Heatsink part numbers for hailo 8 M.2 module and Raspeberry AI HAT+?

Does anyone have a brand/part number for

  • a heatsink that fits the Hailo 8 M.2
  • a heatsink that fits the Raspeberry AI HAT+
    Those two products have different holes on the PCB, for fixing a heatsink
    I was not able to find any product available from the usual electronic supplier (Mouser, Digikey, RS components, Farnell etc.)
