An anti-theft locking bolt assembly is disclosed. The assembly comprises an anti-theft bolt threadedly attachable to an article to be protected, a bolt cap snugly fitting into a bore on the head of the anti-theft bolt, a lock cylinder housing at least partially rotatably connected to the head of the anti-theft bolt, the lock cylinder housing configured to cover the bolt cap and a locking cylinder and to provide means to prevent removal of the bolt cap. The anti-theft locking bolt assembly is suitable to lock a vehicle wheel and also to replace a spark plug of an combust engine to prevent unauthorized use of the vehicle.

Lug nut locking systems, including s for securing lug nuts on a wheel of a motor vehicle comprising a frame with ratcheting apertures. In some embodiments, the device has a pair of supports that fit over the wheel's lug bolts and underneath the frame. In other embodiments, the device comprises uniquely configured securing caps that fit over the lug bolts. In still other embodiments, the device comprises a plurality of protective covers that fit over the securing caps.

The present invention relates to a novel safety device for motor vehicles wheels, in particular a device for locking the wheel nuts, able to effectively prevent their rotation and consequent spontaneous unscrewing, which may cause serious accidents.

A wheel nut indicator 10 includes an attachment section 12 for fitting to a wheel nut/lug nut of a wheel and a pointer section 14 extending radially away from the attachment section 12, the wheel nut indicator 10 being provided with a changeable secondary indication means which is moveable between a first position (FIG. 1) for indicating a first status, and a second position (FIG. 3) for indicating a second status.

A security fastener assembly is provided with a cap having a standard tool bearing surface and an attachment portion formed opposite the tool bearing surface. A fastener body has a mating attachment portion formed at a first end along which the cap is secured and a keyed security feature formed adjacent the mating attachment portion. A second end of the fastener body has a threaded fastener portion for securing the fastener assembly to a vehicle. The threaded portion of the fastener body is installed with rotation in a first direction. Engaging the tool bearing surface of the cap and rotating in a second direction opposite the first direction does not rotate the threaded portion of the fastener body. The fastener body is removable with the keyed security feature.

Implementations disclosed and claimed herein provide systems and methods for identifying and mitigating lug nut loosening. In one implementation, an indicator body of an indicator has a top surface connecting a front surface and a back surface. A first side of the indicator body is disposed opposite a second side of the indicator body. A receiver extends from the top surface into an interior of the indicator body. The receiver is configured to form a translational relationship of the lug nut with the indicator through a mating fit of the lug nut within the receiver. The translational relationship generates a corresponding rotation of the indicator body in response to a rotation of the lug nut. The corresponding rotation of the indicator body provides an indication that the lug nut is loose.

A locking device for car wheels is disclosed to prevent unauthorized removal of the wheels. The device includes a locking unit that allows covering of special bolt heads by covering wings. The locking module can be further covered with a covering plate. The system provides multiple layers of protection to the wheels and considerably lengthens the time required to remove the wheel without proper keys.

A wheel hub safety device is for a vehicle having a hub and a wheel. The hub having a plurality of opposing equiradially disposed wheel bolts. The wheel having a plurality of opposing equiradially disposed holes spaced for mating engagement with the wheel bolts on the hub. The wheel is configured for attachment to the hub through use of a plurality of lug nuts. The wheel hub safety device has a housing and a plurality of lug nut rotation detectors. The housing is for housing the plurality of lug nut rotation detectors, at least one sensor and a transmitter.

A security fastener assembly is provided with a cap having a decorative bearing surface and a lower retention portion. A fastener body has: a threaded portion or securing the fastener assembly to a corresponding threaded feature on a vehicle; a stem opposite the threaded portion for receiving the cap, the stem having a security protrusion defining a distal end, an undercut formed adjacent the stem for cooperating with the lower retention portion of the cap, where the lower retention portion of the cap is secured in the undercut to maintain the cap on the fastener body; a keyed security drive feature formed between the threaded portion the stem portion where the fastener body is removable with the keyed security feature. Engaging the decorative bearing surface of the cap and rotating does not rotate the threaded portion of the fastener body.
