Abstract: A device for securing an object to a ceiling includes a threaded rod, a bracket and a spring-loaded tab. The spring-loaded tab has a tab portion with an outer surface. The tab portion is rotatable about an axis perpendicular to the threaded rod. When the device is attached to the object and the object moves into an opening in the ceiling for installation to the ceiling, the tab portion is urged from an extended position to enable the object to pass through the opening. Subsequently, the tab portion returns to its extended position such that the object can be temporarily supported by the tab within the ceiling opening. The bracket is configured so that during a removal process, a portion of the bracket urges the tab portion inward from the extended position to enable the object to be removed from the ceiling opening.

Abstract: An over torque prevention device includes a cap a cap configured for attachment to and removal from a threaded fastening member. The cap has a first portion shaped to engage a head of the threaded fastening member and a second portion having a surface feature shaped to receive a driver tool for applying a torque to rotate the cap and the threaded fastening member. The cap is formed of a material that has a lower shear strength than the material of the threaded fastening member. When a driver tool is used to engage the surface feature of the cap and apply an increasing torque, the surface feature or other portion of the cap deforms at a torque limit value such that further application of torque to the threaded fastening member is prevented.
