FIXATION BY INSERTION When the inserts are tightened between the insert and the piece to be fixed, the resistance on a plate of soft materials such as polystyrene is limited to the resistance of the plate itself. During the screwing operation, the insert can be held in place by a flat key of 13 or a pliers, the pegs (rep3) then ensure the anti-rotational function. Installation (photo 3): 1. Screw the screw into empty to form the mesh in the insert to avoid exercising too much torque during screwing. 2 => Perform a pre-drill with a drill bit of a size smaller than that of the insert, hold the insert with a flat key of 13 or a pliers to start screwing. 3=> Screw enough to make the head of the insert slightly enter the material. Material: Wood screw of 2.6mm in 3 mm Screwdriver (Option: open end spanner of 13 or crowbar) Recommendation: Print in ABS FIXATION BY INSERTION The inserts proposed are not intended to bear loads, they have been realized for example to create a children's toy from a polystyrene plate or equivalent soft materials. The inserts are sunk into the material, they work on the principle of a harpoon, the placement of the screw between the teeth (rep 1) spreads the two flanges (rep 2) in the material. Installation (photo 4): 1. Screw the screw into empty to form the mesh in the insert to avoid exercising too much torque during screwing. 2 => Perform a rectangular pre-drill with a drill bit and a size smaller than that of the insert 3 => Sink the insert into the plate, the insert must be at least 5mm away from the surface of the plate 4 => Screw the screw in final position with minimum tightening. Important: The insert must be sufficiently sunk into the material, the top of the insert must be at least 5 mm away from the support surface, it must almost disappear visually. Note: The variant is faster to install but less effective. Material: Wood screw of 3 mm Recommendation: Print in ABS
