Precision stainless steel nuts

Product Features:

Our company has specialized in supplying precision stainless steel nuts for many years. Over the years, we have consistently introduced advanced technology and professional testing equipment to provide customers with products that offer high precision, high stability, and strong adaptability. The following are the key features of our products:

We use 304 stainless steel because it has a tensile strength of ≥515 MPa and an elongation of ≥40%. This product is ideal for use in dry and mildly corrosive environments. In terms of processing, we utilize high-precision cold heading and CNC thread machining processes, achieving thread accuracy of ISO 4H/5g, while maintaining dimensional tolerances within ±0.02mm. This ensures a precise fit with the bolt and eliminates play after assembly, effectively enhancing the stability and reliability of the connection. Our products also undergo an electrolytic polishing treatment, achieving a roughness of Ra ≤ 0.8μm, resulting in a smooth and uniform appearance. This also reduces friction and assembly resistance during use. Our products are currently widely used in high-precision applications such as machinery manufacturing, aerospace, medical devices, and electronic equipment, and have earned high customer recognition.
