| High Light | M10 M16 carbon steel bolt ，Gr12.9 zinc plated stud bolt ，HDG stud metal bolt with nut | ||
This series of heavy-duty stud bolts is engineered for the most demanding industrial fastening applications, combining the highest carbon steel strength class with a selection of robust corrosion-protective finishes. Manufactured from premium alloy steel and heat-treated to achieve the Grade 12.9 property class, these M10 and M16 studs offer a minimum tensile strength of 1200 MPa, making them suitable for extreme loads and high-stress environments. They are available with a comprehensive range of zinc-based finishes to suit various environmental exposures: Blue Zinc, White Zinc, Yellow Zinc Plated, standard Galvanized, and Hot Dip Galvanized (HDG). Designed to conform to DIN938 (stud bolts with double-end), these studs are paired with a matching heavy-duty hex nut (Grade to suit application), providing a complete, high-strength fastening system ready for critical connections in construction, infrastructure, and heavy machinery.
| Industry | Usage |
|---|---|
| Automotive | High-strength applications in engines, heavy-duty machinery, and bridge construction |
| Mechanical | Connecting mechanical parts, circuit boards, engines, transmissions in various industries |
| Energy | Connecting power generation equipment and transmission lines |
| Architectural | Building structures, shipbuilding, and petrochemical equipment |
These Gr12.9 stud bolts with heavy-duty nuts are the preferred choice for structural steel connections, heavy equipment assembly, infrastructure projects, and industrial plant installations.
M10 Size: Commonly used in medium-duty structural connections, machinery guards, and equipment mounting points where high strength is required in a compact form factor.
M16 Size: A standard size for primary structural connections in steel buildings, bridges, and heavy machinery frames, capable of transmitting very high loads.
The selection of finish is critical to application longevity:
Blue/White/Yellow Zinc Plated: Suitable for general industrial and indoor applications with moderate humidity.
Galvanized (Standard): Provides a thicker zinc coating for improved outdoor durability.
Hot Dip Galvanized (HDG): The ultimate choice for the most severe outdoor exposures, such as transmission towers, marine structures, highway signage, and wastewater treatment plants, offering decades of corrosion protection.
The included heavy-duty nut is selected to match the strength of the stud, ensuring the entire assembly can achieve its full load potential.
The primary advantage is the Grade 12.9 strength rating, delivering the ultimate load-bearing capacity available in carbon steel fasteners, essential for safety-critical connections. The extensive range of finishes—from standard zinc plating to heavy-duty HDG—allows engineers to precisely specify the level of corrosion protection needed, matching the fastener's durability to the environment and avoiding premature failure. Conformance to DIN938 ensures dimensional accuracy, proper thread run-out, and interchangeability. The inclusion of a matching heavy-duty nut guarantees that the entire fastening system can achieve the design preload and withstand the intended service loads. The availability of both M10 and M16 sizes covers a wide spectrum of common industrial and structural bolting requirements.
