The SC611-50 is a package of 50 M3-0.5 x 25mm flat head screws. Unlike most M3 packs in the Small Case Hardware list, it is tied to a single family: the table lists it as the assembly screw for the RH-S series. Technicians, integrators and product builders who work with RH-S enclosures use it to replace lost screws or to keep a spare supply on the bench.

The manufacturer's long description is "FH M3-0.5 x 25", identifying a flat head screw with a metric M3 thread at 0.5mm pitch and a 25mm length. The RH-S series also appears against the 20mm version of this screw (SC610-50), so check which length your enclosure uses before ordering.

The package contains 50 screws. The SC611-50 is RoHS compliant and REACH compliant. For cataloguing and purchasing systems, it carries UPC 623980523903 and UNSPSC 39121301.

Enclosures in most cases include all hardware needed for assembly, so the SC611-50 is a replacement pack rather than a required add-on. 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.
