DIN73033

DIN 73033 is a German industrial standard that specifies requirements for threaded blind rivets, also known as nutserts or rivet nuts. These fasteners are designed to provide a threaded insert in materials that are too thin to be tapped directly or where a strong internal thread is required.

The standard defines the dimensional characteristics of these blind rivets, including their body diameter, grip range, thread size, and head style. It also covers material requirements, ensuring the rivets are manufactured from suitable metals such as steel, stainless steel, or aluminum to provide the necessary strength and corrosion resistance for various applications.

DIN 73033 blind rivets are installed by inserting them into a pre-drilled hole in the workpiece and then using a special tool to deform the rivet's stem. This deformation securely fastens the rivet in place, creating a durable threaded receptacle. They are commonly used in automotive manufacturing, aerospace, electronics, and general fabrication where a reliable and strong threaded connection is needed in sheet metal or other thin materials. The standard helps ensure interchangeability and consistent performance across different manufacturers.
