The SC1550Z107-50 supplies 50 M4 x 25mm flat head assembly screws in stainless steel, listed by Hammond as replacement hardware for particular 1550Z enclosures. It is a practical spares item for maintenance departments and OEM builders working with these enclosures.

According to the long description, the screws are "M4x25 flat head SS#304 for 1550Z107-108", so the SC1550Z107-50 is tied directly to the 1550Z107 and 1550Z108 models. The Small Case Hardware ordering table lists the applicable series as 1550Z and 1590Z. Material is stainless steel, grade #304 per the description.

The screws are packed in a plastic clamshell, and the listed shipping weight is 0.23 lbs (0.10 kg). With 50 pieces per pack, one purchase can cover several enclosures or keep a service kit topped up.

Hammond enclosures typically ship with all the hardware needed for assembly; this pack is for replacement. Since hardware packs may not be compatible with every part in a listed series, verify the correct screw on the series landing page or the "Replacement Parts and Accessories" section of the enclosure's own part page before ordering.

The item falls under the Hardware category, type Screws, and is both RoHS and REACH compliant.
