Press Nuts (Broaching Nuts)

Description

Press nuts are used wherever a high degree of joint stability is required in thin-walled sheet metal or plastic parts. They are a very good alternative to nuts that are welded, brazed or welded to the component. Press nut that can obtain a high mounting strength thanks to the knurled portion under the neck.
Portion of the nut under the neck has a unique shape (knurled, grooved) and so a high mounting strength can be obtained.
Post-processing such as rust-proof processing, sputtering treatment for weld-on nuts, etc., not required.

Design and Installation:

Broaching nuts feature a knurled or serrated shank that allows them to be pressed into a pre-drilled hole in the host material. During installation, the knurled shank broaches, or cuts, into the material, creating an interference fit that securely locks the nut in place. This process ensures a durable and reliable threaded connection without the need for additional hardware or welding.

Advantages:

• High Joint Stability: The interference fit achieved through the broaching process provides a stable and secure joint, making these nuts suitable for applications requiring high joint integrity.
• Versatility: Broaching nuts can be used in a variety of materials, including glass laminates, epoxy, resin with paper, nylon, and canvas bases. They are also effective in materials too thin to support adequate threading, such as acrylic and polycarbonate panels.
• Elimination of Welding: By providing a mechanical attachment method, broaching nuts eliminate the need for welding, reducing potential issues like thermal distortion and material incompatibility.

Applications:

Broaching nuts are widely used across various industries, including:

• Electronics: Commonly applied in PCBs to provide strong threads for mounting components, reducing the risk of damage to the board and minimizing loose hardware within assemblies.
• Automotive and Aerospace: Utilized in thin-walled sheet metal or plastic parts where high joint stability is required, offering a reliable alternative to welded or brazed nuts.

Their ability to create robust threaded connections in challenging materials makes broaching nuts a preferred choice for engineers seeking efficient and reliable fastening solutions.
