An expandable stud bracket for attachment to a board for construction of a temporary structure of support is disclosed. An embodiment of the bracket includes a receiving portion for securing the bracket to a stud, an adjustable portion opposite the receiving portion and having an extendable rod, an engagement plate attached to an end of the rod and an anchor attached to an end of the rod opposite the engagement plate and for limiting extension of the rod from the bracket, and a locking mechanism attached to the rod for preventing retraction. Optionally, a tensioning mechanism, such as a Belleville washer may be used in a key location to “self-adjust” for shrinkage or tension loss. An embodiment of the disclosed bracket may be attached between two boards to permit better access to the locking mechanism. A reusable fastener is also disclosed.
