Metric Hex Cap Screws, Class 8.8, Zinc Plated Steel, M10-1.25 x 40M FT

Diameter - Thread Pitch: M10-1.25
  • Hex head for standard wrench or socket installation
  • Class 8.8 medium-strength steel – approximately 800 MPa tensile strength
  • Known as a hex cap screw, hex bolt, or hex head bolt
  • Zinc plated finish – RoHS compliant corrosion protection
  • M10 x 1.25mm fine thread pitch – multiple lengths available

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

Product number: MHBZP88F1040
