Abstract: The fastener of this application is designed to facilitate the insertion of rotating power driven tools into the fastener recess. The recess of this fastener generally uses spirally configured driving surfaces and is formed in a counterbore in the upper surface of the fastener. The driving lobes have upper surfaces that are depressed a distance into the counterbore. A ramp surface is formed on each of the upper surfaces that causes a spinning bit to fall into the recess in an engaged manner. The ramp surfaces are constructed with both removal and installation ramp portions.

Abstract: Interference surfaces are constructed on inner transition surfaces between wings of a fastener having a spiral recess. A portion of the transition surface is tapered to provide the interference. A standard driver for a spiral recess will engage the interference surface to create a “stick fit” engagement. The punch is formed using a wire EDM operation to construct tapered surfaces within the die cavity of a hob. The hob is machined down to obtain the desired depth, which is measured up from a gage spot indicative of the sticking point.

Abstract: A fastener for securing particle or bulge producing materials, a method of manufacturing the fastener, and a method of using the fastener are provided. The fastener has a thread on a shank, and a knurled portion disposed between the thread and a head. The fastener also may have at least one flute in the knurled portion, and may have at least one rib on the lower surface of the head. In use, the method is accomplished by inserting the fastener, by rotation, into a particle or bulge producing material, and producing particles or a bulge. Then, the method provides for transporting at least some of the particles from the particle producing material via the at least one flute, and securing the particle producing material to a base material. In a bulge producing material, the method provides for displacing the bulge into the material.

Abstract: A package for a plurality of products, having a closed container having a container wall, the wall defining a cavity for holding the products, and the wall having a product holder adapted to hold at least one selected product in a position visible from outside the container. The holder is an inwardly and/or outwardly opening recess formed in the wall, and the at least one selected product is positioned in the recess. The holder includes an outer member restraining the selected product to the outwardly opening recess, such as a packaging label, having a transparent portion forming a viewing window for viewing the selected product. In yet another aspect, the plurality of products in the cavity may be identical primary products, such as screws. The selected product may be different from the primary product, such as a driver bit for driving the screws.

Abstract: A fastener for securing remnant-producing materials, a method of manufacturing the fastener, and a method of using the fastener are provided. The fastener is configured such that in use any remnants or slivers produced by rotation of the fastener are forcibly driven into the surface of the material. In one aspect, the fastener has two separate threaded portions, a first or lower threaded portion and a second or upper threaded portion. The threads on the lower threaded portion have a pitch that is different from the threads on the upper threaded portion. In one embodiment, the lower threaded portion threads have a larger pitch than the threads on the upper threaded portion. In use, after the lower threaded portion is completely inserted into the material, the upper threaded portion of the fastener enters the material.

Abstract: A fastener is described having a head formed with a recess which accommodates a square head driver, symmetrical drivers, such as PHILLIPS™ style drivers, asymmetrical style cross head drivers, such as POZIDRIV® style drivers, and combination square and cross drivers without compromising performance of the drivers.

Abstract: Recessed head fasteners are provided with a configuration by which the force applied by the blades of the driver to the recessed wings is applied at the radially outer regions of the wings. The wings of the fastener recess may be provided with torque pads at the outer regions of the wings adapted to engage the outer portions of the driver blades. The torque pads may be defined by relieved regions on the drive walls of the recess wings. The relieved regions are formed to avoid contact with the driver blades. Stabilizing ribs also may be defined at the radially inward regions of the drive walls. A recess engageable driver may include a plurality of radially extending ribs configured to promote engagement of the ribs with the most radially outward regions of the recess drive walls. The driver and the recess are compatible with each other as well as with otherwise corresponding conventional recesses and drivers that do not incorporate the invention.

Abstract: A spiral drive system for threaded fasteners includes driver-engageable surfaces on the head end of the fastener in which at least some of the driver-engageable surfaces are defined by a spiral segment configured to maximize torque transmission while spreading the driving load over a broad driver-fastener interface to reduce the risk of development of high stress regions. Drivers and related tooling also are disclosed.

Abstract: A driver bit and a driving tool having a plurality of projections formed on at least one surface of the shank portion/driving portion of the bit/tool to retain the bit in a bit holder, or to retain a socket or the like on the driving tool. The projections are formed such that the geometric envelope of the bit is within the tolerance of the bit holder, so that the bit can be used with standardized holders. When torque is applied to the bit or driving tool, the projections engage the inner surface of a standardized holder/socket, thereby retaining the bit/socket.
