Abstract

1,147,722. Threaded studs. NEWTON INSERT CO. 21 Feb., 1967, No. 8094/67. Heading F2H. A threaded stud comprises a body 17, Fig. 1, having first and second external threaded portions, e.g. 19 and 20, each located on opposite sides of a locking key 18 which is drivable in an axial groove 22 to cut through the thread of the bore of a carrier part 12 in which the stud is to be screwed, the groove and key extending into the material of the body 17 to a depth radially inwardly of the major diameters of the threads of both threaded portions. The threaded portions 19 and 20 may constitute the opposite ends of a single, continuous screw thread or, as shown, be two distinct threads separated by an unthreaded portion 21. The groove 22 has an undercut cross-section at the location of the key shaped to retain the key and has a non- undercut cross-section at the location of the first threaded portion. The groove has a curved portion (26, Fig. 3, not shown) which enables engagement of a driving tool with an outer surface of the key. The key may have a generally triangular or circular cross-section.
