摘要： 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.

摘要： A drain plug includes a main body which has an entirely threaded region and a partially threaded region. An outer circumferential surface of the main body has an external thread, and at least one cutout. Thus, the entirely threaded region is formed on a base end side of the main body. The cutout includes a first part extending from the leading end of the main body in the axial direction of the main body, and a second part extending from the first part in a direction toward the base end of the main body. The second part has an inclined surface, and the inclined surface is connected to the entirely threaded region.

摘要： The present invention is an assembly and method for continuously manufacturing fasteners. A die press actuated at a first speed receives the contoured wire into a die having a piercing element for piercing an aperture and a cutting element for cutting a fastener from the wire. A guide receives the fasteners from the die press and a drive unit engages the fasteners oriented by the guide and conveys the fastener to an elevated height relative to a tapping device. The guide redirects the fasteners by a first router. The fasteners are gravity fed into the first router and redirected to one of the tapping devices. Each tapping device has a tapping element for forming internal ribs in the aperture of the fastener. The tapping devices each actuates at a second speed that in aggregate is generally equal to the first speed of the die press.

摘要： A self-piercing hollow press-in element, in particular a nut element for attachment to a sheet metal part, wherein the press-in element has a flange part of a larger diameter and a shaft part of a smaller diameter. The shaft part extends away from the flange part and has a circular piercing edge at its end face remote from the flange part. The side of the flange part facing the shaft part forms a sheet metal contact surface in ring shape and features providing security against rotation are provided at the shaft part which extend approximately from the level of the sheet metal contact surface over a part of the length of the shaft part along the latter. A ring-like recess is provided radially within the ring-shaped sheet metal contact surface in the flange part and excess material for the shaft part which arises during manufacture of the ribs providing security against rotation is located within the ring recess. Further designs of the press-in element and also of a component assembly and methods for the manufacture of the press-in element and of the component assembly are described.

摘要： A method of forming pierce and clinch nuts by rolling a section having the desired cross-section, punching equally spaced bores through the central pilot portion and then punching configured openings through the central pilot portion having convex arcuate surfaces and eliminating sharp corners. The strip of interconnected self-attaching fasteners may be installed directly from the strip in a panel, fed in bulk or separate fasteners interconnected by frangible connectors. The resultant self-attaching nut includes a central pilot portion having a bore through the top face, integral flange portions extending from opposed sides and the pilot portion includes convex arcuate faces reducing or eliminating stress cracking and propagation of stress cracks.

摘要： It is an object of the invention to provide a tap holder in which even when an error is brought about in synchronizing spindle feeding and rotation of a tapper body and a tap collet of a tap holder in correspondence with a machine tool spindle, the synchronization can be established by absorbing the error by a simple constitution. As means therefor, the tap holder is characterized in that a tapper body and a tap collet are inserted by a locking member at portions of the tapper body and the tap collet overlapping each other, and the tap collet is fixed to the tapper body by engaging the locking member with at least one of the tap collet and the tapper body in a state of being interposed with an elastic member on both sides thereof in an axial direction X.
