Abstract

559,838. Making bolts. NEWALL, A. P. Feb. 20, 1943, No. 2863. [Class 83 (ii)] A headed bolt-blank made from bar stock of from oversize stock exnominal diameter or truded down to nominal diameter has the shank cold extruded at 10, Fig. 2, to form a diameter suitable for taking a rolled thread and the central part cold swaged at 10a, Fig. 3, to form a waisted portion, or two portions separated by a part of the same diameter as 10b. The bolt is finished by rolling a screw thread on the end portion 10b. The manufacture is similar to that described in connection with studs in Specification 557,960.
