Abstract: A system for securing a threaded fastener prepositioned in a hole in a ski binding assembly that is subsequently to be connected to a ski. The system comprises an elastic fastener retainer held within the hole that causes the lower portion of the fastener to retractably extend from the hole until a force is applied to the lower end thereof. When such a force is applied, the elastic fastener retainer is temporarily deformed, accommodating retraction of the lower portion within the hole. When the force is removed, the fastener retainer reassumes its former shape, causing the lower portion to again emerge from the hole. The system allows the assembly to be initially placed anywhere on a ski surface, and thereafter, to be moved to the location of the ski's screw holes where the assembly is to be installed.
