Metric Hex Cap Screws, Class 8.8, Zinc Plated Steel, M12-1.5 x 55M PT
Diameter - Thread Pitch: M12-1.5
|
This M12 x 1.5mm fine thread hex cap screw is manufactured from Class 8.8 steel with a zinc plated finish for corrosion protection in general industrial environments. The fine thread pitch provides a tighter helix angle than the standard M12 x 1.75mm coarse thread, resulting in higher tensile strength per bolt, greater resistance to vibrational loosening, and finer adjustment capability during installation. Class 8.8 steel delivers approximately 800 MPa tensile strength, making it the standard metric grade for general-purpose structural and mechanical connections. Available in both partial and full thread configurations, these fine pitch hex cap screws serve applications in precision machinery, automotive assemblies, and vibration-sensitive equipment where thread security and accurate clamping control are critical.
A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head
FT = Full Thread
PT = Partial Thread
