The SC526-50 is a pack of 50 #6 x 1/4" self-tapping Plastite screws with a pan head, made of steel with a zinc plate finish. The Small Case Hardware list assigns this part two roles in the 1556 and 1557 enclosure series: it is listed both as the PCB screw and as the panel screw. That makes it a practical single spares item for technicians and OEM assemblers who service either family.

Plastite is a self-tapping thread form, so the screws cut their own thread on installation without a separate nut. The short 1/4" length suits fastening boards and panels close to the mounting surface.

Each pack contains 50 screws. The package measures 2.5 in x 1.5 in x 0.75 in (64 mm x 38 mm x 19 mm) and has a shipping weight of 0.07 lbs (0.03 kg). The part is categorised as an accessory, type screws, and is RoHS compliant and REACH compliant.

In most cases enclosures include all hardware needed for assembly, so the SC526-50 is intended for replacement or spares. 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.
