Metric Hex Tap Bolt, Class 10.9, Zinc Plated Steel, M10 x 1.25 x 65M

Diameter - Thread Pitch: M10-1.25

Hex head for standard wrench or socket installation
Class 10.9 high-strength steel – approximately 1,040 MPa tensile strength
Known as a hex cap screw or tap bolt, these are fully threaded
Zinc plated finish – RoHS compliant corrosion protection
M10 x 1.25mm fine thread pitch – multiple lengths available

Manufactured from Class 10.9 high-strength steel, this M10 x 1.25mm fine thread hex tap bolt combines precision thread engagement with the clamping force required for high-performance 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. With approximately 1,040 MPa tensile strength and a zinc plated finish for RoHS compliant corrosion protection, these tap bolts serve demanding roles in automotive drivetrain assemblies, hydraulic systems, and heavy industrial machinery.

A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head
FT = Full Thread
PT = Partial Thread

Product number: MHBZP109F1065
