Abstract: A spindle nut assembly includes inner and outer nuts having corresponding beveled surfaces. The inner nut is tightly threaded onto an end of a spindle and is positioned to achieve a desired endplay setting. The outer nut contacts the inner nut at an oblique angle via the beveled surfaces, which squeezes the inner nut more tightly onto the spindle while still maintaining the desired endplay setting.

Abstract: A nut member has first and second end faces and corners, and is formed with a plurality of protrusions, each of which is disposed at a respective corner and each of which has a lateral inner face that extends from the second end face, and a plurality of recesses, each of which is indented inwardly from a respective corner and each of which is defined by a recess-defining wall. The recess-defining wall has a lateral outer face that extends from the first end face. Each protrusion is received in and meshes with a respective recess, and the lateral outer face is in face-to-face contact with the lateral inner face when two of the nut bodies are stacked and are tensioned on a screw bolt.

Abstract: A shrouded jam locknut including a body member of frustoconical configuration having a larger base and a smaller base, a recess extending inwardly into the body member from the larger base and terminating at a shoulder for bearing against a nut in locking relationship therewith, a threaded bore extending inwardly into the body member from the shoulder for receiving the end of a threaded shank, a skirt surrounding the recess and terminating at an annular edge, and a key-receiving recess in the smaller base.

Abstract: A lock nut arrangement formed of a first and second generally C-shaped nut member which are joined together in a manner allowing limited axial movement and free rotation relative to one another about the axis were two members were initially threaded to central openings. The nut assembly may be radially installed on a threaded lock and locked thereon by rotating the nut members relative to one another. A lock nut is manufactured by first forming a first and second nut blanks, axially pressing the nut blanks together, clamping the nut blanks and threading the central bore, rotating the nut blanks relative to one another a predetermined distance and slotting the nut blanks.
