ABSTRACT:
A high strength positive locking fastener for securing structural panels together is disclosed. The fastener includes a stud receptacle and a stud assembly. The stud receptacle is mounted on an inner panel spatially fixed with respect to an outer panel and includes an interiorly threaded basket nut with assembled washer fixedly mounted thereon and a cage which is fastened to the inner panel and which movably receives the basket nut and washer assembly. The stud assembly passes through substantially coaxial openings in the panels and then into the basket nut assembly. The stud assembly includes a threaded stud having a bore therethrough containing a spring loaded plunger with a pair of locking balls resting thereon. To engage the fastener and secure the panels together a tool is used to depress the plunger forcing the balls against a reduced plunger diameter and allowing the stud to pass through the panel openings and into the basket nut. The stud is then threaded into the basket nut and, when the tool is removed, the plunger returns to its fully exended position with the balls resting on a larger plunger diameter thereby preventing the stud assembly from passing through the panel openings. To remove the fastener and separate the panels, the tool is used to depress the plunger allowing the balls to rest against a reduced plunger diameter and the stud is unscrewed from the basket nut.
