Grade 12.9 setscrews are high-strength fasteners commonly used in various mechanical and structural applications where robust holding strength is required.
These setscrews are often used in critical applications where failure could lead to safety hazards or operational issues. Common applications include automotive, aerospace, machinery, and construction industries.
The numerical designation "12.9" indicates the minimum tensile strength of the setscrew in megapascals (MPa). In this case, Grade 12.9 setscrews have a minimum tensile strength of 1200 MPa.
Size availability: M6, M8, M10, M12, M14, M16, M18, M20, M24.
Finish options: Zinc, Zinc Yellow and unplated self colour
