Hammond SC576-50 M4 x 20mm Stainless Pan Head Screws, 50 Pack

The SC576-50 is a 50-pack of M4 x 20mm pan head screws in stainless steel. It covers more enclosure families than most packs in the Small Case Hardware list: it is listed as the assembly screw for the 1590Z, 1554, 1555, 1555F and 1557 series. That breadth makes it a sensible stock item for integrators, electrical contractors and maintenance departments who service several of these enclosure types.

The manufacturer describes the part as "M4 x 20 panhead screw - 50 pack" and the hardware list as "M4 x 20mm stainless steel screws". When ordering, the metric M4 thread and 20mm length are what to match against the screws originally supplied with your enclosure.

The 50 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 SC576-50 is sold for replacement 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.
