*Minimum Tensile Strength: 1220N/mm2
Shear Strength: 624N/mm2
Minimum Elongation: 8%
Working Temperature:
-50°C + 300°C
Minimum Hardness:
Rockwell 38 HRC

Hardness
To test that the hardness is in accordance with the values specified: Socket shoulder screws
The test shall be made on the point after 0.38mm has been removed by grinding.
*Where tensile tests cannot be carried out because sizes are too small, the hardness test is acceptable.
**It is recommended that tightening torque be limited to these values when screws are to be tightened or loosened with standard keys or bits.
