The SC520-50 is a package of 50 M2.6 x 18mm self-tapping assembly screws. The Small Case Hardware list identifies them as the replacement assembly screws for the RH-S and RL enclosure series, making this pack useful for technicians and product builders who need to close up or rebuild one of those cases.

At 18mm long, these M2.6 screws are much longer than the M2.6 x 6mm PCB screws used inside the same families; they are classified as assembly screws, the fasteners that hold the enclosure itself together. Their self-tapping design cuts its own thread on installation, so no separate nut is needed.

Each package contains 50 screws and has a shipping weight of 0.05 lbs (0.02 kg). The SC520-50 is RoHS compliant and REACH compliant, and carries UPC 623980403168.

Because enclosures generally include all hardware needed for assembly, the SC520-50 serves as a replacement or spares pack. The manufacturer notes that hardware packs may not be compatible with all parts in a listed series, so confirm fit on the series landing page or in the "Replacement Parts and Accessories" section of your enclosure's part page before ordering.
