Grade 12.9 refers to the property class of the steel, indicating a high tensile strength of approximately 1200 MPa, making them suitable for heavy-duty mechanical use.
While they feature a bright zinc-plated finish for corrosion resistance, they are best suited for indoor or sheltered environments; heavy outdoor exposure may eventually lead to surface rust.
Yes, because they are manufactured from high-strength carbon steel, they will exhibit magnetic properties.
DIN 912 is a German standard that defines the dimensions and technical requirements for socket head cap screws with a metric thread.
If they have not been over-torqued or suffered visible deformation, they can generally be reused, but for critical safety applications, replacing them with new fasteners is recommended.
The socket is likely stripped or the hex key is worn; use a new hex key or a slightly larger high-quality bit to remove the screw.
Check for cross-threading or debris in the hole; back the screw out and clean the threads before re-inserting.
