Class 8.8 Metric Hex Bolts are a medium strength, high tensile fastening solution available in coarse, fine and extra fine thread.
One of the most commonly used fasteners, our Class 8.8 hexagonal bolts include DIN 933/961 Full and DIN 931/960 Partial thread options.
Coarse and Fine Thread Diameter sizes are specified / written differently. Coarse thread bolt sizes are commonly noted without the pitch.
Example: M8X1.25 is a coarse thread pitch, commonly identified as M8. M8X1.0 is a fine thread pitch, identified as M8X1.0 Fine.
