The SC527-50 is a package of 50 replacement screws, described by the manufacturer as "#6 x 1/2" PN PLAS TAP": a #6 x 1/2" pan head Plastite self-tapping screw. The Small Case Hardware list identifies it as the assembly screw for the 1556 series, so it is the pack to reach for when a 1556 case has lost its closing screws or needs a set of spares for field service.

At 1/2" long, the SC527-50 is twice the length of the #6 x 1/4" screws used for boards and panels in the same series, reflecting its job of holding the enclosure together. The self-tapping Plastite thread forms its own thread as it is driven.

The pack ships in a bag; the package measures 2.5 in x 1.5 in x 0.75 in (64 mm x 38 mm x 19 mm) with a shipping weight of 0.05 lbs (0.02 kg). The part page lists the material as ABS Plastic and places the part in the accessories category. It is RoHS compliant and REACH compliant.

Enclosures in most cases include all hardware needed for assembly, so the SC527-50 is intended for replacement. Hardware packs may not be compatible with every part in a listed series, so check the series landing page or the "Replacement Parts and Accessories" section on your enclosure's part page before ordering.
