Abstract: An apparatus for and a method of securing hubs and bearings on truck spindles includes a flat or non-flat washer with a key and a nut having an integral and axially spaced locking ring with threads through the nut and locking ring complementary to threads on a spindle. The nut also includes a plurality of axially oriented threaded openings and a plurality of threaded fasteners that extend through apertures in the locking ring and into the threaded openings. An alternate embodiment includes a washer, a nut having threads complementary to threads on the spindle and a plurality of axially oriented threaded openings, a locking plate having a pattern of arcuate slots and a key which engages a keyway on the spindle and a plurality of fasteners which secure the locking plate to the nut in a desired position.

Abstract: A threaded ring has a single-component body provided with an internal screw thread (14, 16) and two body parts (10, 12). The first part (10) forms an adjusting ring having an end face (22) located on a radial plane. The second body part (12) forms a security ring connected to the first body part (10) by an elastically flexible wall part (32) of the body, forming a gap (26) between the two body parts. An actuating device can adjust the geometry of the gap (26) due to the elastic flexibility of the wall element (29) along the longitudinal axis of the body. A bearing surface (46) having a predefinable inclination is arranged in the premounting state between parts of the actuating device and parts of the body.

Abstract: A threaded ring has a single-piece body provided with an internal screw thread and two parts (1 and 3). The first part forms an adjusting ring having an end face (11) located in a radial plane. The second part (3) forms a retaining ring connected to the first part (1) of the body by an elastically flexible wall part (29) of the body forming a gap (15) between the two parts of the body (1 and 3). An actuating device (31) permits the geometry of the gap (15) to be adjusted due to the elastic flexibility of the wall element (29). The second part (3) of the body, used as a retaining ring, has a peripheral region (21) for the formation of the elastically flexible wall element (29), and has a smaller outer diameter than the first part (1). The outer diameter of the peripheral region is located on a smaller radius than the radially outer end (17) of the gap (15). The outer end of the gap, in turn, is located on a smaller radius than the periphery (19) of the first part (1) of the body.

Abstract: A self-locking threaded element that is used, for example, in a tool receptacle of a grinding tool. The self-locking threaded element comprises a retaining member (1) and a main part (3) axially disposed relative to the retaining member (1) at a distance (a) and connected with the retaining member (1) by a connection web (2). The main part (3) and the retaining member (1) are interspersed with a thread (4) for engaging a counter-thread. The retaining member (1) is displaceable relative to the main part (3), at least in the longitudinal direction (L) of the thread (4), to provide a self-locking threaded element that is inexpensive to manufacture and enables both simple tightening and loosening of the threaded element.

Abstract: A blind fastener with an improved drive nut and assembly process. The blind fastener includes a screw, a sleeve, a nut, and a drive nut. The drive nut has a smooth bore and protruding nibs that mate precisely with a driving recess located in the nut head. An end of the drive nut opposite the nibs is deformed to retain the drive nut on the screw against the nut. Once the new assembly process for the blind fastener has been completed, the drive nut will have been mated with the nut head to prevent any rotation of the nut during installation of the blind fastener. The assembly process will now include placing the sleeve over the threads of the screw to a position adjacent the screw head. The nut is then threaded onto the screw adjacent the sleeve. The drive nut's protruding nibs are next aligned and physically engaged into the driving recess of the nut head by sliding the smooth bore over the screw.

Abstract: A reamer screw having an elongated shank, with a leading end and a trailing end, at opposite ends, and having a self-tapping/cutting threaded portion at the leading end adapted for self-tapping and cutting an opening through a workpiece, and driving securely into a substrate, a torque formation at the trailing end for engagement by a suitable driving tool for the single function insertion of the threaded portion through the workpiece and into the substrate, in a single operation, a smooth shank portion extending between the threaded portion and the trailing end and having a length sufficient to extend through the workpiece, driving in of the threaded portion through the workpiece, releasing the workpiece allowing the threaded portion to be tightened up in the substrate, while the smooth shank portion rotates freely in the workpiece permitting the workpiece to be drawn snugly against the substrate without binding in the workpiece, and reamer formations formed by outwardly extending wing portions of the smooth
