About the product
A rivet nut creates an internal M12 thread in thin sheet metal or a profile when there is access from one side only. It is inserted into the hole and set with a rivet nut tool: the tool engages the thread and pulls it towards itself, while the part of the shank behind the material deforms into a collar that clamps the material together with the head. Once the tool is removed, a ready-to-use M12 thread remains in the material. This model has a flat head with a diameter of 23 mm and a height of 2 mm, and a round knurled shank. The flat head stands proud of the material surface by the head height k. The knurled shank limits the rivet nut from turning in the hole.
Choose the rivet nut to suit the thickness of the material in which it will be set. The M12 × 23 mm rivet nut is intended for material with a thickness from 1.0 to 4.0 mm; for a different thickness, choose another size from the list of nearest sizes. Drill the hole to Ø 16.0 mm, which is 0.1 mm larger than the 15.9 mm shank diameter, and remove burrs.
The rivet nut is made of A4 stainless steel. Where chlorides are present, for example by the sea or a swimming pool, choose the material according to the exposure conditions and the design recommendations. According to the manufacturer's data sheet, it withstands a shear force of 9 800 N and a tensile force of 52 950 N. These are test results for the rivet nut itself – the load capacity of the joint depends on the material and thickness of the element and is set by the design. Sold in boxes of 250 pcs; each box weighs 4.08 kg.
Preparing the installation
- ✓Check the material thickness: it must be within 1.0–4.0 mm.
- ✓Drill a round hole Ø 16.0 mm (0.1 mm larger than the shank d2 = 15.9 mm); remove burrs.
- ✓Set with a rivet nut tool with a M12 nosepiece; the head should sit against the surface.
Important
The grip range applies to the total material thickness under the head. The flat head stands proud of the material surface by the head height k. The knurled shank limits the rivet nut from turning in the hole. The load capacity of the joint depends on the material and thickness of the element – it is set by the design.
