This guide is for engineers, tradespeople, and DIY enthusiasts needing a strong, reliable fastening solution. The Forgefix M12 x 40mm High Tensile Set Screw provides exceptional strength and corrosion resistance for demanding applications, though correct torque and material matching are crucial for optimal performance.
High Tensile Strength: Made from Grade 8.8 steel for superior load-bearing capacity and durability in critical applications.
Corrosion Resistance: Zinc plating (ZP) offers enhanced protection against rust and environmental wear, extending the lifespan of the fastener.
Fully Threaded Design: Ensures maximum engagement with mating components, providing a secure and consistent hold along the entire screw length.
DIN 933 Compliant: Manufactured to international standards, guaranteeing dimensional accuracy, quality, and interchangeability.
Versatile Application: Suitable for a wide range of engineering tasks, including fastening various materials or securing into pre-tapped holes.
Sacrificial Anode Protection: The zinc coating actively protects the underlying steel, even if the barrier is scratched, by sacrificing itself to prevent oxidation.
Excellent strength for heavy-duty applications.
Good corrosion resistance due to zinc plating.
Fully threaded for maximum grip.
Standardized for compatibility (DIN 933).
Versatile for various materials and engineering uses.
Requires appropriate tools and torque control to prevent damage.
Not suitable for extremely high-temperature environments where zinc plating might degrade.
Zinc plating can be damaged by harsh chemicals or abrasion, reducing corrosion protection.

The Forgefix M12 x 40mm High Tensile Set Screw is engineered for robust performance in challenging environments. Its Grade 8.8 steel construction means it can withstand significant shear and tensile forces, making it ideal for structural connections, heavy machinery assembly, and automotive applications where fastener failure is not an option. The zinc plating provides a crucial layer of defense against rust and oxidation, particularly valuable in outdoor or humid conditions. For example, in building an outdoor steel frame, these screws would resist weather-induced corrosion far better than unplated alternatives. The fully threaded design ensures a strong, continuous grip, whether securing two components together with a nut or driving into a pre-tapped hole in a thick metal plate. Adherence to DIN 933 standards means consistent quality and predictable performance in critical engineering tasks.
Ensure the receiving hole or nut thread matches the M12 screw diameter.
Use appropriate wrenches or sockets for the screw head to ensure a secure fit and prevent damage during tightening.
Apply correct torque settings according to application specifications to avoid over-tightening or under-tightening.
Always use a compatible washer to distribute the load and protect the material surface.
Nuts: Compatible with M12 nuts of various types (e.g., hex nuts, lock nuts), preferably those matching or exceeding the screw's tensile strength (e.g., Grade 8).
Washers: Use with M12 washers, including plain, spring, or lock washers, depending on application needs for load distribution or vibration resistance.
Materials: Suitable for fastening metal, wood (with appropriate pre-drilling and inserts), and other dense materials.
Store in a dry environment to prevent premature corrosion of the zinc plating.
Avoid abrasive cleaning methods or harsh chemicals that could damage the zinc coating.
Inspect screws for damage or corrosion before use, especially if reusing them.
