A cord-securing mechanism includes a base portion, an aperture, and a cord-securing portion coupled to the base portion. The cord-securing portion includes at least a pair of cord-retaining surfaces that oppose one another and are spaced apart by a cord-receiving slot. When used in combination with a cord, the cord-securing mechanism may assist with setting a position of the cord and with impeding the cord from returning to a default position.

A rotating eye bolt assembly with lock mechanism. The assembly includes a threaded bolt having a multi-sided head. A lifting bail includes a pair of opposed legs, a track and a central opening through the track. A bushing having an upstanding cylindrical lip is received in the lifting bail central opening. A lock plate is slidable on the track with the lock plate having an upstanding shoulder engageable with the bolt head. The lock plate is movable between a locked position for installation and removal of the assembly and an unlocked position for use of the assembly.

An unlocking tool configured for unlocking a locking system that prevents a nut from rotating with respect to a threaded stem, comprising a ring configured to be positioned around the threaded stem in operation and at least one finger extending between a first end connected to the ring and a second, free end, this finger being configured to be received and slide in a longitudinal channel of the threaded stem in operation, each finger comprising a front face that is configured to cooperate with at least one tab of the locking system so as to prevent it becoming immobilized in one of the longitudinal channels of the threaded stem.

A fastening assembly having a component flange (10), in particular of a turbomachine, having at least one bore (11) in which a sleeve (30) is placed that extends through a bolt (20) which has a head (21) that is axially secured between a rim (12) of the bore and a component flange-mounted axial limit stop (13).

A screw includes a screw cap and a shank extending downward from the screw cap. The shank has an outer circumferential surface on which a thread is formed. The shank has a lower end forming a tip section. The screw cap is extended downward to form a conic section. The conic section is provided thereon with a reverse prevention mechanism, which is constructed to include at least one step structure. After the screw is screwed into a workpiece, in an attempt to screw the screw out of the workpiece, the reverse prevention mechanism providing a blocking and resisting effect to prevent the screw from being readily screwed out of the workpiece and thus, a reverse prevention effect of the screw can be enhanced to thereby improve overall performance of use of the screw.

A wheel retention system is provided for retaining a wheel on a vehicle. The system includes a plurality of connector receiving openings in a wheel hub flange, with each wheel hub flange including a raised bolt stop at each bolt receiving opening. A plurality of threaded connectors or bolts is provided, with each bolt received in one of the bolt receiving openings. Each bolt has a head with a flattened or clipped surface that meshes with the raised bolt stop in each bolt receiving opening on the wheel hub flange. These raised bolt stops positively prevent the bolts from rotating in the openings.

A nut plate assembly includes a plate member comprising an aperture defined therethrough. The nut plate assembly also includes a shell member having a first end joined to the plate member and a second end opposite the first end. The nut plate assembly further includes a bias member disposed within the shell member and a nut comprising a shoulder portion configured to receive a portion of the bias member. The nut is disposed within the shell member and moveable between a first position proximate the shell member first end and a second position proximate the shell member second end. The bias member is configured to bias the nut toward one of the first position and the second position. The nut plate assembly also includes a retention member configured to retain the nut within the shell member.

A support assembly (10) having a structural element (12) having first and second non-parallel adjoining surfaces (18), a bracket (14) attached to the structural element (12), and a component support (16). The bracket (14) has a first flange (20) including a first attachment surface (24) adhesively bonded to the first surface (18) of the structural element (12), a second flange (20) including a second attachment surface (24) adhesively bonded to the second surface (18) of the structural element (12), and a connection portion (48) interconnecting the first and second flanges (20), the connection portion (48) extending spaced from the structural element (12) such that a gap (52) is defined therebetween. The component support (16) is engaged to the first flange (20). The connection portion (48) may have a lower resistance to rupture than that of the first and second flanges (20). A method of removably securing a component to a structural element is also discussed.
