Publication number: 20180080493Abstract: A self-fastening threaded insert is described, with respect to a slab of building material, comprising a bearing element with respect to the slab, a deformation element adapted to interact with the slab, and a supporting element cooperating with the bearing element. The deformation element is deformed due to the effect of an external load transmitted by the supporting element, and is adapted to transmit to the slab forces which are perpendicular to an application force of the external load to be able to fasten the threaded insert to the slab. A process for assembling such threaded insert is also described.Type: ApplicationFiled: April 7, 2015Publication date: March 22, 2018Applicant: Specialinsert s.r.l.Inventor: Piero Arduini
