Abstract: A safety device configured to provide an indication of potential issues associated with a retention nut via a nut cap movably attached to a base. The nut cap(s) can have an electronic sensor configured to acquire and store digital data associated with a corresponding nut. Nut cap(s) can be coupled with a nut rotation indicator configured to provide an indication of a rotation of a corresponding nut.

Abstract: Safety apparatuses for objects having at least one nut are disclosed. Contemplated apparatuses comprise a base, one or more nut caps, and one or more electronic sensors configured to acquire data related to a corresponding nut, wheel or tire. In some embodiments, a physical nut rotation indicator that can readily be observed by an operator is included, and a retention wall disposed on the base can operate in conjunction with the physical nut rotation indicator to block a rotation of a nut. Apparatuses are preferably configured to remain stable in harsher environments.
