These are Grade 12.9 screws, which indicate a high tensile strength of approximately 1,200 MPa.
No, they are made from high-strength alloy steel with a zinc plating for improved corrosion resistance.
While the zinc plating offers some protection, they are not recommended for constant exposure to water or outdoor weather without further sealing.
DIN 912 is a German industrial standard defining the dimensions and specifications for socket head cap screws.
Yes, their high tensile strength makes them suitable for many automotive applications, provided the dimensions and grade meet the manufacturer's requirements.
Ensure you are using the correct metric hex key size and that it is fully seated in the bolt head before applying torque.
Verify the thread pitch is correct and clear any debris or metal filings from the mounting hole before attempting to screw again.
For proper setup, ensure the pilot hole or threaded insert is exactly M10. Use a high-quality Allen key to avoid stripping the socket interior. To maintain the life of the finish, store the screws in a dry, low-humidity environment. If used in a corrosive environment, consider adding a light coat of anti-seize lubricant, which also prevents thread galling during frequent disassembly.
