DIN 929 Hexagon Weld Nut

DIN 929 is a German standard for steel hexagon weld nuts. These nuts join parts by welding and are used in machine building, construction, the automotive industry, and equipment manufacturing.

Main characteristics

Weld nuts are made of carbon steel or A2 stainless steel. The shape is hexagonal, for ease of installation. The underside of the nut has projecting elements that allow it to be welded to a surface.

Welding creates a permanent joint resistant to mechanical loads. The size range allows you to select a nut for different applications.

• Strong fastening: welding provides a permanent joint.
• Load resistance: the design is intended for use under high mechanical loads.
• Installation speed: welded installation reduces time compared to other fastening methods.

DIN 929 nut sizes range from M3 to M16. As the nut size increases, the dimensions of the projections intended for welding also increase: the projection height for the sizes shown ranges from 0.25 mm to 1 mm. Full dimensional parameters are given in the table below.

Where to buy DIN 929 nuts
