Brass Threaded Insert Nut

Custom Threaded Insert Nuts

Threaded Insert nuts are specialized fasteners designed to create secure threaded connections within specific materials or components. Their outer surfaces feature special structures--such as knurls, serrations, annular grooves, or reverse-threaded bands--that significantly increase friction and grip with the surrounding material, preventing loosening or rotation during use. Some designs also include flanges for enhanced connection stability.

Made from high-strength metals like carbon steel, stainless steel, or brass, insert nuts are categorized as follows:

Carbon steel insert nuts: Low cost and high strength, ideal for general industrial applications.

Stainless steel insert nuts: Excellent corrosion resistance, widely used in food processing, medical, and chemical industries.

Brass insert nuts: Offer both electrical conductivity and wear resistance, commonly applied in electronic device manufacturing.

These nuts are installed via press-fitting, screw-in, or ultrasonic methods into pre-machined holes, forming a tight fit with the base material. When a bolt is tightened, the axial load is transferred through the nut to the base material, ensuring reliable fastening. Compared to standard nuts, insert nuts save space, maintain surface aesthetics, and allow for easy assembly and disassembly.

Applications of insert nuts span a wide range:

In electronics, they secure circuit boards and buttons within plastic housings.

In furniture manufacturing, they enable high-strength joints in wooden parts.

In aerospace, they assist in assembling composite material components.

In automotive industry, they are often used in connections between rubber dampers and vehicle bodies.
