제품 설명

Supplying bolts of various materials, surface treatments, and specifications, and supporting non-standard custom bolts.

We specialize in providing comprehensive custom-made bolt solutions tailored to diverse industrial application scenarios. Our services cover both standard and non-standard bolt customization, supporting personalized adjustments of bolt type, material, size, thread, surface treatment, and mechanical performance. With strict quality control and professional technical support, we ensure each custom bolt meets the compatibility, reliability, and durability requirements of specific applications. Below is a detailed overview of our custom bolt services.

Standard Bolt Customization (Compliant with International Standards)

We produce standard bolts in accordance with global industrial standards, with customizable parameters including material grade, surface finish, precision level, and packaging. Common standard systems and typical types include:

International Standards: Metric System: ISO (ISO 898-1), DIN (DIN 933, DIN 931), GB (GB/T 5782, GB/T 5783) for coarse/fine thread bolts (M1-M64).
Imperial System: ASME (ASME B18.2.1), ANSI (ANSI B18.2.1) for UNC/UNF thread bolts (#0-80 to 4"-4).

Typical Standard Bolt Types: Hexagon head bolts (full thread/partial thread), flange bolts (with integrated washer), countersunk head bolts, socket head cap screws, carriage bolts, and eye bolts. Customizable details include thread length, head thickness, and chamfer size.

Non-Standard Bolt Customization (Tailored to Special Demands)

For scenarios where standard bolts cannot meet assembly space, load-bearing, or environmental requirements, we offer end-to-end non-standard customization, including structural design, prototyping, and mass production. Key customization directions:

Special Structures: Custom-shaped heads (square, oval, triangular), bolts with integrated pins/studs, hollow bolts, stepped bolts (different diameter at head and shank), and bolts with custom slots/holes (cross, hexagonal, axial holes).
Non-Standard Threads: Custom pitch (e.g., M12×1.75 non-standard pitch), left-hand threads, trapezoidal threads (Tr), buttress threads (BU), and multi-start threads for high-efficiency assembly.
Size Optimization: Ultra-small bolts (M1-M3 for electronic devices), large-diameter bolts (M64-M150 for heavy machinery), and ultra-long bolts (length up to 3000mm for infrastructure).

Material Customization Options

Materials are selected based on application scenarios (corrosion resistance, temperature resistance, load capacity) and cost constraints, all complying with international material standards (ASTM, EN, GB). Common material options:

Material Category	Typical Grades	Key Properties	Suitable Applications
Carbon Steel	1018, 1045, SAE 10B38	Tensile strength: 400-1000 MPa; good machinability; cost-effective	General industrial machinery, construction, automotive non-critical components
Stainless Steel	304 (1.4301), 316 (1.4401), 316L (1.4404)	Excellent corrosion resistance (salt spray test ≥5000h for 316); temperature range: -200°C to 600°C	Marine equipment, food processing, medical devices, chemical pipelines
Alloy Steel	40Cr, 35CrMo, 42CrMo, SAE 4140	High strength (tensile strength ≥1000 MPa); good fatigue resistance; hardness: HRC 30-45	Automotive engines, wind turbines, heavy-duty machinery, aerospace accessories
Copper Alloy	Brass (H62, H65), Bronze (QSn6.5-0.1)	Good electrical conductivity; corrosion resistance; aesthetic appearance	Electronic equipment, electrical connectors, decorative hardware
Special Materials	Titanium Alloy (Ti-6Al-4V), Inconel 718, Hastelloy C-276	Extreme high-temperature resistance (up to 1200°C); lightweight; superior corrosion resistance	Aerospace, aviation, high-end petrochemical, nuclear industry

Core Specification Ranges

Size Range: Shank diameter M1-M150 (metric), #0-80 to 4" (imperial); length 3mm-3000mm; head diameter 2mm-200mm.
Thread Precision: Metric: 4g-6g (external thread); Imperial: 2A-3A; high-precision options (Class 5g) for aerospace and precision equipment.
Mechanical Performance: Tensile strength 400 MPa-1500 MPa; yield strength 240 MPa-1300 MPa; elongation ≥8% (for carbon steel); torque-tension consistency ≥95%.

Key Customization Dimensions

Surface Treatment: Customizable based on corrosion resistance and aesthetic needs: Zinc plating (yellow/white/blue): Salt spray resistance ≥200h; cost-effective.
Dacromet/Geomet: Salt spray resistance ≥1000h; environmentally friendly (RoHS compliant).
Hot-dip galvanizing: For heavy corrosion environments (e.g., bridges, marine engineering).
Electrophoretic coating/Powder coating: Custom colors and high corrosion resistance.

Structural Details: Customizable chamfer (C0.1-C3.0), fillet radius, head height, and shank straightness (≤0.1mm/m for precision bolts).

Performance Customization: High-temperature resistance (up to 1200°C for Inconel), low-temperature resistance (down to -269°C for stainless steel 316LN), and anti-loosening treatment (e.g., thread locking adhesive coating).

Core Customization Advantages

Full-Demand Coverage: From minor adjustments to standard bolts (e.g., thread length, surface treatment) to innovative non-standard structural design (e.g., integrated bolt-washer assemblies), we meet diverse customization needs.
Strict Quality Control: Each project undergoes multi-stage testing: Material inspection: Spectrometer analysis to verify material composition.
Dimensional inspection: 3D scanning, thread gauges, and calipers to ensure precision.
Performance testing: Tensile, fatigue, corrosion, and torque tests (compliant with ISO 898-1).

Fast Response Cycle: Standard bolt samples: 3-5 working days; non-standard bolts with structural design: 7-15 working days for prototyping; mass production lead time: 15-30 working days (depending on quantity).

Professional Technical Support: Our engineering team (with 15+ years of fastener experience) provides design optimization, such as material selection and weight reduction, to lower costs while ensuring performance.

Typical Application Fields

Automotive & Transportation: High-strength alloy bolts for engines, flange bolts for chassis, and corrosion-resistant stainless steel bolts for exhaust systems.
Aerospace & Aviation: Titanium alloy bolts for aircraft fuselages, high-temperature Inconel bolts for jet engines, and high-precision socket head cap screws for avionics.
Industrial Machinery: Large-diameter alloy steel bolts for wind turbine main shafts, stepped bolts for textile machinery, and hollow bolts for hydraulic systems.
Electronics & Electrical: Ultra-small stainless steel bolts for circuit boards, brass bolts for electrical enclosures, and anti-static bolts for semiconductor equipment.
Construction & Infrastructure: Hot-dip galvanized carbon steel bolts for bridges, corrosion-resistant bolts for marine engineering, and high-strength bolts for building steel structures.

1. Application scenario (e.g., automotive engine, wind turbine);

2. Key requirements (load capacity, corrosion resistance, temperature range);

3. Drawing/sample or standard number; 4. Quantity and delivery time.
