Abstract: In a socket assembly having a housing with a closed end and an open end and an axially slidable and rotatable bearing, a spring washer seated on the axially slidable and rotatable bearing with a protrusion or a recess on the external periphery for engagement with a cooperating recess or protrusion on an inner cavity of the housing to effectively stop movement of spring washer with the axially slidable and rotatable bearing during driving conditions.

Abstract: Threaded mechanical fastening systems and methods are provided that allow the simple deflection of a washer to indicate that a desired minimum torque has been reached or that a desired maximum torque has been exceeded. The method includes providing a threaded connection having a washer, installing the threaded connection so that the washer is supported as a simple beam over a gap, and using an amount of deflection of the washer as a result of torque applied by the threaded connection as an indicator. The torque indicating threaded mechanical fastening system includes a threaded connection and a washer supported as a simple beam over a gap so that the threaded connection, when tightened to a predetermined torque, deflects, in bending, the washer into the gap.

Abstract: The present invention relates to a screw providing a balance weight to be secured to a household appliance, for example a washing machine, in prestressed manner, having a head providing the screwing operation to be performed by being rotated, mounted with a spring washer on the lower side, and a shank extending under the head having a threaded portion thereon, a cylindrical shoulder disposed on the part of the screw where the shank joins with the head, with a diameter greater than that of the shank.

Abstract: A male F-Type coaxial cable connector with a body prod, the body prod for urging a connector nut into contact with a connector post.

Abstract: The present invention relates to a self-locking bolt-nut assembly including a bolt; a nut tightened on the bolt; and a washer provided between the bolt and the nut, wherein the nut has a counterbore being formed in the nut, and has a plurality of stop protrusions formed on the inner surface of the circumferential sidewall of the counterbored portion of the nut, the stop protrusions being arranged in a circumferential direction at regular intervals, the washer including the rotation-preventive protrusion protruded on inner circumference of the washer towards the center thereof, the rotation-preventive protrusion being inserted into the insertion guide groove; and a plurality of elastic protrusions which is protruded on outer circumference of the washer, being inclined in the direction where the nut is turned to tighten it.

Abstract: A ceiling hook (H) comprises a fastener (F) for anchoring in a support structure, and a locking ring in the form of an anti-rotation washer (W). The washer (W) includes anchoring teeth (34) for stationarily mounting the washer (W) to the ceiling. The hook member (12) and the washer (W) comprise co-operating locking ratchet elements (22, 28) for locking the fastener (F) to the washer (W) and thus preventing the fastener (F) from loosening from the ceiling. The washer (W) defines at a central opening (30) thereof at least one notch (32) with the fastener (F) defining at least one tab with (26), the notch (32) being slidable through the tab (26) for mounting the washer (W) to the fastener (F) and then allowing it to rotate between the tab (26) and the book member (12), whereby the washer (W) is prevented from being removed from the fastener (F) unless the tab (26) and notch (32) are aligned.

Abstract: A shaft seal having spacers positioned between the packing follower and the body of a valve. The spacers are flat, hard members of a certain thickness which allow maximum tightening of the packing fasteners and determine the maximum pressure the packing follower exerts on the packing material. The spacers have a slot for accommodating the fasteners and a tab that can easily be grasped with a tool, such as pliers. A stack of spacers can be positioned between the packing follower and valve body and then sequentially removed to provide incremental tightening of the fasteners for maintaining pressure on the packing materials by the packing gland. The spacers may include integral locking tabs.

Abstract: A snap-on ground retainer for a fastener of the type having a shank, the shank having a head at one end and a threaded portion along its length. The ground retainer comprises a relatively thin sheet metal and includes a washer-like member having an external annular body portion and an inner tooth portion, the inner tooth portion comprises a plurality of circumferentially spaced teeth extending radially inwardly from an inner margin of the washer-like member. The plurality of circumferentially spaced teeth comprise a plurality of resilient retaining teeth and a plurality of rigid grounding teeth, an inner diameter defined by the rigid grounding teeth is slightly larger than a maximum diameter of the threaded portion on the fastener and an inner diameter defined by the resilient retaining teeth is slightly smaller than a maximum diameter of the threaded portion on the fastener with which the ground retainer is adapted to be telescopically associated.

Abstract: An elongated strip of adhesively attached preassembled lock washer and nut assemblies for attachment to threaded shanks of bolts for joining members together. The strip has a strip face provided with a peelable type adhesive. A series of lock nuts each having a star washer in unitary assembly therewith. An adhesive ring with opposite faces of the adhesive ring each provided with a peelable type adhesive material with one face being retainingly secured by the adhesive to the lock nut and with the other and opposite face being secured by the peelable type adhesive to the adhesive on the strip. The lock nuts are adhesively secured in spaced relation to the strip along the length thereof in readiness for each lock nut to be peeled free of the strip for attachment to a member by the adhesive material for assembly therewith.

Abstract: A fastener having a body defining an axis of rotation extending downwardly from the body and formed integrally therewith is provided with a flange extending radially and downwardly from the body. The flange is slotted to define a plurality of deformable tabs joined at their respective bases to the body. At least a portion of each tab is twisted relative to its base about an axis extending along the flange radially from the axis of rotation in a direction so that the leading edge of each tab as defined by the slots, the edge being on the side of the tab facing in the direction of rotation of the fastener for tightening, projects downwardly.

Abstract: A sewing machine is secured to the platform of a sewing cabinet with a machine connected stud and a wing nut which is threaded on the stud and is permitted to turn only a limited amount so as to prevent excessive force from being applied to the machine.

Abstract: A screw having a head and a body defining an axis of rotation extending downwardly from the head and formed integrally therewith is provided with a flange extending radially and downwardly from the head about the upper end of the body. The flange is slotted to define a plurality of deformable tabs joined at their respective bases to the head. At least a portion of each tab is twisted relative to its base about an axis extending along the flange radially from the axis of rotation in a direction so that an edge of each tab defined by the slots, the edge being on the side of the tab facing in the direction of rotation of the screw for removal, projects downwardly. The respective ends of the edge lie in essentially a single plane extending normally to the axis or rotation, the bottom surface of the tabs defining an essentially straight line in radial cross-section except in the region of twist.
