Abstract

PURPOSE:To reduce loss of material such as cutting waste and to simplify manufacture by crushing the required site of a round bar member by pressing to form an axial part and rolling a screw, cutting the axial part to provide a plurality of bolts with an axial part on one end. CONSTITUTION:The central part of a round bar member 1 is pressed by a press machine to form an axial part 2 of a square section and a square screw 3 is provided by a rolling die on the outer circumferential surface of the round bar member 1. Then, the center part 4 of the axial part 2 is cut to obtain two bolt members 1a, 1b having axial parts 2a, 2b on one end. Edge parts 5 having a section of triangular pyramid are provided by pressing on the front end part on the opposite side of the axial part 2. Four grooves 6 to send liquid bonding agent along the axial direction on the threaded surface on the outer circumferential surface of the bolt member 1a are formed by a pressing machine through bending operation. A spiral groove 7 is obtained by combining four grooves 6 through bending operation. A square bearing plate 8 is fitted to the screw part 3 of the bolt member 1a and nuts 9, 10 are screwed in to obtain a lock bolt 11.
