Strength Class A2 - 70

Characteristics

  • The head flange increases seating surface size, diffusing more pressure on the intended fastening material compared to conventional hex socket head bolts and helping prevent seating surface sinking. Also, the seating surface can be ensured even for large drilled holes.
  • Washer mounting work is not required, reducing the number of parts.
  • Ideal for screw fastening automation using robots, as washers are not used.
