ABSTRACT:
A screw retainer comprises a substantially flat clip having a central resilient tang engaged by a screw for preventing withdrawal of the screw from an opening. Engagement of the screw with the tang also causes a reversely curved porton of the tang to engage an abutment for preventing withdrawal of the clip from a slot in which it is positioned adjacent a screw receiving hole.
