The SC1550Z116-30 is a 30-piece pack of M4 x 30mm stainless steel flat head assembly screws, offered as replacement hardware for selected 1550Z enclosures. It is intended for technicians, panel builders and OEM teams who need the correct long lid screw for these models.

Hammond's long description reads "M4x30 flat head SS#304 for 1550Z116-117-137-139", which identifies the 1550Z116, 1550Z117, 1550Z137 and 1550Z139 as the target enclosures. The ordering table lists the applicable series as 1550Z. Material is stainless steel, #304 grade according to the description.

Unlike the 50-piece packs in the same hardware family, this part contains 30 screws. It ships in a plastic clamshell with a listed shipping weight of 0.18 lbs (0.08 kg), and is catalogued under Hardware with type Screws.

Hammond enclosures usually come with all the hardware needed for assembly, so the SC1550Z116-30 is for replacement or spares. Hardware packs may not be compatible with every part in a listed series; Hammond recommends checking the series landing page or the "Replacement Parts and Accessories" section on the enclosure's part page to confirm the right screw.

The pack is listed as RoHS compliant and REACH compliant.
