Title:
部品へとねじ込むことができるねじ
Document Type and Number:
Japanese Patent JP2012503154
Kind Code:
A
Abstract:
The invention relates to a screw which can be screwed into a component and which will resist further screwing into an internal thread within said component once a maximum torque has been reached. For this purpose, a screw body having an external thread is combined with a screw drive element which projects into a bore within said screw body and, within said bore, is connected to the screw body via static friction. At least part of this combination is made of a plastic material, with the static friction having the effect of a slipping clutch when a maximum torque acts on the screw drive element. The screw drive element is connected to the screw body via a ratchet in such a way that when the screw body is unscrewed from the internal thread within said component, turning said screw drive element will cause the ratchet to engage, thereby entraining the screw body.
