Abstract: A fastener for fastening parts together. The fastener has a shaft, a head and movable members that spring outwardly from the shaft to firmly capture the parts between the members and the head upon insertion of the fastener into aligned holes in the parts. No threading step is necessary. The movable members may be retractable into the shaft to facilitate insertion into holes corresponding in size to the shaft. The members may have a contact surface sloping away from the head and forming a tapered space between the members and the head so that the outward spring bias tends to reduce the space and maintain tightness of the joint. The fastener may be operatively deployed by a single insertion step.
