I. Types of Stainless Steel Nuts Machining Capabilities

Hexagonal Nuts: Standard and non-standard hexagonal heads, suitable for general mechanical connections, available in thin, thick, and flanged types. Multiple Specifications

Locking Nuts: Nylon insert locking nuts, all-metal locking nuts, pressure point locking nuts, with anti-loosening function.

Round Nuts: Round outer diameter with groove or hole, used for positioning and locking parts on shafts.

Cap Nuts: Enclosed head structure, used for aesthetic or protective requirements.

Weld Nuts: With raised points or bosses for easy welding and fixing.

Custom Nuts: Various non-standard nuts, special-shaped nuts, and precision threaded accessories customized according to customer drawings.

II. Precise Matching of Materials and Applications

Austenitic Stainless Steel Nuts (304, 316, 316L): Excellent comprehensive corrosion resistance, suitable for food machinery. 316L contains molybdenum, providing stronger resistance to pitting corrosion, making it ideal for marine environments.

Martensitic Stainless Steel Nuts (410, 420, 440C): Can be heat-treated to achieve higher hardness, suitable for fastening applications requiring a certain degree of wear resistance.

Precipitation-hardening stainless steel nuts (17-4PH): Achieving ultra-high strength (tensile strength exceeding 1000MPa) through aging treatment while maintaining excellent corrosion resistance, suitable for aerospace, shipbuilding, and high-pressure equipment.

III. One-Stop Precision Manufacturing and Performance Enhancement Services for Stainless Steel Nuts

We have built a complete precision manufacturing chain for high-precision, high-strength stainless steel nuts, focusing on achieving a balance between thread accuracy and connection reliability:

Precision blank forming utilizes high-precision CNC lathes or cold heading machines to precision turn or cold-head stainless steel wire or bar stock, machining hexagonal shapes, end faces, and internal holes to establish precise machining benchmarks.

IV. Core Processes for Precision Thread Machining

Thread Turning: For non-standard or small-batch nuts, high-rigidity CNC lathes combined with precision threading tools are used for internal thread turning, ensuring thread accuracy and dimensional consistency.

Thread Tapping: For large-batch standard nuts, high-speed tapping machines combined with high-performance taps are used for internal thread machining, offering high efficiency and cost-effectiveness.

Thread Milling: For large-diameter or special threads, thread milling is used. It involves low cutting force and produces excellent thread surface quality, making it particularly suitable for difficult-to-machine stainless steel materials.

Heat Treatment and Dimensional Stabilization: For martensitic and precipitation-hardening stainless steels, we provide professional vacuum heat treatment services including quenching, tempering, and aging. Deformation is strictly controlled, and stress relief treatment is performed to ensure dimensional stability and mechanical properties.

V. Surface Treatment and Protection

Passivation: Passivation forms a dense oxide film on the surface, significantly improving corrosion resistance. This is a standard treatment process for austenitic stainless steel.

Electropolishing: While removing burrs, it achieves a bright, clean surface, further enhancing corrosion resistance and aesthetics.

From standard parts to custom-made parts, we are committed to becoming the most trusted manufacturing partner for customers in various industries in the field of stainless steel fasteners.
