Description

Description

The high-tensile M8x40 button head socket screw, black, 10.9 represents a reliable fastener for demanding structural and engineering applications. Thanks to the high-strength class material, this screw withstands significant mechanical stress and guarantees an exceptionally strong joint.

This model features an M8 thread with a length of 40 mm and is supplied without additional surface treatment, which corresponds to the standard black finish for high-tensile screws. The button head contributes to a safe joint finish, as it significantly reduces the risk of clothing or surrounding objects catching on the edge.

Key Technical Parameters

  • Strength Class 10.9: Provides excellent tensile and shear resistance for stressed engineering assemblies.
  • DIN 7380-1 and ISO 7380 Standards: Guarantee maximum dimensional accuracy and trouble-free interchangeability during maintenance.
  • Hexagon Socket (key size 5): Allows precise and reliable transmission of tightening torque even in tight spaces.
  • Low-profile Head: A head height of only 4 mm helps to maintain the compact dimensions of your machinery.

During assembly, we recommend taking into account the absence of corrosion protection and ensuring adequate protection in case of outdoor or humid environments. To achieve maximum joint safety, always observe the recommended tightening torques for strength class 10.9.
