The SC1550Z220-30 contains 30 M4 x 45mm flat head assembly screws in stainless steel, catalogued as replacement hardware for the 1550Z220 enclosure. It is aimed at technicians, maintenance teams and equipment builders who need the matching long fastener for that model when the original screws are lost or damaged.

Hammond's long description is "M4x45 flat head SS#304 for 1550Z220", identifying both the stainless steel grade (#304) and the enclosure it belongs to. The ordering table lists the applicable series as 1550Z and the hardware type as Assembly Screws.

The 30 screws are supplied in a plastic clamshell, with a listed shipping weight of 0.23 lbs (0.10 kg). The part is classed under Hardware with type Screws.

Most Hammond enclosures are delivered with all the hardware needed for assembly, so the SC1550Z220-30 is intended as a replacement or spares pack. Because hardware packs may not be compatible with every part in a listed series, confirm fit on the series landing page or in the "Replacement Parts and Accessories" section of the enclosure's part page.

The pack is RoHS compliant and REACH compliant, which simplifies material declarations for finished assemblies.
