Abstract: A torque retaining device for preventing unitary rotation of a nut and a fastener extending through two parts to be connected is provided. The torque retaining device includes an engagement portion for connection to one of the nut and a fastener head and an elongated portion for rotationally catching on one of the parts that the fastener is to be extended through. The engagement portion includes a wall having an inner side that defines a cavity for placement of the fastener head or nut and is shaped rotate with the fastener head or nut. At least one flexible member extends radially inwardly from the inner side of the wall for holding the fastener head or nut in the engagement portion.

Abstract: An improved fastening device includes a shank portion with a first end and a second end disposed from the first end. The fastening device includes a head portion disposed adjacent the second end of the shank portion The head portion of the fastening device includes a lower perimeter adjacent the second end of the shank portion, an upper perimeter disposed away from the lower perimeter and a body portion extending between the lower perimeter and the upper perimeter. The head portion is configured to engage a standard hex-shaped socket. The lower perimeter of the head portion has a generally hex shape and the upper perimeter has a different shape than the lower perimeter.

Abstract: A method for fabricating a fastener and washer assembly wherein the washer is permanently retained on the fastener by an annular raised portion on the shank of the fastener. The annular raised portion and the inner diameter of the washer are mutually formed so as to promote elastic deformation of both the raised portion and the washer when the washer is forced over the raised portion to be retained on the fastener. The method allows the fastener and the washer to be fully fabricated and processed prior to assembly, including such desirable steps as heat treating and plating of both the fastener and the washer. The annular raised portion is formed by a pair of converging annular surfaces which define a predetermined diameter. The washer has an inner diameter surface having a pair of chamfered edges. The washer is assembled onto the shank of the fastener by forcing the chamfered edge of the washer against and past the annular raised portion.
