Metric Hex Cap Screws, Class 8.8, Zinc Plated Steel, M12-1.25 x 60M FT
Diameter - Thread Pitch: M12-1.25
|
Manufactured from Class 8.8 steel, this M12 x 1.25mm fine thread hex cap screw provides maximum thread engagement for applications requiring precise tensioning and superior vibration resistance. The 1.25mm pitch is finer than both the standard M12 coarse (1.75mm) and standard fine (1.5mm) threads, offering the tightest helix angle available in this diameter for critical assemblies where loosening cannot be tolerated. Class 8.8 delivers approximately 800 MPa tensile strength and serves as the metric equivalent to SAE Grade 5. Available in both partial and full thread configurations, these hex cap screws with a zinc plated RoHS compliant finish are specified for hydraulic systems, precision machinery, motorsport components, and instrumentation mounts demanding reliable strength and thread security.
A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head
FT = Full Thread
PT = Partial Thread
