A surface bolt adapted to be mounted on an inner or outer surface of a closure member, such as a door or window, the bolt being slidable in guides between positions into and out of engagement with a keeper. One of the guides is provided with means to receive the bow of a padlock in two positions, in one position to prevent unlocking of the bolt or, in the other position to prevent locking of the bolt. The bolt may have a recess extending across its outer surface, positioned and dimensioned to be engaged by one of the guides in the locking position of the bolt and to be resiliently and releasably held in such engaged position by a spring.
