The SC618-50 is a package of 50 M4-0.7 x 20mm flat head screws. In the Small Case Hardware table it is the assembly screw listed for the RS2 and RZ enclosure series, making it the replacement pack for technicians and builders maintaining those enclosures.

The long description, "FH M4-0.7 x 20", specifies a flat head, a metric M4 thread at 0.7mm pitch and a 20mm length. Stating the thread pitch identifies this as a machine-thread screw, distinct from the M4 x 20mm self-tap screw with o-ring (SC624-50) that is also listed for the RS2 series. Check which type your enclosure uses before you order.

Each package holds 50 screws. The SC618-50 is RoHS compliant and REACH compliant, with UPC 623980523972 and UNSPSC 39121301 for procurement records.

Enclosures in most cases include all the hardware needed for assembly, so this package is intended for replacement or spares for OEM assemblers, integrators and service departments. Hardware packs may not be compatible with every part in a listed series, so check the series landing page or the "Replacement Parts and Accessories" section on your enclosure's part page before ordering.
