Abstract: A hollow screw and related process of making is provided, wherein the hollow screw is formed from a generally circular corrosion resistant stainless steel disk cut from flat roll stock. The hollow screw includes a head and an elongated and hollow shaft having a wall thickness between about 0.2 to about 0.7 millimeters extending therefrom and defining a shank portion and a threaded portion having a plurality of threads thereon with a rotational drive mechanism configured to facilitate tightening via the threads. The process involves annealing to soften the stamped hollow screw, followed by thread rolling, and then age hardening the hollow screw. As such, the resultant hollow screw is relatively lightweight, about 50% the mass of a solid core screw made from the same material, with a sufficient thread strength to meet most aerospace applications and contributes to important aircraft fuel economy.

Abstract: A method of treating a contact surface of a steel component of a rolling contact loaded machine element (e.g. a rolling bearing element) which has a surface layer predominantly having a martensitic and/or bainitic microstructure by cold-working the region of the element adjacent the surface layer to introduce a compressive residual stress of at least 400 MPa to a depth of at least 50 microns, machining the contact surface and heat treating the cold-worked and machined steel component below the tempering or transformation temperature of the steel. Cold working can be by shot peening, burnishing or deep rolling and machining can be by grinding, honing, polishing, lapping, super-finishing, cutting or turning. The heat treatment can be at a temperature in the range 140-230 0C for a duration in the range 5 minutes to 2 hours. The component can be coated, e.g. black oxide or PVD before or during heat treatment.

Abstract: The invention provides a coating film having excellent adhesion, even without a chemical conversion film treatment being carried out as an undercoat treatment, and a metal automotive part having the coating film. A powder is deposited by powder-coating onto the surface of a metal automotive part that has been quenched after forging, and tempering of the metal automotive part and bake-hardening of the deposited powder are carried out simultaneously, thereby forming a skin film on the surface of the metal automotive part. The surface of the metal automotive part before the powder is powder-coated thereon is a work-hardened basis material surface that has been not subjected to a chemical conversion filming treatment.
