The main materials for expanded rivet nuts are zinc-plated iron and stainless steel, making them a type of fastener used in sheet metal, thin plates, enclosures, and cabinets. What should we pay attention to when using expanded rivet nuts?

When selecting threaded inserts, it is essential to consider the thickness of the material being used and confirm the size range. The hardness of low-carbon steel plates must be less than 70 RB, and the hardness of stainless steel plates must be less than 80 RB.

2. The machinable iron surface is treated, the stainless steel is kept in its original color. Customers can order according to the model and specifications listed, or can also place special orders as needed.

3. The hole size of the plate must be machined within the tolerance of 0-+0.075mm, and it is recommended to punch the holes.

Installation must be achieved through "tension riveting," and must never be impacted into place.
