Engineering and Customization
Our in-house R&D team works closely with customers to develop fasteners from drawings or samples. We produce to international standards including GB, DIN, ANSI, and BS, and we specialize in non-standard parts that don't fit standard categories. Whether it's a unique head shape, a special thread pitch, or a specific material requirement, we can engineer a solution that meets your performance and assembly needs.
We also provide value engineering support, helping you select the right material and coating for your environment—whether that means corrosion resistance for marine use, conductivity for electrical applications, or weight reduction for aerospace.
Quality Assurance and Testing
Quality is built into every step of our process. We passed ISO9001:2000 quality management certification in 2017 and maintain our own laboratory with advanced inspection equipment. Our factory uses optical sorting technology to ensure every batch meets dimensional and surface requirements. We also operate a quenching furnace for heat treatment, ensuring the mechanical properties of our fasteners meet specified strength grades.
For critical applications, we can provide material certificates, test reports, and traceability documentation. Our quality system is designed to give you confidence in every shipment.
Production Capacity and Lead Times
With over 100 sets of machines and a production capacity of 8,000 tons per year, we can handle both small prototype runs and large-volume orders. Our cold heading workshop and supporting mold workshop allow us to produce complex geometries efficiently. We also have intelligent packaging lines to ensure your fasteners arrive in perfect condition.
Typical lead times depend on the complexity and quantity of the order, but we work with you to schedule production that aligns with your project timeline.
Information We Use to Configure Your Solution
To prepare an accurate quotation and production plan, we need the following details from you:
- Detailed drawings or samples (including dimensions, tolerances, and thread specifications)
- Material grade and any special material requirements
- Quantity and packaging preferences
- Surface treatment or coating requirements (e.g., zinc plating, passivation, anodizing)
- Applicable standards (DIN, GB, ANSI, BS) or custom specifications
- Target application and environmental conditions (for material selection)
With this information, our engineering team can confirm feasibility, suggest optimizations, and provide a detailed proposal.
Global Shipping and Support
We export to Europe, Australia, Africa, the United States, and other regions. Our team handles export documentation and ensures compliance with international regulations. We provide after-sales support to address any issues that may arise during installation or use.
Frequently Asked Questions
Q: Can you produce fasteners that are not covered by standard specifications?
A: Yes, we specialize in non-standard fasteners. Send us your drawings or samples, and we will develop a custom solution tailored to your application.
Q: What materials do you support for custom fasteners?
A: We work with carbon steel, stainless steel (304, 316), aluminum, brass, copper, and titanium alloys (e.g., Grade 5). We can also source other materials based on your requirements.
Q: Do you provide certificates for your products?
A: Yes, we can provide material certificates, test reports, and ISO9001 quality system certificates upon request.
Q: What is your minimum order quantity?
A: MOQ varies by product type and complexity. For standard items, we can accommodate small orders; for custom parts, we typically require a minimum quantity to justify tooling costs.
Q: How do you ensure quality before shipment?
A: We conduct in-process inspections and final quality checks using our laboratory and optical sorting equipment. We can also arrange third-party inspections if required.
