M2.5 x 4mm Flat Point Socket Grub Screw | H1.3 Drive | A4 Stainless Steel

For textile machinery, the M2.5 x 4mm flat tip grub screw provides positive location without the space taken by a traditional headed bolt. Its H1.3 internal socket allows access through a small clearance point during installation or servicing. Engineers often select this metric grub screw when keeps rotating equipment settings stable during routine use in rollers, hubs and alignment collars.

The A4 stainless grade is suited to demanding corrosion-resistant assemblies where long-term reliability matters more than the lowest component cost. Because the screw is headless, it can be recessed into a threaded component to reduce snagging and keep the surrounding assembly clear. It is a good option for buyers comparing corrosion-resistant grub screws for harsher service conditions.

Common Applications

  • Rollers, hubs and alignment collars using a M2.5 x 4mm 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
