摘要： The present invention is directed to an internally threaded prevailing-torque type self-locking fastener which employs a patch of fused thermoplastic material as the locking element and which satisfies the functional torque requirements of both IFI 100/107 (1987) and IFI 101 (1987). In accordance with the present invention the fastener comprises a metal body having a bore extending to its opposing ends, the bore having a threaded surface; a patch of polymeric material applied and fused to a portion of the threaded surface; and the fastener meeting the prevailing-torque characteristics specified in both IFI 100/107 (1987) and IFI 101 (1987). The invention is also directed to a process wherein an internally threaded fastener is processed by first applying and fusing a polymeric resin material to at least a portion of the fastener's threaded surface and thereafter conditioning the frictional properties of the fastener such that its prevailing torque performance characteristics meet both IFI 100/107 (1987) and IFI 101 (1987).

摘要： Apparatus and method employed in applying a useful coating to fasteners is disclosed. Particularly, a resin material in powder form is preferably applied to a selected surface of the fastener to cover a desired length of the threads of the fastener. The apparatus includes a support for moving the fasteners deposited thereon to a position where the coating is applied, and a positioning device is provided to insure that the fastener is peripherally located for application of the coating. A cam mechanism associated with a plurality of tubes provides movement of the tubes for application of the resin material to the fasteners. The fasteners are subsequently removed from the support by fluid pressure.

摘要： The present invention is directed to a process for the application of fluoropolymer to a preselected area of a threaded fastener, and particularly to substantially all of the threads of the fastener. The fluoropolymer is supplied to a spray nozzle in powder form and is subjected to a triboelectrostatic charging process so that individual particles discharged from the spray nozzle are electrically charged to between about 1×10−7 to about 3×10−3 coulombs per kilogram. In the preferred form of the invention, the fluoropolymer powder is triboelectrically charged, entrained in an air stream discharged from the nozzle and directed onto the preselected area of the fastener. In this manner a generally uniform powder coating is deposited onto the preselected area of the fastener while the fastener is maintained at room temperature. Thereafter, the fastener is heated to a temperature above the melting point of the fluoropolymer to thereby coalesce the deposited powder into a continuous film coating which adheres, upon cooling, to the preselected area of the fastener. In accordance with a preferred embodiment, the fastener is heated in a manner which raises the temperature of only the preselected area of the fastener to the fluoropolymer melting point. This preferred heating technique minimizes the retention of fluoropolymer inadvertently deposited on areas of the fastener other than the preselected area, and allows this undesired fluoropolymer to be easily removed, even after heating.

摘要： An apparatus and method for applying a resin coating to a plurality of discrete portions of a fastener, such as both internal and external threads. A conveyor supports a fastener. The fastener is first transported past a heater and then past a first powdered resin spray assembly. Powdered resin, supplied to the first spray assembly by a resin reservoir, is used to generate a first air-borne powdered resin stream which coats one set of threads with resin when the fastener traverses the resin stream. The conveyor also transports a second resin spray assembly through the first air-borne powdered resin stream. The second spray assembly uses a resin receiver to aspirate the air-borne resin. The resin is then used to generate a second powdered resin stream which coats the other set of fastener threads.

摘要： An apparatus for coating internally threaded fasteners, particularly closed end fasteners, such as flanged weld nuts, which includes a powder spray arrangement, has a spray nozzle within a spray cylinder. The spray nozzle arrangement is actuated by an air cylinder to be in abutting relationship with a fastener seated in the spray position. The spray nozzle is tapped for the supply of air and for the supply of powder to the fastener threads. The spray block on which the nut is sprayed has a vacuum line that exhausts excess powder that does not adhere to the threads.
