The SC1553C100BK is a package of 100 assembly screws listed as replacement hardware for the 1553 series. Its short description on the part page is "SC1553CBK - PKG OF 100 SCREWS", and it is aimed at repair technicians and OEM builders maintaining products housed in 1553 series enclosures.

In the Small Case Hardware ordering table, Hammond lists the SC1553C100BK as #4 x 1" self-tapping screws with a hardware type of Assembly Screws. Buyers comparing it with the SC1553C100 should note that the two packs are described differently in the hardware list, so confirm the screw your enclosure calls for.

The listed pack 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). One hundred screws per pack gives ample spares for service work.

Hammond enclosures normally include all the hardware needed for assembly; this item is for replacement. Because 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 your enclosure's part page before ordering.

The pack is RoHS compliant and REACH compliant.
