Metric Hex Tap Bolt, Class 10.9 Zinc Plated Steel, M8 x 1.0 x 50M
Diameter - Thread Pitch: M8-1.0
|
This M8 x 1.0mm 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 M8 x 1.25mm 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.
DIN 930-933/ISO 4014-4017 compliant
A Hex Bolt is measured as: Diameter - Thread Pitch x Length from Under Head
FT = Full Thread
PT = Partial Thread
