Abstract
Insulation screw adapted to be inserted by a mounting device into insulation material, where the insulation screw comprises a body provided with at least one thread, where the tip of the body is pointed, where the outer diameter of the head is equal to or smaller than the outer diameter of the body and where the lead pitch of the thread is at least 30 millimetres. An insulation screw can be driven completely through a central opening since the insulation screw does not have a protruding head. The insulation screw is provided with a thread and the opening of a mounting device is provided with a corresponding threaded portion, such that the insulation screw is screwed into the insulation material by a non-rotating pushing force.

An insulation screw adapted to be inserted by a mounting device into insulation material, the insulation screw comprising:
- a body provided with at least one thread;
- a pointed tip at one end of the body, which is configured to be inserted into the insulation material by the mounting device;
- a head at the other end of the body, comprising a pushing surface configured to be pushed by a drive head of the mounting device to insert the insulation screw into the insulation material,
- wherein a dimension of the pushing surface is smaller than a cross section of the body,
- and
- wherein a lead pitch of the at least one thread of the insulation screw is at least 30 millimetres,
- wherein the at least one thread is offset from the pushing surface at the other end of the body.
A method for inserting an insulation screw having a lead pitch of at least 30 millimetres into insulation material using a mounting device comprising an opening provided with a threaded portion corresponding to a thread of the insulation screw, the method comprising:
- placing the insulation screw inside the mounting device such that a tip of the insulation screw is arranged at the opening of the mounting device,
- placing the mounting device to bear against the insulation material,
- driving the insulation screw completely through the opening of the mounting device.
