Abstract: A nut to be used as part of a fastener to be used in multiple ways in various industries or methods has a drive mechanism and stud extending from the drive mechanism with a threaded bore. In addition the nut can be specifically used as a method and as part of special fastener that can be used to join cut, hard-wood members, other naturally occurring manufactured mat members or synthetically man made members, referred to as “timber(s)” or “laminated”, in forming a mat used for heavy construction equipment to run on over ground which is not stable. These mats are commonly referred to as “Crane Mats” or “Laminated Mats” in the construction, mining, pipeline, and oil and gas industries among others.

Abstract: A jackscrew nut and/or bolt head assembly includes a bottom washer that is interlocked via circumferentially arrayed castle extensions and recesses. Spherical faces at the washer top are thereby held in alignment with corresponding spherical jackscrew bottoms, which assures evenly distributed contact pressures during out of angle elastic jackscrew displacement during jackscrew loading. The bottom washer interlock may provide further for a transfer of a primary pre tightening torque exerted onto the main body of the nut and/or bolt head via a tool that concurrently accesses all jackscrew heads extending above the main body. The assembly may be initially tightened via the primary torque whereby secondary jackscrew actuation and displacement is greatly reduced. The jackscrews are thinned in reverse for maximum contact area at their spherical bottoms.

Abstract: A jackscrew nut and/or bolt head assembly includes a circumferentially and radially interlocked bottom washer. Spherical faces at the washer top are thereby held in alignment with corresponding spherical jackscrew bottoms, which assures evenly distributed contact pressures during out of angle elastic jackscrew displacement during jackscrew loading. The bottom washer interlock may provide further for a transfer of a primary torque exerted onto the main body of the nut and/or bolt head via an outside spline such as well known triple square, twelve spline or the like, which may be incorporated also into the bottom washer for a concurrent application of an external torque. The assembly may be initially tightened via the primary torque whereby secondary jackscrew actuation and displacement is greatly reduced.

Abstract: A locknut system having a projecting screw threaded member with a first external thread. A nut is mountable on the projecting screw threaded member by means of a corresponding thread. A second different screw thread is formed on the projecting screw threaded member. The second screw thread is of a different hand or a different pitch from the first screw thread. A locking member has a screw thread for engagement with the second screw thread of the projecting screw threaded member and has an engaging surface which can be brought into abutting contact with a corresponding engaging surface on the nut by mating the thread of the locking member with the second thread of the projecting screw threaded member. A coupling member operates to couple the locking member and the nut to substantially prevent relative rotation there between.

Abstract: It is intended for joining two pieces (1 and 2) that are in contact with each other via their respective inner faces (3 and 4), with one of them having a blind threaded hole (5) in which is coupled a first threaded end segment (6) of a bolt (7) which includes an annular extension (9) that limits the tightening rotation of the bolt (7) with the interposition of a characteristic elastic washer (8) as means for immobilizing the bolt (7) preventing it from coming loose. The other piece of the pair includes through holes (13) in correspondence with each of which is housed a section (11) of the respective bolt (7), projecting out of which said piece is a second threaded end segment (14) of the bolt (7), in which segment is coupled a self-locking nut (15) which fixes the two pieces together.

Abstract: A self-locking panel nut fastener having a nut for being received within an opening in a panel which self-locks and upon receiving a threaded screw or bolt enhances the locking relationship with the panel.

Abstract: A wheel nut assembly for fixing a wheel to a vehicle hub. The wheel nut assembly has a wheel nut. The wheel nut has an internal thread. The wheel nut assembly further includes a wheel stud having an external thread adapted to co-operate with the internal thread of the wheel nut. The wheel stud further has an internal thread. A retaining member has an external thread of an opposite hand with respect to the internal thread of the wheel stud for cooperating with the internal thread of the wheel stud. A locking member is adapted to engage both the retaining member and the wheel nut to prevent relative movement there between and is further adapted to permit a location of the retaining member to be visually identified when the locking member is engaged to both the retaining member and the wheel nut.

Abstract: A highly adjustable free spinning positively locking fastener assembly for threaded joints such as automotive or truck wheel assemblies includes a nut having a flange with a retainer washer captured on the nut flange via a locking bolt. The washer includes a tab received in a slot of a wheel spindle to permit the washer to move axially and prevent the washer from rotating. Bolt holes are located at unequally spaced opposed locations in the flange of the nut. A plurality of locking bolts locking the nut to the washer to prevent relative rotation so that neither the nut nor the washer can rotate relative to the spindle. The locking bolts are torsionally inserted into the locking bolt holes located in the nut. At least one locking bolt extends through at least one of the corresponding locking teeth of the washer. When the locking bolts are inserted into the locking bolt holes, the locking bolts engage the teeth of the washer to prevent the nut from rotating.

