Abstract

PURPOSE: To make manufacture and working simple and reduce the cost of production by working an annular body which is made by slicing a metallic pipe in its diametral direction under pressing in sandwiching thereby forming the head part for a bolt.
CONSTITUTION: A pipe 1 made of mild steel is sliced to a prescribed width B, to make an annular body 2. This body is worked under pressing in sandwiching in its diametral direction, whereby a cylindrical part 3 is formed in its central part. The parts of the body 2 continuous to both sides thereof are folded over to form wing parts 4 and provide a wing-shaped head part 5. Then, the head part 9 of a screw shaft 6 continuously provided with a collar part 8 and the head part 9 to tht top end of a screw part 7 is fitted to the cylindrical part 3 of the wing-shaped head part 5, and the wing-shaped head part 5 and the screw shaft 6 are coupled by welding, calking or other suitable joining means, whereby the wing bolt is completed. Thus, the cost of material is low, there are no scrap losses and yet the manufacture and working are made simple.
