolt bore. A bolt seal member is located around the lip of the bolt bore and is pressed by the nut against the wall member, the lip or the bolt shoulder formed therebetween to create a watertight seal around the bolt bore.
