ABSTRACT:
A screw-nut arrangement for securing two or more members together is provided with a unique design for a locking nut insert. The locking nut insert has a straight knurled cylindrical portion with an end surface which abuts a shoulder in a counterbore of a through hole and a gripper retainer ring mounted adjacent to the knurled portion. The retainer ring is fabricated from strip material with grippers punched outwardly and is formed into an annular sleeve which fits around the locking nut insert. The retainer ring is held onto the locking nut by a collar.
