Modular packaging includes a solid state relay and a function module, wherein the function module comprises a housing containing a printed circuit board and an elevating screw. The elevating screw comprises a first end with an external threading and a second end with an external threading, where the elevating screw may be selectively altered between a first position and a second position within the housing. Related embodiments are disclosed.

A fastener assembly is provided. The fastener assembly includes a nut having an internally threaded portion and an annulus extending from the nut and configured for receiving the shank of an elongate fastener. A compression collar is configured for deflecting the annulus into at least one of fixed engagement with the shank or to impart a spring bias of the annulus against the compression collar upon tightening of the nut about a working surface.

A fastener includes an elongated shaft having a first end, a second end, and a shaft body, a head portion, and a threaded portion. At least one inner feed channel extends through the head portion and the shaft body and terminates proximal to the threaded portion. The fastener has a plurality of flutes formed along and circumferentially spaced around an outer surface of the shaft body and an outer surface of the head portion. Each flute has a first end and extends from a first location proximal to the threaded portion, along the outer surface of the shaft body, and radially outward along the outer surface of the head portion. The fastener further has one or more lateral feed channels formed laterally through the shaft body and connecting the inner feed channel to at least two opposing flutes on the outer surface of the shaft body.

A screw includes at least one helical thread with a peripheral edge having notched regions spaced apart by notch-free regions. An underside of a head of the screw includes projecting nibs.

A mold, punch and workpiece are provided. In a preferred embodiment, a tapering outer edge is provided, along with a plurality of rib sets arranged circumferentially about the outer edge, and a ramp. A ramp may be located to facilitate the removal of burrs. Various slot patterns may be provided or formed, including star-shapes/Torx® slots. Using the present invention, a driver bit may be more securely fit to the slot of a screw, for example, allowing the screw to be threaded into a machined part more securely and smoothly, reducing rocking, shaking or tilt.

Various embodiments include a fastening unit for fastening a tendon to a system. The fastening unit comprises: a head with a first opening; a shaft with a second opening and an external thread; and a channel extending from the first opening along the head to the second opening at least partly along the shaft. The external thread and the channel in each case accommodate the tendon.
