(double end stud bolt manufacturers)
The global demand for double end stud bolts has surged by 18% since 2020, driven by expanding construction, energy, and automotive sectors. As critical fastening components, these bolts require precision engineering to meet ISO 898-1 and ASME B18.31 standards. Leading double end stud bolt manufacturers
leverage advanced CNC machining and hot-forging techniques to ensure tensile strengths ranging from 800 MPa to 1,200 MPa, catering to high-stress environments such as pipeline systems and heavy machinery.
Modern manufacturers employ automated threading systems with tolerances of ±0.01 mm, reducing material waste by 22% compared to traditional methods. Heat treatment protocols, including quenching and tempering, enhance hardness (HRC 34–40) while maintaining ductility. Electroplating or hot-dip galvanizing (minimum 80 µm coating) ensures corrosion resistance in marine or chemical applications, extending service life by 15–20 years.
Manufacturer | Product Range | Material Grade | Price (USD/unit) | Lead Time |
---|---|---|---|---|
China Double End Stud Bolt Co. | M12–M64 | ASTM A193 B7 | $2.50–$18.00 | 14 days |
EuroFasten GmbH | M8–M48 | EN 14399-6 | $4.20–$25.00 | 21 days |
US Bolt Masters | M10–M56 | SAE J429 | $3.80–$22.50 | 18 days |
Wholesale double end stud bolt manufacturers offer tailored specifications, including non-standard lengths (up to 3,000 mm), left-hand threading, and alloy steel variants (e.g., AISI 4140/4340). Custom coatings like Xylan or Dacromet provide friction coefficients below 0.12, ideal for aerospace or renewable energy projects. Batch orders exceeding 10,000 units often qualify for volume discounts up to 30%.
Quality assurance involves 100% magnetic particle inspection (MPI) and ultrasonic testing to detect microfractures. Leading suppliers maintain traceability through QR-coded packaging, aligning with API 20E and DNV-GL certifications. Fatigue resistance testing under 2 million cycles at 75% yield strength ensures reliability in dynamic loading scenarios.
Industry | Use Case | Bolt Specifications | Performance Gain |
