A screw lock rivet for use in adjustably securing a riveted member to a companion member, such as a supporting bracket, has a rivet shank portion for pre-riveting to the member to be attached, and an integrally formed head terminating in a nut portion, the underside of which head is formed with diametrically-opposed, axially outwardly-projecting arcuate elevating ramp portions and a central shank base portion ovoid in transverse cross-sectional shape and coaxial with the rivet schank portion. The bracket or other companion member to be adjustably attached to is provided with an elongated adjustment slot communicating with an enlarged opening for reception of the rivet head and to permit the sliding therealong of the screw lock rivet shank base portion, the relative dimensions between the bracket slot width and thickness, and the size and shape of the rivet shank base portion, being such that upon turning of the screw lock rivet, the elevating ramp portion will be constrained to clampingly ride up upon surface portions of the bracket adjacent to the slot, while at the same time causing radially increasing peripheral arcuate wall portions of the ovoid shank base portion to wedge transversely within the slot at an adjusted position therealong.
