Stainless Steel Special-Shaped Nuts

The stainless steel internal hexagonal blind hole nut is a high-strength fastener made of 304/316 stainless steel, featuring both corrosion resistance and aesthetic appeal. Its internal hexagonal design makes it easy to install with a hexagonal wrench, and the blind hole structure (with a closed bottom) can prevent dust and water from entering, making it suitable for applications requiring sealing or neat appearance. The surface can be treated with polishing, sandblasting, etc., and is widely used in medical devices, precision instruments, food machinery, and outdoor equipment. It has good anti-loosening performance, resistance to vibration, and resistance to acids and alkalis, and complies with standards such as GB/T and DIN. It also supports non-standard customization of size and surface treatment.

Product Features:

1. Material and Corrosion Resistance: Made of 304/316, it has excellent corrosion resistance and is suitable for humid, acidic, alkaline and high-temperature environments.

2. Structural Design Advantages: Blind holes (bottom sealed): Prevents dust and liquids from entering, enhances sealing performance, suitable for clean environments (such as medical and food equipment).

3. Hexagon Drive: Compatible with standard hexagonal wrenches, installation is convenient, has strong torque-bearing capacity, and is not prone to slip.

4. Anti-loosening and Shock Resistance Performance: The blind hole structure reduces the exposure of threads, lowers the risk of loosening.

5. Surface Treatment Process: Aesthetically pleasing, easy to clean, suitable for high-end equipment (such as optical instruments).

FAQ

Q1: How to choose between 304 and 316 stainless steel?

A1: 304 is suitable for general corrosive environments. 316 contains molybdenum and is more suitable for high salinity/chemical corrosive environments. For medical and marine engineering applications, 316L medical grade is recommended.

Q2: How is the installation torque determined?

A2: We offer an intelligent torque calculator: Just input the parameters (material/ specification/ lubrication status) to obtain the precise torque value. The standard torque for M6 is 8-10 N·m (dry installation)

Q3: What is the minimum order quantity?

A3: Customized products: 50,000 pcs minimum.
