I. Company Profile: Professional Fastener Production Strength

Handan Guangxuan Fastener Manufacturing Co., Ltd. is located in Yongnian, Hebei——a renowned domestic base for standard fastener industry. Relying on the Beijing-Guangzhou Railway, National Highway 107, Beijing-Guangzhou-Hong Kong-Macau Expressway, Qinghong Expressway, and other three-dimensional transportation networks, it achieves efficient nationwide logistics coverage. As one of the earlier-established manufacturing entities in the area, the company specializes in custom processing of fasteners, mainly producing tower crane bolts, high-strength bolts, double-end bolts, high-strength nuts, and other standard fasteners. It also undertakes custom services for non-standard and special-shaped fasteners according to customer drawings and samples, meeting diverse industrial requirements.

Section 2: Product Advantages: Customized 8.8 Grade Carbon Steel Hex Nuts

The company specializes in the research and development of high-strength fasteners. The 8.8-grade carbon steel external hexagon nuts are made of high-quality carbon steel material, enhanced with heat treatment technology to improve tensile strength and corrosion resistance, meeting industry standards such as GB/T 3098.1. Product specifications range from M6 to M48, supporting customization of parameters such as length and thread accuracy. Complementary components such as trapezoidal screw threads and pin shafts are available, providing a one-stop procurement solution. The factory is equipped with automated production equipment and a full-process quality inspection system, implementing 12 inspection procedures from raw material entry to finished product delivery to ensure product dimensional accuracy ±0.01mm and surface hardness HRC28-32, meeting stringent requirements of fields such as mechanical manufacturing and construction engineering.

Section 3: Service Features: Full-process Standardized Management

Guangxuan Fasteners establishes a "customer-centric" service mechanism, offering full-cycle tracking from communication of requirements, design of drawings, to production and delivery. For customized projects, a technical team led by engineers with over 10 years of experience is assembled, completing scheme optimization and quotation feedback within 72 hours. The logistics process leverages the location advantage of the Yongnian Industrial Base, establishes long-term cooperation with multiple logistics companies, ensuring delivery to major cities across the country within 48 hours, and provides real-time logistics information inquiry service.

Four, Cooperation Cases: Industry Practice Validates Quality

A large-scale machinery manufacturing enterprise once customized a batch of M36×150mm 8.8-grade carbon steel external hexagonal nuts for critical connections in lifting equipment. The Guangxuan team, based on the customer-provided load parameters, optimized the thread angle and chamfer design of the nuts, enhancing the fatigue resistance by 20%. The project took only 15 days from design confirmation to delivery, and after 3 months of continuous operation testing, achieved a zero failure rate, earning high recognition from the customer and subsequently reaching a long-term cooperative agreement.

Five, Business Philosophy: Quality-oriented, Service-driven

The company always adheres to the tenet of "surviving through quality, developing through credibility, and seeking benefits through service." All products strictly comply with industry standards and customer-specific requirements. Through the ISO9001 quality management system certification, we establish archives of raw material traceability, production records, and finished product samples to ensure traceability of every batch. A comprehensive after-sales team provides 24-hour technical consultation and return/exchange services, with customer satisfaction reaching over 98% for three consecutive years. Our products are sold in more than 30 provinces and municipalities across the country, making us a trusted partner for many industrial enterprises.
