It indicates the high tensile strength of the steel, with 12.9 being one of the strongest grades available for standard socket head screws.
They are designed for mechanical use and may rust if exposed to extreme weather; stainless steel would be a better choice for marine or constant outdoor exposure.
You need a standard metric hex key (Allen key) that fits the specific diameter of the screw socket.
In non-critical applications, they can often be reused, but for high-stress structural joints, it is best practice to use new fasteners to ensure integrity.
Depending on the specific length (MPN), thread length may vary; please refer to the specific variant specifications for your project requirements.
Ensure the hex key is fully inserted into the socket and is not undersized or worn.
Check the thread pitch of both the screw and the hole; verify there is no debris or paint residue in the threads.
Proper installation is crucial for maintaining the integrity of these fasteners.
