Hammond 1591TS100BK Black #4 x 1/2" Self-Tapping Screws, 100-Pack

The 1591TS100BK is a 100-pack of black #4 x 1/2" self-tapping screws for Hammond plastic enclosures. It is the choice for builders who use black enclosures in the 1591 family and related series and want replacement screws that match the dark finish.

The hardware list classifies the part as assembly screws and names the 1591, 1591XX, 1551 and 1598 series as applicable. According to the long description, these are self tapping screws for plastic enclosures, in black.

The screws are steel and packed in shrink wrap. A pack contains 100 screws and has a shipping weight of 0.11 lbs (0.05 kg). The 1591TS100BK is RoHS compliant and REACH compliant, which supports equipment that must meet those material-restriction requirements.

The same #4 x 1/2" self-tapping screw is also listed without the black finish. In most cases, enclosures include all hardware needed for assembly, so this pack is for replacing lost or worn screws and for keeping spares on hand. Hardware packs may not be compatible with all parts in the listed series, so verify fit on the enclosure's replacement parts and accessories list before ordering.
