3D Round Wedge Nut Insert M6

This 3D-printable groove nut holds the screw head in the correct position in the profile when tightening and loosening the round cord system, thus preventing wear on the screw. While the clamping screws on the upper and lower profiles remain independently at the desired position – at the clamping angle – they slide downward on the side profiles. This groove nut reliably prevents this and is simply inserted into the profile together with the screw.
