Place the tee nut barrel into the hole from the back side of the workpiece, ensuring the flange is perfectly parallel to the surface. Seat the Prongs:
The most common material used, typically low-carbon steel (e.g., class 4.8 or similar) optimized for cold forming and stamping. din 1624 standard pdf

The specifies the requirements for metric tee nuts with prongs, which are widely used to create strong, reliable steel thread inserts in wood, plastic, and composite materials. This comprehensive guide covers the technical specifications, dimensions, materials, and installation procedures outlined in the DIN 1624 standard. 1. What is the DIN 1624 Standard?

Designed for fast, tool-free insertion by pressing or hammering into pre-drilled holes. Technical Review: Superseded Steel Strip (DIN 1624)
It has been by European (EN) and international standards, primarily DIN EN 10106 and DIN EN 10107 (grain-oriented electrical steels) and DIN EN 10165 for magnetic properties measurement. Can’t copy the link right now
Tee nuts consist of a flat flange with integrated prongs or claws and a long, internally threaded barrel. When driven into a pre-drilled hole, the flat flange sits flush against the material surface while the prongs dig deep into the wood substrate. This design prevents the nut from spinning or pulling out when a mating bolt is tightened from the opposite side. 2. Key Dimensions and Technical Specifications
