The SC1553A100 is a package of 100 #4 x 1/2" self-tap assembly screws listed as replacement hardware for the 1553 series. It is a spares item for product designers, repair technicians and OEM assemblers who build or service equipment housed in 1553 series enclosures.

Hammond describes the part as "SC1553A - PKG OF 100 SCREWS", and the Small Case Hardware ordering table specifies the screw as #4 x 1/2" self-tap with a hardware type of Assembly Screws.

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 the shipping weight is 0.05 lbs (0.02 kg). With 100 screws per pack, the SC1553A100 suits small production runs and keeps a service bench stocked.

Hammond notes that in most cases its enclosures include all hardware needed for assembly, so this pack is meant for replacement. Hardware packs may not be compatible with every part in the listed series; check the series landing page or the "Replacement Parts and Accessories" section on the enclosure part page to confirm. A black version is offered separately as SC1553A100BK.

The pack is RoHS compliant and REACH compliant.
