A metal building stud having two supplemental flanges extending from at least one slot in the stud web yielding a stud with increased strength, both in compression (longitudinally) and in shear (transverse). The slotted stud also includes a plurality of indents that also enhance the stud strength both in compression and in shear. The slotted web further presents a reduced web area through which heat or sound may be conducted and slots in which insulation is received, both increasing resistance to heat and sound transfer. Slots and supplemental flanges may also be provided in the stud primary flanges. The primary flanges may include a fold back portion under a line of flexure presenting two layers through which an attaching screw must pass under that line of flexure that retains the screw in the primary flanges.
