The SC1553C100 is a package of 100 M3-0.5 x 20mm stainless steel assembly screws, listed as replacement hardware for the 1553 series. It is intended for technicians, product developers and OEM assemblers who need metric machine-thread fasteners for 1553 series enclosures.

Hammond's short description reads "SC1553C - PKG OF 100 SCREWS", and the Small Case Hardware ordering table specifies the contents as M3-0.5 x 20mm stainless steel screws, hardware type Assembly Screws. The M3-0.5 callout gives both the metric diameter and the 0.5mm thread pitch.

The pack's listed size is 1.5 in x 2.5 in x 0.75 in (38 mm x 64 mm x 19 mm) and its shipping weight is 0.05 lbs (0.02 kg). With 100 screws included, the SC1553C100 covers repeated servicing or a batch of builds.

In most cases Hammond enclosures ship with all the hardware needed for assembly, so this pack is sold for replacement and spares. Hardware packs may not be compatible with every part in the listed series, so Hammond recommends checking the series landing page or the "Replacement Parts and Accessories" section on the enclosure's part page before ordering.

The SC1553C100 is listed as RoHS compliant and REACH compliant.
