摘要:
A female threaded body (100) is provided with: a female threaded helical structure (114) formed on the inner circumferential surface of a hole (106a) in a cylindrical member (106); a contact surface (110a) formed on an axial direction end face of said cylindrical member (106); and a reverse rotation-preventing member (160), which has a protruding section (168) that is disposed and fixed on said contact surface (110a) and protrudes radially inward toward the rotation axis and in which the tip of said protruding section (168) configures an engaging edge (168a) that forms a continuous or discontinuous helix of a different lead angle and/or lead direction from the lead angle and/or lead direction of the female threaded helical structure (114). The engaging edge (168a) may allow a relative rotation of a male thread body (10) and the female threaded helical structure (114) in one direction.

A self-locking plug is provided that includes a lock carried between a sleeve and a core. The sleeve has an anti-rotation feature for reducing axial rotation of the sleeve during at least one of core removal and core installation. The core extends through the sleeve. The lock includes a first component and a second component. The first component has a protrusion that extends radially out to a circumferentially extending interference surface. The second component has an interference tab that is radially biased against the interference surface.
摘要:
A fastener for use where a predetermined holding force of holding position is to be maintained while the fastener is required to exert a holding force less than the full maximum force it is capable of exerting, the fastener having a shaft portion that threadedly fits into a nut, the shaft portion having an angular cut forming a spring like member, with an outer projecting portion biased toward a surface of the nut for causing a resistance to rotation of the fastener relative to the nut, and wherein the nut may take the form of a thrust collar that receives a number of the fasteners for maintaining a bearing on a journal.
摘要:
A fastener clip for detachably securing functional elements to a support plate through threaded pins rigidly joined to the plate which includes holding members forming channels which receive the functional components and a fastening hole between the channels and adapted to receive the threaded fastener. The fastening hole has an inside diameter slightly less than the outside diameter of the pin and is interrupted by a plurality of apertures extending through opposite side walls of the clip between the channels. Semi-circular wall portions at the end of each aperture define the fastening hole and elastically yield when the clip is forced on the threaded pin.
摘要:
A quick release fastener comprising a stud sub-assembly having a bearing washer and retaining washer to hold the stud captive in a panel and a nut sub-assembly comprising a split resilient nut sleeve captive in a yoke which is secured to a sheet to which the panel is to be attached.
摘要:
This disclosure describes a lock nut member including a body portion having an opening extending therethrough and a plurality of resilient locking segments joined to the body portion and extending generally axially thereof to define an extension of the opening. The interior surfaces of the locking segments are threaded to receive an externally threaded member. When the externally threaded member is received within the locking segments, the locking segments firmly grip the externally threaded member and are deflected radially outwardly. The locking segments are constructed so that they will deflect in a manner approaching the deflection of a flat beam.