Abstract: A rack and pinion steering gear (10) comprises a rack (14) and a housing (12) for receiving the rack. The housing (12) has a chamber (42) for receiving a rack supporting yoke (70). The chamber (42) has a threaded portion (44) with internal threads (45). A rack supporting yoke (70) is disposed in the chamber (42) and supports the rack (14) for movement in the housing (12). An externally threaded yoke plug (90) is screwed into the internal threads (45) of the threaded portion (44). An externally threaded lock nut (120) is screwed into the internal threads (45) of the threaded portion (44) and into abutting engagement with the yoke plug (90) to lock the yoke plug in the housing (12).

Abstract: In a modular system (10), with a holder part (12) for clamping in a spindle of a turning machine and a machining tool (14) attached interchangeably to this, the machining tool (14) has a hollow cylindrical shaft part (18) which overlaps a receiving mandrel (20) on the holder part (12) and is fixed to the holder part (12) by means of a screw device (28, 30) mounted on the holder part (12) and generating a tension or compression force via a tension or compression rod (22) running through the holder part (12) and the receiving mandrel (20). The end of the tension or compression rod (22) facing the machining tool (14) is expanded and under the effect of the tension or compression force leads to an expansion of the receiving mandrel (20) such that the peripheral surface (42) of the receiving mandrel (20) and the inner surface (44) of the shaft part (18) are clamped against each other to form a friction connection.

Abstract: A reusable positive locking device having a nut threaded onto a bolt shank to a certain closure position wherein a locking element is screwed onto the bolt shank against the nut and a crown element cupped over the end of the bolt shank is screwed onto the bolt shank to engage the locking element and is then given an additional increment of turning so as to elastically deform biasing means between the crown element and its threaded engagement with the bolt shank, thus closing up play among the bolt shank and the locking element and the crown and the nut, the threaded connections between the locking element and the bolt shank and between the the crown element and the bolt shank being of a different direction, and the locking and crown elements being held together against relative rotation by releasable detent means.

Abstract: Apparatus for an adjustable low-loss capacitor, which can withstand the application of high shock forces without a corresponding change in a preselected value of capacitance, is described. This capacitor has two sets of hollow cylindrical electrodes which are coaxially interleaved, with, more particularly, one set attached to a rotor unit and the other to a stator unit, all contained within a housing. The capacitance is varied by longitudinal, i.e., axial, movement of the rotor unit with respect to the stator unit. The rotor unit is threadedly inserted into a bushing. In addition, the rotor unit includes a frictional locking mechanism which comprises a threaded member which is inserted into a hole cut into the rotor unit and oriented substantially parallel to the center axis of the rotor. As this threaded member is turned, one portion of the rotor unit moves, with respect to another portion, in a longitudinal direction substantially parallel to a center axis of the rotor unit.

Abstract: The mechanism allows the bin to be manually moved from a stowed position to a loading position, and requires support arms which are mounted with self-aligning bearings for proper operation. The bearing has three parts: an interior bin mounted needle bearing axle unit; an exterior bin mounted nut; and an axle retainer unit in the arm. Installation and repair are accomplished from the interior of the bin by the turning of the bearing axle bolt which is threaded unto the arm, and upon disconnection from the arm is automatically gripped by a retainer washer for retention inside of the needle housing while the bin is in its loading position and momentarily arrested by a pin connecting both arms. Self-aligning and linear control is accomplished by the substantially wide needle bearing housing providing full support to the solidly mounted axle bolt.

Abstract: A theft deterrent device for "bolting" pieces of material together, comprising:(1) a nut-like device having a smooth outer surface resistant to the effects of conventional wrenches,(2) a male threaded member having an internally threaded axial bore, adapted to threadedly engage the nut-like member,(3) a locking screw for threadedly engaging the internal bore of the male member, and having a head that mates with the smooth outer surface of the nut-like device, resulting in an essentially smooth, continuous outer surface resistant to removal using conventional wrenches, and(4) an environmental plug for inserting into the driving recess or bore of the screw to prevent foreign and corrosive matter from entering the recess. The locking screw threads are of opposite hand to that of the nut-like portion, so that the locking screw must first be removed before the nut may be removed.
