Knurled Brass Insert Nuts

Knurled Insert Nut Manufacturer

Custom precision CNC-turned knurled brass insert nut, a high-precision mechanical fastening component manufactured through automatic lathe turning and knuring processes. As a specializedmachine-turning brass part, this component combines the excellent material properties of brass with precision machining technology, delivering reliable locking and load-bearing performance for a wide range of industrial and commercial assembly applications.

Wanda-an knurled brass insert nuts are produced strictly following ISO 2766 precision tolerance standards, with uniform knurling texture, consistent thread matching, and stable dimensional accuracy that meets long-term use requirements. Compared with injection-molded or stamping-formed insert nuts, our CNC-turned brass inserts have higher strength, better corrosion resistance, and more precise dimensional control, making them ideal forhigh-demand fastening scenarios.

Precision CNC Turning and Knurling Process

This product is fully completed through automatic lathe one-forming processing, which has higher production efficiency and dimensional stability than manual processing

1. Raw material cutting: Cut brass rods into specified blanks according to the product length requirements.

2. CNC turning: Turn the outer circle, step, and inner hole of the blank to ensure that the dimensional tolerance is controlled within the range required by the customer.

3. Inner thread processing: Tap internal threads of corresponding specifications (common specifications are M2, M3, M4, M5, M6, M8, and can support customized non-standard threads).

4. Outer knuring processing: Knurl the outer surface to increase the friction between the insert nut and the embedded substrate, prevent the nut from slipping or rotating after embedding, and improve the overall fastening strength.

5. Surface treatment: After processing, it goes through processes such as deburring, cleaning, and surface passivation to ensure a burr-free, smooth surface that meets assembly requirements.

6. Precision inspection: Each batch of products undergoes 100% dimensional inspection and appearance inspection, and only products that meet the tolerance requirements can leave the factory.

Main Application Scenarios

Precision knurled brass insert nuts are widely used in various industrial and consumer fields because of their excellent performance

1. Plastic product assembly: Pre-embedded in plastic casings, brackets, and structural parts to provide reliable internal thread fastening points, widely used in home appliances, electronic product casings, auto parts, and sports equipment.

2. Furniture and wood product manufacturing: Embedded in wooden furniture, solid wood doors and windows, and wooden decorative parts to replace traditional wooden embedded nuts, which have higher strength and is noteasy to loosen.

3. Electronic and electrical industry: Used in connectors, terminal blocks, equipment casings, and power distribution devices, taking advantage of the conductivity and corrosion resistance of brass to improve the safety and service life of the product.

4. 3C digital products: Used in the internal structure of mobile phones, tablets, laptops, and smart wearables to achieve lightweight and high-strength internal fastening.

5. Medical equipment: Because brass is easy to sterilize and has good corrosion resistance, it is used in the structure of various portable medical devices and diagnostic equipment.

6. Automobile and motorcycle manufacturing: Used in interior decoration parts, electronic accessories, and assembly structural parts to meet the requirements of vibration resistance and long-term use stability.
