Material/Finish

SNSU-AT
Main Body SUH660 (Equivalent to A286)

Application

Lighter-weight automobiles, aircrafts/aerospace equipment, robots, etc.
Semiconductor manufacturing equipment / gas turbines/steam turbines / coal-fired generating plants

Characteristics

  • SUH660 hex socket head cap screws.
  • SUH660 is heat-resistant austenitic steel equivalent to A286 (ASTM standards), which is mainly used in high-temperature environments.
  • The heat resistant temperature is 700°C. Retains high strength even in high temperature environments.
  • The strength per each screw is high, so smaller screw diameters and reduced quantities are available to save space and reduce weight.
  • For high-specific strength screws which can be made smaller and lighter-weight, see “What is specific strength?”.

Mechanical Properties

SUH660
Tensile Strength (N/mm2) 900 or Higher
0.2% Proof Load (N/mm2) 590 or Higher
Elongation (%) 15 or Higher

Mechanical properties are those with solution heat treatment + age hardening material.
Values in chart are for reference only. They are not guaranteed values.
Do not exceed the max. tightening torque.
Always carry out tests under performance conditions similar to actual conditions in advance in order to confirm safety.
