A screw includes a barrel-shaped central pin is surrounded by a cylindrical bore having a conical bottom. The cylindrical insert is seated in the cylindrical bore. The top surface of the central pin is lowered below the top surface of the head. The walls of the pin (4) are convex towards the insert. Manufacturing the screw includes producing the threaded part with the head with the cylindrical recess with the cone-shaped bottom. The cylindrical insert terminates at one end with a bevel with an inclination angle of =10-30. The insert is introduced into the cylindrical recess. The upper part of the insert protruding from head of the screw is pre-shaped. The pin is upset using an appropriate tool and simultaneously the top surface of the pin is lowered below the top surface of the head.

An electric contact formed from electric contact members that include a rivet contact including a head portion containing a contact material in at least a part of a surface, and a foot portion that is inserted into a terminal member while supporting the head portion, and the terminal member that has an insertion hole for the foot portion of the rivet contact to be inserted, and fixes the rivet contact. In addition, in the rivet contact, a flange portion serving as a caulking margin and wider than the foot portion is formed between the head portion and the foot portion, and a counterbore hole for fitting the flange portion is formed in the terminal member. The electric contact of the present invention is manufactured in a good adhesion state with the flange portion of the rivet contact caulked to the counterbore hole of the terminal member.
