ABSTRACT:
By providing a locking member having collapsible and bendable arm members which cooperate with a head-bearing fastening member, a unique fastening system is achieved which enables hardware products, such as handles, knobs, locks, brackets, and the like to be easily and quickly mounted to any desired furniture product. In the preferred embodiment, the head-bearing fastener and the locking member are constructed to be axially inserted through the mounting holes formed in the furniture product. Then, by mounting the fastening system to the hardware product and inserting the mounted fastening system through the mounting holes, the hardware product is quickly and easily securely affixed in position as the collapsible and foldable arm members of the locking member are forced outwardly into an overall width greater than the mounting holes during the threaded advance of the fastener with the hardware product.
