Abstract: A nut integrated with a bracket and a method of manufacturing the same is provided. The method includes a pre-drawing operation that forms a reference aperture and a processing cross section in the plate material supplied between the punch and the die, forming a beading portion and piercing a center of the beading portion. A forging operation forms a pipe portion having a tube shape and processes an exterior circumferential surface of the pipe portion. A precision forging process adjusts dimensions of the pipe portion formed in the tube shape, forms a protruding end that extends on a tip surface of the pipe portion and compresses the pipe portion to remove residual burrs on a surface. A post-processing operation cuts the processing cross section to a final product shape, and forms a threaded tap on an interior circumferential surface of the pipe portion.

Abstract: A torque nut includes a threaded passageway and a groove. The groove has its opening facing the passageway. A breakaway insert having a major body portion is formed in the passageway, and a tab connected to the major body portion is formed in the groove, for example, by injection molding. The tab connected to the major body portion prevents rotation of the insert in the passageway. In one use, a resin component, a catalyst component and a first end of a rock-bolt are positioned in a bore hole. The torque nut is threaded onto the opposite end of the rock-bolt. Rotation of the torque nut rotates the rock-bolt, mixing the components. After the components set, increased torque is applied to the torque nut to fracture the insert and move the nut up the threaded end of the rock-bolt against roof stabilizing components.

In another embodiment, the locking unit has different sized edge cut-outs prohibiting the locking insert from rotating within the nut. The locking unit may also include a longitudinal split and a key and a keyway. A manufacturing process is also disclosed.

Abstract: A nut plate is formed from a generally U-shaped clip having first and second elongated legs and a connecting leg extending therebetween. The first leg has an opening therein for receipt of a nut and for securing the nut in the leg. The second leg has a pass-through opening opposing the nut opening. The nut is fully passed through the pass-through opening for securing in the first leg. The nut can be positioned in the first leg without deflection and urging away of the legs from one another. A method for making the nut plate includes the steps of forming an elongated strip, forming a nut opening in the strip and forming a pass-through opening in the strip. The strip is bent to define a clip having the first and second legs and the connecting leg. The clip can be heat treated. A nut is then passed through the pass-through opening into the nut opening and is secured to the first leg.

Abstract: A metallic fastening member of a one piece configuration formed of a metal material includes a shaft and a flange extending outwards from a first end of the shaft. The shaft includes a relatively thin-walled portion to be caulked at a second end opposite to the first end. A female threading is formed at an inner peripheral face of the shaft excluding the portion to be caulked. An annular groove is formed at an outer peripheral face of the shaft or at the inner peripheral face of the portion to be caulked, so that the shaft has a partially thin wall. Since the wall of the shaft is thinner at the annular groove, the metallic fastening member can be fractured at that area so as to be separated into upper and lower pieces when detaching the metallic fastening member from a workpiece. Therefore, the metallic fastening member can be readily removed from the workpiece to facilitate the recovery work for recycling purposes.

Abstract: A composite fastener which is comprised of a nut having a neck at one of its axial ends, and of a washer which at least partially surrounds the neck and is adjacent an external shoulder of a non-circular main section of the nut. That end of the neck which is remote from the shoulder is expanded to prevent an unintentional separation of the washer from the nut. The making of an internal thread in the nut is carried out subsequent to the expansion of the neck. The nut and the washer can constitute converted blanks which are converted by resorting to a press forging or cold forming or turning procedure.

Abstract: The fastener comprises, in combination, a screw having a threaded shaft, and a fastening strip or sheet having a raised portion provided with an aperture being preformed to have an at least partly helical threadform-defining edge shaped and dimensioned to matingly receive the threaded shaft of the screw means. The crests comprising the threaded shaft of the screw means have an asymmetrical surface profile in the axial direction of the threaded shaft which enables the shaft to withstand greater applied torque.
