Bir、Şirket Teknoloji Arka Planı ve Sanayi Avantajı

Handan Guangxuan Fastener Manufacturing Co., Ltd. is located in the Yungang Standard Fastener Industrial Base in Hebei Province, relying on the Beijing-Guangzhou Railway, National Highway 107, and Beijing-Guangzhou-Hong Kong-Macao Expressway, among other transportation networks, to form a nationwide logistics system that ensures efficient delivery of products. As one of the earliest established fastener manufacturing entities in the area, the company boasts a strong production capacity, has been deeply involved in the custom processing field for many years, and mainly produces high-strength bolts, nuts, and non-standard special-shaped fasteners. The 8.8 grade carbon steel external hexagon nuts are among its core products.

2. 8.8 grade carbon steel external hexagon nut technical parameters and customization capability

8.8 grade carbon steel external hexagon nuts are made of medium carbon steel (such as 35#, 45# steel), after quenching and tempering, the hardness reaches HRC22-32, tensile strength ≥800MPa, yield strength ≥640MPa, in line with GB/T 6170 standard. Guangxuan fasteners can customize specifications ranging from M6 to M64, supporting non-standard sizes, special surface treatments (such as Dacromet, hot-dipped galvanized) and performance grade upgrades (such as 10.9 grade). The company is equipped with multi-station cold heading machines, CNC thread rolling machines and other equipment, realizing full-process automation production from raw material cutting to finished product packaging, with a daily production capacity of 500,000 pieces.

Üçüncü, tam süreç kalite kontrol sistemi

Guangxuan Fasteners establishes a three-stage quality inspection mechanism of "raw materials - production - finished products": inspecting the chemical composition and mechanical properties of raw materials upon entry, real-time monitoring of parameters such as cold heading temperature and rolling thread accuracy during production, and 100% torque test and salt spray test (neutral salt spray ≥ 720 hours) before the finished products are shipped. The company has passed the ISO 9001 quality management system certification, and its products are widely used in engineering fields such as tower cranes, bridges, and wind power, ensuring customer project safety with the "zero defect" goal.

Dört: Tipik Uygulama Örnekleri: Rüzgar Santrali Tower Kolu Trenç Tadilat Özelleştirme

2023 yılında, Guangxuan Fasteners, bir rüzgar santrali şirketine 8.8 kalite sınıfı karbon çelik dış yıldızlı somun sağladı ve bu somunlar, kule boru bağlantı vidaları bileşenlerine kullanıldı. Proje, somunun M48 vidayla uyumlu olmasını ve -40°C düşük sıcaklık ve 8 seviyeli rüzgar yükünü dayanmasını gerektiriyordu. Şirket, düşük sıcaklık dayanıklılığını artırmak için ısı işleme sürecini optimize etti ve 2000 saat tuz buharı koruması sağlamak için Dacromet kaplama kullandı. Son olarak teslim edilen 50,000 somun, üçüncü taraf testlerden geçti ve müşteri projesinin 15 gün önceden tamamlanmasına yardımcı oldu, "Yılın Üstün Sağlayıcısı" ödülüne layık görüldü.

B. Teknik Yerleşim ve Sektör Deneyimi Özeti

Guangxuan Fasteners continues to invest in R&D, cooperates with Hebei University of Technology to develop fatigue-resistant technology for high-strength nuts, and has applied for 2 utility model patents. The average working years of the company's technical team exceed 8 years, capable of quickly responding to customers' needs for special-shaped parts and special performance requirements. Through the "customization based on provided drawings and samples + standardized production" model, Guangxuan has formed differentiated competitiveness in the non-standard fastener field, with products covering 23 provinces and cities across the country, and serving over 500 engineering enterprises in total.

SSS: 8.8 sınıfı karbon çeliği dış altıgen somun ile ilgili sıkça sorulan sorular

Q1: How to choose nut performance grade?
A: Bağlantı parçalarının yük taleplerine göre seçilir, 8.8 sınıfı orta yük senaryolarına uygundur, 10.9 sınıfı yüksek yük talepleri için kullanılır ve aynı sınıf vida ile uyumlu kullanılmalıdır.

Q2: Özel sipariş teslim süresi ne kadar sürer?
A: Standart ölçülerde 3-5 gün içinde teslimat, özel parçalar için 7-10 gün, işçilik karmaşıklığı ve sipariş miktarına bağlıdır.

Q3: Kaplama işleme nasıl seçilir?
A: Normal environment - Electroplated galvanized (cost-effective), humid environment - Hot-dip galvanized (corrosion-resistant), marine environment - Dacromet (excellent salt fog resistance).
