The 1590MS50BK is a 50-pack of black #6-32 x 1/2" replacement machine screws for Hammond's imperial 1590 series enclosures. It is a practical spare for anyone building or servicing 1590 or 1590K4 enclosures who needs matching black screws rather than mixed hardware.

The screws are steel with a black finish, and the short description identifies them as machine screws ("MACH SCREWS BLK 1X50"). The series hardware list classes them as assembly screws for the 1590 and 1590K4 series.

The part page lists an IP54 rating for this item. The 50 screws come in a bag with a shipping weight of 0.09 lbs (0.04 kg), a convenient quantity for repairs and small runs. The pack is RoHS compliant and REACH compliant.

If you prefer a larger quantity in the standard finish, note that the series hardware list also includes a 100-pack of #6-32 x 1/2" screws for the same series. In most cases enclosures include all hardware needed for assembly, and hardware packs may not be compatible with all parts in the listed series, so confirm fit on the enclosure's replacement parts and accessories list before ordering 1590MS50BK.
