Metric Hex Tap Bolt, Class 10.9, Zinc Plated Steel, M16 x 1.5 x 60M
Diameter - Thread Pitch: M16-1.5
|
This M16 x 1.5mm fine thread hex tap bolt is manufactured from Class 10.9 high-strength steel with a zinc plated finish for corrosion protection in general industrial environments. The fine thread pitch provides a tighter helix angle than the standard M16 x 2.0mm coarse thread, resulting in higher tensile strength per bolt, greater resistance to vibrational loosening, and finer adjustment capability during installation. Class 10.9 steel delivers approximately 1,040 MPa tensile strength, making these fine thread tap bolts ideal for precision machinery, automotive engine assemblies, aerospace support structures, and vibration-sensitive equipment where both strength and thread security are critical.
A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head
FT = Full Thread
PT = Partial Thread
