Frequently Asked Questions
DIN 912 and ISO 4762 are largely equivalent standards for socket head cap screws. ISO 4762 is the international harmonization of the German DIN standard, ensuring the products are interchangeable globally.
Class 12.9 provides significantly higher tensile and yield strength, which is critical for machinery and tools that experience extreme torque and repetitive stress, preventing deformation and failure.
Yes, while we offer standard metric coarse threads, we specialize in customizable fine thread options to meet the specific precision requirements of your technical drawings.
Our screws are made from high-quality alloy steel (SCM435/40Cr). Depending on the environment, we can provide various coatings such as zinc plating or oil-quenching to enhance corrosion resistance.
Absolutely. The high precision and vibration resistance of our DIN 912 screws make them ideal for medical frames, such as CT scanners, where stability and reliability are paramount.
All batches undergo rigorous hardness testing (controlled per EN ISO 898-1) to ensure they meet the specified 39-44 HRC range, accompanied by visual verification and certification papers.
