Abstract: In accordance with one or more embodiments of the invention, nut restrainers, centering tools, and methods of use are presented, particularly as applied to high strength bolted connections. Nut restrainers may have an interior profile including a circular profile section and a regular hexagonal profile section, a nut inserted into the nut restrainer may have lateral freedom of movement, and the nut restrainer may have a top plane with one or more centering protrusions. A centering tool for positioning a nut restrainer may have a non-circular head section, a cylindrical positioning section, a threaded section, and a cylindrical restrainer positioning section; a method of positioning a nut restrainer coaxial with a bolt hole using the centering tool.

Abstract: A mounting assembly for a gauge wheel on a row unit allows for infinite lateral adjustment of the gauge relative to an opening disc on the row unit. The mounting assembly includes an arm with a threaded bore extending through a split end of the arm. A threaded bushing is adjustably mounted in the bore and secured in a desired position with a bolt standing through the split end to clamp bushing in position. The split end mounting arm provides a method of quickly and easily adjusting the lateral position of the gauge wheel on the row unit in infinite increments.

Abstract: The invention provides a type of elastic nut, primary comprising first and second compression slots allowing for compression and connecting strips at the bottom of the retaining nut, with the connecting strips in alternate positions, so that when the retaining nut is used to hold a plug in place on the bolt, and further torque is applied to the retaining nut, the nut is held in place on top of the plug with elastic force, effectively holding the plug in place more tightly.

Abstract: A bearing arrangement for a roll of a rolling mill stand includes a bearing for supporting a roll neck, a hydraulic device for securing the bearing on the roll neck and having a hydraulic piston supported against the roll neck, and a hydraulic cylinder displaceable relative to the hydraulic piston, the hydraulic piston having an outer thread on which a circular nut having a circular base body is screwable for supporting the hydraulic cylinder with respect to the hydraulic piston, with the nut having a circular projection extending coaxially with the circular base body and completely attached to the circular base body.

Abstract: The invention relates to a threaded fastener. In particular, the invention relates to a threaded fastener such as a nut or a bolt. In an embodiment of the invention, a threaded fastener in the form of a nut (10) is disclosed. The nut comprises a main body portion (12); a lip portion (14) extending from the main body portion; and a recess (16) formed in the main body portion adjacent the lip portion. The recess is shaped to receive at least part of the deformable lip portion when a mating torque is applied to the fastener causing the deformable lip portion to deform. In this fashion, when the fastener is used to clamp two or more components together, such as flanges (20, 22) on adjacent pipe sections, the lip portion encounters a surface of the component that the fastener is being used to clamp against. As the fastener is torqued-up to a desired level, to provide a determined mating force, the lip portion is deformed into the recess in the main body portion.

Abstract: The conduit body assembly includes a metallic conduit body having an open upper end and a metallic cover removably positionable over the upper end. A metallic threaded fastener secures the cover to the body. The metallic fastener includes a threaded post and a nut removably attached to one end of the post. The nut and the post are formed of similar non-corrosive materials so as to resist corrosion therebetween. The nut is removable from the post in an environment where corrosion between the metallic fastener and the conduit body and cover prevents removal of the threaded fastener therefrom. Removal of the nut from the threaded post permits removal of the cover from the conduit body.

Abstract: A lock nut having a plurality of sides having a radius crimp which is consistent with the radius of the threaded bore in the lock nut. Preferably, the lock nut is crimped using a three sided die, each die having a radius crimp with relief angles. The relief angles are provided at a desired angle to result in the desired amount of contact area between the lock nut and the die. The device includes a housing, and the housing includes at one end a threaded bore which is configured to mount on a ram. An opposite end of the housing provides a tapered die section in which the three sided die is disposed. The three sided die is engaged with a locking die base which is movable within the housing.

Abstract: A construction hanger used in connection with a beam, the construction hanger including a bracket defining an opening for receiving a portion of the beam, a first receiver having an internal thread, and a second receiver through which a support member or fastener is slidably received, where the support member or fastener has a threaded end that may be received in the first receiver. The construction hanger further includes a retainer that engages the threaded end after it is inserted through the second receiver to prevent bracket from sliding downward on the support member or threaded fastener allowing the installer to position the bracket on the support beam before fastening the threaded end in the first receiver.

Abstract: A locking assembly for fastening two components together, such as a fluid coupling assembly, is disclosed. A first member has a serrated annular surface and fastening threads adjacent a bearing surface. A second member has a flexible projection or projections or a complementary configuration to the serrated annular surface. The second member also includes fastening threads and a bearing surface. When the respective threads engage, they provide the primary preloading force to the bearing surface, while simultaneously the projections and the serrated detects provide a retention force to ensure a positive coupling.

Abstract: A temperature-sensitive, deformable cylinder locknut for use in high temperature applications associated with the operation of a gas turbine engine provides a secure fastener lock which resists torsional and vibrational stresses which may otherwise act to unseat and disengage the bolt. The locknut includes an undeformed threaded portion, an unthreaded transitional cylindrical sleeve portion, and a deformable unthreaded cylindrical portion. A threaded shaft contacts the cylindrical sleeve with reduced surface engagement to minimize frictional interaction and define a spiral volume therebetween to ensure the establishment of a non-permanent lock.

Abstract: A laminated nut comprising a plurality of conical spring discs or spring washers and a cage for receiving and holding the spring discs in a stacked, aligned relationship to define a central opening threaded to the matably received upon an associated threaded bolt, with the cage comprising a plurality of fingers nested within slots defined in the flats of the spring discs and including protrusion means at one axial end of the nut cage to preclude gripping of the nut by a wrenching tool at the one axial end and including a method of manufacturing the laminated nut.

Abstract: A nut and stud assembly for securing workpieces via threaded engagement of the stud with one of the workpieces and engagement of the nut with another of the workpieces and with the nut preassembled on the stud with the stud having a stop preventing the nut from advancing further on the stud until the stud has reached a preselected position in the one workpiece whereby the nut and stud assembly will function similarly to a headed bolt until the preselected position is attained and thereafter the stop will permit movement of the nut on the stud through such stop and be free running to function similarly to a separate nut and stud combination to a final clamp up of the workpieces.

Abstract: A self-locking nut is provided having, at its periphery, a number of longitudinal channels (3) with semi-circular section intended to cooperate with drive balls carried by an appropriate tightening tool, said balls causing, at the end of tightening, the formation of a circular groove (10) by forcing back the metal situated between the channels (3), which results in radial deformation of the inner threads of the nut (1) at the level of said groove (10).
