FIELD: engineering industry. ^ SUBSTANCE: present invention pertains to engineering industry and may be used in welding. Mounting element consists of a bolt that has outer surface mainly parallel to longitudinal axis, namely coaxial to it, and performed with possibility of its insertion in construction part drilled hole or at least more preferably two construction parts. Bolt is made from wear resisting ceramic material, at bolt front end there is metal tip. The end of the tip contacts with bolt groove and is connected with it. At bolt front end there provided is connecting zone that covers some part of bolt length. In the mentioned zone the end and the groove are connected between themselves. Between tip front part axially projecting from the bolt and the bolt itself there provided is transition zone tapering towards front part. Mounting element has stepped outer contour, front part has maximum outer diametre that is smaller than bolt outer diametre by some specified value. ^ EFFECT: provision of bolt manufacturing economical efficiency and electric isolation during mounting element use. ^ 9 cl, 2 dwg |
