The annular recess is formed by providing a cylindrical socket in the end of the head a and forming or securing at the centre a cylindrical boss b of equal, longer or shorter length than that of the socket. The striking piece is driven or screwed into the socket which is provided with circumferential ridges or screw thread on the peripheral face.
