This guide provides a detailed overview of China hex head shoulder bolts, covering their specifications, applications, materials, and considerations for selection and sourcing. We'll explore different types, sizes, and quality standards, helping you make informed decisions for your projects. Learn how to identify reliable suppliers and ensure you receive high-quality products.
A China hex head shoulder bolt is a type of fastener characterized by a hexagonal head and a cylindrical shoulder under the head. The shoulder provides a bearing surface and prevents the bolt from being pulled completely through the joined materials. This design is crucial in applications requiring precise positioning and controlled clamping force. They are widely used in various industries and are manufactured in China with varying grades of steel and finishes.
The key features of a China hex head shoulder bolt include its hexagonal head, cylindrical shoulder, threaded shaft, and overall length. Specifications such as thread size (e.g., M6, M8, M10), length, material grade (e.g., 3.6, 4.8, 8.8, 10.9), and surface finish (e.g., zinc-plated, black oxide) are crucial in selecting the appropriate bolt for a specific application. Understanding these specifications is vital to ensure proper fit and functionality.
China hex head shoulder bolts are typically made from various materials, most commonly carbon steel. Different grades of carbon steel offer varying levels of strength and corrosion resistance. Stainless steel is also a popular choice for applications requiring higher corrosion resistance. The choice of material greatly impacts the bolt's strength, durability, and cost.
While the basic design remains consistent, variations exist in China hex head shoulder bolts. These variations might involve different head styles (though the hexagonal head is most common), thread types, and surface treatments. Each variation is suited for different applications. For instance, a zinc-plated bolt might be preferred for outdoor use to increase corrosion resistance.
Sourcing high-quality China hex head shoulder bolts requires careful consideration. Look for suppliers with certifications like ISO 9001, indicating a commitment to quality management systems. Checking online reviews and testimonials can also help assess supplier reliability. Hebei Dewell Metal Products Co., LTD (https://www.deweLLfastener.com/) is one example of a company that provides a variety of fasteners.
Understanding the quality control measures implemented by the supplier is critical. Reputable suppliers will adhere to industry standards and perform rigorous testing to ensure consistent quality. Checking for compliance with international standards, such as those defined by ISO, is also essential. Inspecting a sample batch before placing a larger order is always recommended.

Note: Prices and lead times are illustrative examples and may vary depending on order quantity and other factors.
Selecting the right China hex head shoulder bolt requires a thorough understanding of its specifications, applications, and materials. By carefully considering these factors and choosing a reliable supplier, you can ensure the successful completion of your projects. Remember to prioritize quality and adhere to relevant industry standards for optimal performance and longevity.
