Test piece: Socket Head Cap Screw M5x25(Stainless Steel)
Strength Classification: A2-70
·The numerical values listed above are for reference only.
The 0.2% permenant elongation of Strength Classification A2-70 is 450 MPa. When in use, be sure to use an axial force of less than 70% of the 0.2% permenant elongation.
Special surface treatment enables low coefficient of friction and prevents screw burnouts and biting. Please select appropriate surface treatment according to the usage condition.
Raydent* Treatment has extremely low spectral reflectivity and appropriate for use with optics machinery and tools that necessitate reflection prevention.
