Rivet nuts AN 322 M4 × 11 mm — hexagonal, zinc-plated steel, 5 pieces
Open-end rivet nuts for setting internal threads in thin components using a rivet-nut tool. The shank has a hexagonal section with smooth flat surfaces and engages a hexagonal hole. This shape limits rotation of the item in the hole. The flange is round, cylindrical and flat. AN 322 is the catalogue designation of this design.

Material, thread and coating
The applicable catalogue sheet 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, not a test certificate for a specific batch. Exact steel grade, hardness, setting force, torque and load capacity have not been stated; no values have been assigned. Tolerances for the remaining dimensions require confirmation.
Selection and installation
For this version, grip range g is 0,25–2,0 mm. The data sheet specifies hexagonal hole with width across flats 6,1 mm. Dimension s1 = 6 mm refers to the rivet-nut body. Hole dimension 6,1 mm must not be interpreted as a round-hole diameter. The documentation identifies the grip range and hole as manufacturer data and recommends rivet-nut and setting-parameter selection trials on the intended material.
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 322 M4 × 11 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 in-house dimensional diagram follows the layout of the applicable catalogue sheet; thread and section are schematic. The diagram is for product identification and is not manufacturing documentation.
Frequently asked questions
How many pieces does the price include?
The price covers one pack of five rivet nuts.
Does length 11 mm include the flange?
Yes. In AN 322, nominal length l is measured from the flange face to the opposite end. Height k is not added to it.
What shape are the body and flange?
The body is hexagonal, with width across flats s1 = 6 mm. The flange is round, cylindrical and flat, with diameter d2 = 9 mm and height k = 1 mm.
What hole and material thickness does this version suit?
The data sheet specifies a hexagonal hole with width across flats 6,1 mm and grip range 0,25–2,0 mm. Selection and setting parameters must be confirmed by trials on the intended material.
