Designed with a short, thin cup head per DIN7984 standards, this bolt balances compactness and stability, making it ideal for space-constrained assemblies.

Core Features & Benefits

12.9 Grade High-Strength Steel: Crafted from premium 12.9 grade alloy steel—one of the highest strength ratings for fasteners—offering exceptional tensile and shear strength. Suitable for heavy-load applications, machinery, and structural components that demand reliable durability.
DIN7984 Standard Compliance: Strictly adheres to DIN7984 specifications, ensuring uniform dimensions, thread precision, and compatibility with standard hex socket tools. The short, thin cup head design enables installation in tight spaces without compromising clamping force.
Black Oxide Finish: Features a corrosion-resistant black oxide coating that enhances wear resistance, prevents rust, and adds a sleek, industrial aesthetic. Ideal for both indoor and outdoor applications, even in moderate humidity.
Hex Socket Drive: Equipped with a hex socket (allen key) drive for efficient torque transfer, minimizing slippage and cam-out during installation. Ensures precise tightening, protects the fastener and workpiece, and simplifies operation in confined areas.
Multi-Size Versatility: Available in M5, M6, M8, M10, M12, and M16 sizes to accommodate diverse projects—from precision equipment and automotive parts to industrial machinery and structural fixtures.

Applications
