Rivet nuts AN 320 M4 × 10 mm — reduced countersunk flange, 5 pieces
Open-end rivet nuts for setting internal threads in thin components using a rivet-nut tool. The body is cylindrical and longitudinally knurled. Knurling limits rotation of the item in the hole. The reduced countersunk flange has an angle of 120° and a small diameter of 7 mm. AN 320 is the catalogue designation of this design.

Material, thread and coating
The applicable catalogue column specifies unalloyed (carbon) steel EN 10025, ISO metric thread with tolerance 6H according to ISO 965 and electroplated zinc A2K of thickness 5 µm, with Cr3+ passivation, according to ISO 4042. White zinc plating matches the existing offer's finish. These are catalogue requirements; they are not a test certificate for a specific batch. No unstated exact steel grade, hardness, setting force or load capacity has been assigned. Tolerances for the remaining dimensions require confirmation.
Selection and installation
For this version, grip range g is 0,5–2,0 mm, and the recommended installation hole has a diameter of 6,1 mm. The documentation identifies these as manufacturer data and recommends trials to select the rivet nut and setting parameters. Hole and flange-seat preparation must suit the intended material and tool. A cylindrical flange geometry or a different cone angle must not be used for this purpose.
During setting, the deformable body section clamps the material. The open-end version does not provide a sealed closure.

Scope of delivery and weight
The price covers a pack of 5 rivet nuts AN 320 M4 × 10 mm, zinc-plated steel. The existing weight assigned to the offer 0,15 kg has been retained without recalculation. It is not a confirmed catalogue weight for a pack of five pieces.
The in-house product and packaging graphics are illustrative. They do not document the exact number of pieces or the delivery carton. The diagram shows the item before setting; thread and knurling length are schematic. This is not manufacturing documentation.
