The 1593MS100BK is a 100-pack of black #4 x 5/8" self-tapping replacement screws for Hammond 1593 series enclosures. It is aimed at builders and service technicians who assemble black 1593 or 1599 enclosures and want the closing screws to match the dark enclosure colour.

The long description identifies the part as replacement screws for 1593 series enclosures, black, 100-pack. The series hardware list classifies them as assembly screws and names the 1593 and 1599 series as applicable. The short description confirms the 5/8" length.

The screws are steel and are packaged in shrink wrap. Each pack holds 100 screws with a shipping weight of 0.16 lbs (0.07 kg). The 1593MS100BK is RoHS compliant and REACH compliant, supporting equipment built to those material-restriction requirements.

The same #4 x 5/8" screw is listed without the black finish as well, and black #4 x 3/4" screws are listed for the 1593 and 1553 series. In most cases, enclosures include all hardware needed for assembly, so this pack is intended for replacements and spares. Hardware packs may not be compatible with all parts in the listed series, so check the enclosure's replacement parts and accessories list to confirm length and fit.
