    Abstract: A disk clamp for clamping a plurality of disks within a disk drive has a single fastening hole located at its symmetrical center sized to pass the shaft of a screw having a head diameter larger than the fastening hole. The screw fastens the disk clamp to a motor hub supporting the plurality of disks. The disk clamp has a moat around the fastening hole, at a maximum diameter that is smaller than the head diameter of the head on the fastening screw. The moat may be circular, have spike trenches angled toward the fastening hole, or be spiral. The diameter of the spiral moat decreases in a clockwise or counterclockwise direction toward the fastening hole. The midsection of the disk which the screw head covers is biased at a negative angle toward the fastening hole forcing particles generated during assembly toward the fastening hole of the disk clamp.

    Abstract: A system for fastening a head stack to a hard drive base assembly (HDBA) comprises a threaded head stack pivot (THSP) having a socket defined therein. The socket comprises a proximal portion defined by inner walls arranged parallel to a longitudinal axis of the socket and a distal portion having a width less than a width of the proximal portion and forming a ledge adjacent to the proximal portion. The system also comprises a bit for driving the THSP into an HDBA. The bit comprises a head comprising contact surfaces arranged parallel to a longitudinal axis of the bit and tapered surfaces extending from respective contact surfaces to a distal end of the bit. The bit is configured to engage the ledge at seams formed between adjacent tapered surfaces and to engage the inner walls with respective contact surfaces when driving the THSP into the HDBA.
