The SC574-30 is a 30-pack of M4 x 30mm stainless steel screws, listed in the Small Case Hardware table as assembly screws for the 1590Z series. It gives maintenance crews, electricians and OEM builders a straightforward way to replace missing M4 fasteners on a 1590Z enclosure or to keep spares for installation work.

The manufacturer's description reads "M4 X 30MM SS SCREW": metric M4 thread, 30mm long, with stainless steel specified as the material. The 1590Z family uses both M4 and M6 screws in various lengths, so confirm the thread and length your enclosure requires.

The 30 screws are supplied in a plastic clamshell measuring 2.5 in x 1.5 in x 0.75 in (64 mm x 38 mm x 19 mm), with a shipping weight of 0.18 lbs (0.08 kg). The part is categorised as hardware, type screws, and is RoHS compliant and REACH compliant.

Enclosures in most cases include all hardware needed for assembly, so the SC574-30 is for replacement or spares. 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.
