Manufactured from Class 10.9 high-strength steel, this M12 x 1.25mm fine thread hex tap bolt 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. The unthreaded shank section below the hex head carries shear loads through solid bolt body, improving fatigue performance under dynamic loading. With approximately 1,040 MPa tensile strength and a zinc plated finish for RoHS compliant corrosion protection, these tap bolts are specified for hydraulic systems, precision machinery, motorsport components, and instrumentation mounts demanding the highest combination of strength and thread security.
A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head
FT = Full Thread
PT = Partial Thread
