Abstract

A toggle bolt to be used, for example, to fasten components to a ceiling. The toggle bolt includes a bolt portion and a sleeve portion. The bolt portion is of standard construction and includes an elongated threaded shank and a head portion. The sleeve portion includes a threaded nut pivotally mounted within the sleeve. The sleeve is slotted on one end so that the bolt can be threaded into the nut and then positioned either aligned or crosswise relative to the sleeve. A leaf spring portion in the sleeve biases the sleeve into the crosswise position so that the aligned position is maintained only while the sleeve is pushed through a hole in the ceiling and upon clearing the hole assumes the crosswise position.
