Various embodiments provide a fastener including a head, a shank connected to the head and having a tip, one or more helical thread formations extending outwardly from the shank, and wherein a bottom portion of the head includes a plurality of ribs that extend towards the tip of the shank and that are shaped to abruptly frictionally engage a surface of a first object being attached to a second object to create an immediate frictional torsional resistance of a desired force level to the tightening of the fastener. This frictional resistance is provided back to the tightening tool to inform the operator of the tightening tool that the head of the fastener has sufficiently engaged the first object and that further tightening or clockwise rotation of the fastener is unnecessary.

Threaded fastener

Various embodiments provide a post-to-beam fastener including a head, a tip, and a threaded shank connected to the head at a first end and the tip and a second end. In various embodiments, threaded shank includes a longitudinal axis extending from the head to the tip, and the tip includes a recess operable to removably receive a drill bit to the fastener.

Post-to-beam fastener

Various embodiments of a fastener driveable into a substrate are provided. The fastener includes a head, a shank, and a helical thread formation. Portions of the shank and helical thread formations may be tapered. The outer diameter of the shank may decrease in a direction away from the head. An outer diameter of the thread formation may increase in a direction away from the head. The head may include a plurality of extending ribs. The helical thread formation may be formed with a plurality of grooves that are respectively each partially defined by a straight cutting edge. These improvements reduce torsional failure of the fastener from over tightening.

The present disclosure provides a threaded fastener having a hybrid self-drilling tip or drill tip. The fastener includes a head, a shank connected to and extending from the head, a helical thread formation extending radially outwardly from part of the shank, and a self-drilling tip including a first tapered tip portion and a second tapered tip portion. The first tapered tip portion is connected at a first end to the shank and at a second end to the second tapered tip portion, and the second tapered tip portion terminates in a pointed end. The outer diameters of both tapered portions taper radially inwardly moving in the direction of the pointed end, which renders the fastener suitable for attachment to wood as well as for fastening two metal objects to one another.

Threaded fastener with a hybrid self-drilling tip

A self-drilling anchor assembly including a drill bit and an anchor positioned over and attached to the drill bit. In various embodiments, the drill bit includes a shank, a drill head integrally connected to one end of the shank, and a threaded tail integrally connected to an opposite end of the shank. The tail includes a mechanical engaging structure that is engageable by a tool to rotate the drill bit, and a helical thread formation to facilitate attachment of a securing device such as nut and washer to the tail of the drill bit. The anchor includes an elongated generally tubular body including an inner surface defining a longitudinally extending inner channel, and a head integrally connected to and extending from a first end of the body. The drill bit is configured to remain in the anchor and in the substrate after installation of the anchor assembly in the substrate.

Self-drilling anchor assembly

An anchor assembly including a threaded anchor and a threaded drive pin positionable in the threaded anchor, a method of using or installing the anchor assembly to attach a fixture to a substrate, and a method of removing or un-installing the anchor assembly from the fixture and the substrate to detach the fixture from the substrate.

Anchor assembly

A powered fastener driving tool such as a powder-actuated tool including a housing assembly including a side wall having a first outer section, a raised section, and a recessed section, the raised section including a rim that extends in an outermost plane of a side wall of the housing and a spring-loaded slidable power setting switch partially positioned in and partially extending from the housing. The spring-loaded slidable power setting switch includes a depressible button movable from a resting position in which an outer surface of the button extends outwardly beyond the plane in which the outer surface of the rim lies to a depressed position in which the outer surface of the button extends in a same or substantially same plane in which the outer surface of the rim lies.

Powered fastener driving tool

A measuring device that includes in various embodiments a self supporting object attacher and an electronic measuring system supported by the self supporting object attacher. The electronic measuring system is configured to determine or enable the determination of a distance of a space between a first object on which the object attacher is positioned and a second object spaced apart from the first object.
