Hello
I have 6 mm thick sidewalls and I also have a lot of big holes that are not a problem, on the other hand I have M4 or M5 taps to do.
Obviously not possible in laser so I am looking for an off-the-shelf solution like clinching which requires holes that can be made in laser.
In my experience I have only used the clinching technique for thin sheet metal 2 mm or less.
What could you advise me, I don't want to make a special piece unless constrained and forced.
Regards zz
Thank you Fred, that's exactly what I need.
I didn't remember the no of this type of object 
You're a good you!
Be careful with the marriage of metals when choosing the inserts
Rivet nuts are available in several materials: zinc-plated steel, stainless steel and aluminum. Their selection depends on the nature of the support and the level of resistance sought. The corrosion resistance of the substrate will be influenced by the combination of the materials chosen.
- Steel Insert : Ideally used on a steel stand, it is also suitable for an aluminium stand. Its use is strongly discouraged on a stainless steel support. The steel rivet nut is less resistant to corrosion than those made of aluminum and stainless steel, however it has a better mechanical resistance .
- Aluminium insert: Ideal for an aluminium support but also suitable for a steel or stainless steel support. Perfect for assemblies requiring weight reduction.
- Stainless steel insert : Mainly suitable for stainless steel supports, it can be crimped on an aluminium or steel support.

Hello Zozo_mp,
I'll add that too =>https://www.vis-express.fr/ecrou-a-sertir-hexagonal-tete-reduite-acrth/11521-2601203-ecrou-a-sertir-hexagonal-tete-reduite-m10x19-acier-zingue-acrth.html?gad_source=1&gad_campaignid=17189502710&gclid=EAIaIQobChMIs5yj_f21lAMVOT8GAB3rXDiEEAQYASABEgKlgfD_BwE
But it will take an exagonal hole =>

Thank you for the nut and the advice on the harmony between the materials.
The insert suits me well because it's for M4 or M5. It is a question of attaching small laser-cut and folded legs, these legs hold very small micro-switches (16 x 28 x10) which are fixed in the legs by M3 holes. Since there is hardly any clamping effort, I would not take the hexa crimp nut. On the other hand, I retain the idea for another part of the system.
Thank you again for your good tips
You’re welcome

Hello @A_R
Since we're there!! They are also available to weld
Let's go one last one in the same vein 
(the first one for the small Ø, and the solder nut from M8 I would say has seen the nose)
Hi Scofield,
Indeed, I knew " fluopiercing " in my youth.
for the exhaust pipe tubes at Renault.

Excellent I didn't know
