The channel mount may also include an engagement member engaged with the recess, and a fastener engageable with the engagement member and the at least one aperture, where engagement of the engagement member and recess prevents rotation of the engagement member during engagement of the fastener with the engagement member, whereby the first and second flanges are engageable with a towed vehicle.

Abstract: A system for preventing rotation of fasteners is provided that includes secondary locking devices. The system may include multiple fasteners that extend parallel to each other and may be arranged in a generally circular pattern. Multiple secondary locks may be arranged concentrically outside of the fasteners and have radially extending teeth so that teeth of adjacent secondary locks engage each other for preventing rotation of the fasteners. The secondary fasteners may have central openings that are larger than the fasteners to allow for substantial back-and-forth rotational movement, which may be between about 5 to 20 degrees of travel, of the secondary locks upon the fasteners before being stopped by the engagements of the secondary locks and fasteners. Inner and outer peripheral surfaces of the secondary locks may have different axes of symmetry which may allow the secondary lock teeth to be arranged asymmetrically relative to the fasteners.

Each locking tube includes a spring which urges locking pins extending upwards from a floating locking plate through perforations through a fixed locking plate into bores in the lower face of a novel locking collar-nut threaded onto a stud to fasten it to the lid, thus locking the nut from being unthreaded from the stud.

Abstract: A wheel lug nut locking device having first and second planar sections, each with an opening adapted to be fitted around a wheel lug nut. The planar sections are connected by a flexible section that allows the planar sections to be moved relative to one another. In a preferred embodiment, the flexible section has a concertina-like structure.

The plate is pivotal about both fasteners so that the plate can swivel providing flexibility in installation and use.

Abstract: A multifunction wheel nut cap is used on motor vehicle to indicate loosening and rotation of a lug nut. On large trucks on which the lug nuts have to be frequently torqued to prevent the lug nut from loosening and turning until it drops from the wheel bolt, the indication of rotation and limiting of the rotation prevents the lug nut loss and requires tightening only when there is an indication that the lug has become loose. The Wheel cap nut device gives a visual warning when a nut has become loose. It also prevents water and contaminants from penetrating the lug nut and bolt threads.

Abstract: A metal wire is configured to provide a diagonal interconnecting part extending tangentially between first and second coils which are sized to fit around respective screw action connectors. First and second wire end portions extend tangentially from the respective first and second coils across and beyond the diagonal interconnecting part to provide first and second finger grip limbs. The first limb extends across the interconnecting part adjacent the first coil and the second limb extends across the interconnecting part adjacent the second coil so that end regions of the limbs are spaced apart and at opposite sides of the interconnecting part and are capable of being pressed towards each other in a direction transverse to the interconnecting part by the fingers of one hand in order to loosen the respective coils to enable their location over, or removal from, the respective screw action connectors.
