Metric Hex Cap Screws, Class 8.8, Zinc Plated Steel, M10-1.25 x 120M PT
Diameter - Thread Pitch: M10-1.25
|
Manufactured from Class 8.8 steel, this M10 x 1.25mm fine thread hex cap screw combines precision thread engagement with the clamping force needed for general-purpose structural and mechanical joints. The fine pitch offers greater thread contact area and improved resistance to self-loosening compared to the standard M10 x 1.5mm coarse thread, making it the preferred choice in vibration-prone and precision-fit applications. 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 serve demanding roles in automotive drivetrain assemblies, hydraulic systems, and industrial machinery where vibration resistance and reliable clamping are essential.
A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head
FT = Full Thread
PT = Partial Thread
