  • Publication number: 20210129299
    Abstract: Mounting device for inserting insulation holders into insulation material, where the mounting device comprises a drive head adapted to drive the insulation holder through a central opening of the head portion of the mounting device, where the central opening is provided with a threaded portion, where the lead pitch of the threaded portion is at least 30 millimetres. The advantage of the invention is that insulation holders can be inserted into insulation material in an easy and cost-effective way. An insulation holder can be driven completely through the central opening since the insulation holder does not have a protruding head. The insulation holder is provided with a thread corresponding to the thread of the central opening, such that the insulation holder is screwed into the insulation material.
