Abstract: A fastener for use for attaching metal parts has a socket member and a stud member slidably and fixedly received therein. A flair portion on the socket member expands when abutted by a camming portion on the stud member to move the fastener between unlocked and locked positions. The head of the stud member includes a beveled edge which complementarily fits against a bevel abutment within the socket head. The bevel abutment extracts the stud member from the locked position by turning the stud member in either axial direction to ramp the stud member out of the socket member.

Abstract: A shelving assembly has an integral product display and provides an adjustable track for the product display to roll along. The track may be adjusted both horizontally and vertically to allow the user to tailor the track to fit different shelving sizes and configurations. A carriage within the track rolls on wheels which are oriented in both the vertical and horizontal plane. A slider framework extends downwardly from the carriage and provides a display box for the customer to view an unboxed and preferably assembled sample of a product for sale. The slider framework is removably secured to the carriage, or in the alternative, the display box is removably secured to the slider framework, so the user may easily remove and replace display samples.
