A fastener with shaving inhibitor for fastening a material such as a metal sheeting panel to a substrate such as metal or wood. The fastener has a notch angled leftwardly with respect to an axis of the fastener, the notch having a first end and a second end, a leading face and a trailing face, each face having outer edges and a common edge at their intersection. At least one of the leading and trailing faces may be substantially planar but may have other shapes, such as concave. Leftwardly angled notch with faces having outer edges may attract and then cut shavings formed from material being installed, thereby reducing the quantity and/or length of shavings, prolonging the life of the material or the structure to which the material is fastened.

An anchor assembly structured for use in connection with ceiling or roofing structures for hanging industrial or commercial components, such as, for example, electrical conduits, heating units, water pipes for automatic water sprinkler systems, and the like. The anchor assembly is easy and quick to install, and also provides enhanced swivel capabilities or angular ranges of movement so as to accommodate various system and spatial requirements in connection with the suspension of the components. Suspension and lateral restraint systems are also disclosed.

A driver blade for use in a combustion-powered fastener-driving tool includes an elongate tubular body having a combustion end and a driving end, the combustion end being configured for attachment to a piston, and the driving end having a substantially solid cross-section. The tubular body is in fluid communication with a tool combustion chamber.

A threaded fastener comprises a first, primary thread lead, and a pair of second, auxiliary thread leads alternatively interposed between successive threads of the first, primary thread lead, except within the vicinity of the tip portion of the fastener so as to define space for accommodating debris generated during the self-tapping of the fastener into a workpiece. The fastener also comprises lobe members formed upon the primary thread lead so as to predeterminedly affect torque insertion and pull-out resistance values.
