M8 x 40mm Flat Point Socket Grub Screw | H4 Drive | Class 45H Steel BZP

The M8 x 40mm flat point socket grub screw is a compact headless fastener for shaft collar positioning. Its H4 socket, 1.25mm pitch and DIN 913 / ISO 4026 form make it suitable where a flush set screw needs to hold a component without projecting above the surface. As a flush grub screw, it is well suited to shaft collars, split collars and drive sleeves because it keeps round components seated without creating a raised fixing point.

Manufactured from Class 45H steel BZP, this DIN 913 grub screw suits dry environments where strong thread engagement and a practical plated finish are required. The combination of a flat point, metric thread and socket drive gives a controlled fixing for assemblies that need repeatable setting and removal. It gives a strong plated steel alternative where stainless steel is not required.

Common Applications

  • Shaft collars, split collars and drive sleeves using a M8 x 40mm flat point set screw
  • Access panel hardware and small mechanical linkages
  • OEM equipment builds using metric tapped holes
  • Machine guarding fixtures with limited clearance

Key Features and Benefits

  • Useful for locking shafts, collars and stops after alignment has been checked
  • Socket drive keeps the fixing accessible even where side clearance is limited
  • Flat point end type reduces localised marking compared with sharper set screw points
  • Available as part of a wider metric grub screw range for stocked maintenance spares
