The SC570-20 is a 20-pack of M6 x 30mm stainless steel pan head screws. The Small Case Hardware list identifies it as the assembly screw for the 1590ZGRP and 1590ZGRPBK enclosure series, making it the replacement pack for technicians and installers maintaining either version of that enclosure.

The manufacturer describes the part as "M6 X 30MM SS PN SCREW": metric M6 thread, 30mm length, pan head, and stainless steel as the specified material. With 20 pieces per pack, it holds more screws than the 12-packs offered for other M6 lengths in the range.

The 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 0.24 lbs (0.11 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 SC570-20 is intended for replacements and 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.
