The SC18609-50 is a package of 50 #8 x 3/8" self-tap assembly screws, listed as replacement hardware for the 516 series. It is intended for electricians, technicians and equipment builders who need to replace missing or worn fasteners on a 516 series enclosure.

The part page short description, "PKG-50 #8X3/8" PHIL TAP SCREW", identifies these as Phillips-drive tapping screws. The Small Case Hardware ordering table lists the description as #8 x 3/8" self-tap screws with a hardware type of Assembly Screws, and the applicable series as 516.

Each pack holds 50 screws and has a listed shipping weight of 0.05 lbs (0.02 kg), making the SC18609-50 a compact spares item for a service vehicle or workbench.

Hammond states that in most cases its enclosures include all hardware needed for assembly, so this pack is sold for replacement. 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 individual enclosure's part page to confirm the correct screw.

The SC18609-50 is listed as RoHS compliant and REACH compliant.
