  • Patent number: 11661963
    Abstract: A magnetic pin system includes a magnetic pin having a polymeric body including: a seating portion; a cylindrical-shaped insert portion integrally fixed to the seating portion; and a first locking wing and a second locking wing oppositely positioned about the insert portion with respect to the first locking wing and integrally connected to the insert portion. A metallic insert is fixed to the seating portion. The metallic insert is susceptible to a magnetic field applied to the metallic insert acting to co-rotate the metallic insert and the polymeric body to install and to remove the polymeric body from a fixed position. A magnetic coupler is positioned over the metallic insert and magnetically coupled to the metallic insert. The magnetic coupler is rotated to induce a 90-degree rotation of the magnetic coupler and thereby the metallic insert to lock the magnetic pin in the fixed position.
