Custom-made standard and non-standard nuts of various materials and specificatio

We specialize in providing custom-made nut solutions covering both standard and non-standard categories, tailored to meet diverse industrial application needs. Our services support material customization, specification adjustment, and structural optimization, ensuring each product aligns with client requirements for performance, compatibility, and environmental adaptability. Below is a detailed overview of our custom nut offerings.

 Standard Nuts (Customizable per International Standards)

• Metric System: Compliant with ISO (ISO 8673, ISO 4032), DIN (DIN 934, DIN 935), GB (GB/T 6170, GB/T 6172) standards, available in coarse thread (M1-M64) and fine thread (M8×1, M10×1.25, etc.) options.
• Imperial System: Conforming to ASME (ASME B18.2.2), ANSI (ANSI B18.2.2) standards, with thread sizes ranging from #0-80 to 4"-4 UNC/UNF.
• Typical Standard Types: Hexagonal nuts (full thread/half thread), slotted nuts, castellated nuts, flange nuts, lock nuts (nylon-insert, all-metal), and thin nuts.

Non-Standard Nuts (Tailored to Special Requirements)

• Special Structures: Custom异形 (special-shaped) nuts (e.g., square, oval, triangular cross-sections), nuts with integrated washers/flanges, blind-hole nuts, and nuts with custom drilling/tapping (e.g., cross holes, axial holes).
• Non-Standard Threads: Custom pitch (e.g., 1.5mm non-standard pitch for M12), left-hand threads, trapezoidal threads (Tr), and buttress threads (BU) for heavy-load applications.
• Size Optimization: Ultra-small nuts (M1-M3 for electronic devices), large-diameter nuts (M64-M120 for heavy machinery), and thin-walled nuts (wall thickness ≥0.8mm) for limited-space installations.

Material Customization Options

 Core Specification Ranges

• Size Range: Inner diameter M1-M120 (metric), #0-80 to 4" (imperial); thickness 1mm-50mm; hexagonal opposite side width 2mm-150mm.
• Thread Precision: Class 4H-6H (metric internal thread), Class 2B-3B (imperial internal thread), supporting high-precision threads for aerospace (Class 5H).
• Mechanical Performance: Tensile strength 400 MPa-1200 MPa; hardness HV 150-HV 450; torque retention rate ≥90% after 1000 vibration cycles (for lock nuts).

 Key Customization Dimensions

• Surface Treatment: Customizable based on corrosion resistance needs, including zinc plating (yellow/white/blue, salt spray resistance ≥200h), galvanizing, Dacromet (salt spray resistance ≥1000h), electrophoretic coating, and passivation (for stainless steel).
• Structural Details: Customizable chamfer size (C0.1-C2.0), fillet radius, and weight reduction grooves (for lightweight requirements).
• Performance Requirements: High-temperature resistance (up to 1000°C for Inconel materials), low-temperature resistance (down to -269°C for stainless steel 316LN), and anti-loosening performance (passing DIN 65151 vibration test).

Core Customization Advantages

• Full-Demand Coverage: From standard size adjustments to one-of-a-kind non-standard structural design, we provide turnkey solutions without limiting customization scope.
• Strict Quality Control: Each customization project undergoes material inspection (spectrometer testing), thread inspection (thread gauge, 3D scanning), and performance testing (tensile, fatigue, corrosion tests) to ensure compliance with client standards.
• Fast Response Cycle: Standard nut samples are delivered within 3-5 working days; non-standard nuts with structural design take 7-15 working days for prototyping, and mass production lead time is 15-30 working days.
• Professional Technical Support: Our engineering team (with 10+ years of fastener customization experience) provides design optimization suggestions, such as material selection and structural improvement, to reduce client costs.

Customization Process

1. Demand Communication: Clients provide requirements (standard number/structural drawing, material, performance, quantity, delivery time) or application scenarios; our team clarifies details and provides preliminary solutions.
2. Program Design & Quotation: For non-standard products, we complete 2D/3D drawings (AutoCAD, SolidWorks) for client confirmation, then issue a detailed quotation including material cost, processing fee, and testing fee.
3. Prototype Production & Testing: Produce 1-5 prototypes, conduct dimensional and performance testing, and provide a test report; adjust the prototype based on client feedback until it meets requirements.
4. Mass Production & Delivery: After prototype confirmation, arrange mass production with full-process quality monitoring; deliver with a quality inspection report and material certificate, supporting sea, air, and express delivery.

Typical Application Fields

• Automotive & Transportation: Custom flange nuts for chassis, high-strength alloy nuts for engines, and corrosion-resistant stainless steel nuts for automotive exhaust systems.
• Aerospace & Defense: High-precision titanium alloy nuts for aircraft components, high-temperature Inconel nuts for rocket engines.
• Industrial Machinery: Large-diameter alloy steel nuts for wind turbine main shafts, thin-walled non-standard nuts for textile machinery.
• Electronics & Electrical: Ultra-small stainless steel nuts for circuit boards, brass nuts for electrical enclosures.
• Construction & Infrastructure: Hot-dip galvanized carbon steel nuts for bridge steel structures, corrosion-resistant nuts for marine engineering.
