Engineered for high-stress industrial applications, the M12-1.75 x 50mm DIN 931 Hex Cap Screw offers an exceptional blend of tensile strength and reliability. Manufactured to rigorous Class 10.9 standards, this fastener is crafted from high-strength tempered alloy steel, providing a minimum tensile strength of 1040 MPa. This makes it an ideal choice for heavy-duty machinery, automotive repairs, and structural assemblies where safety and load-bearing capacity are paramount. This partially threaded bolt features a 50mm length and a standard 1.75mm coarse pitch, ensuring compatibility with a wide range of metric nuts and tapped holes. The DIN 931 specification indicates a smooth unthreaded shank under the head, which provides superior shear strength compared to fully threaded alternatives, making it perfect for joints where alignment and lateral stability are critical. To protect against the elements, each screw is finished with a durable zinc plating. This coating acts as a sacrificial barrier, offering excellent corrosion resistance and preventing rust in indoor or mildly damp environments. The classic hexagonal head design allows for maximum torque application using standard wrenches or socket tools, ensuring a secure, vibration-resistant fit every time. Whether you are performing professional-grade maintenance or tackling a robust DIY project, SKU 0154005 delivers the professional performance and structural integrity your work demands.
