The 1555TS100 is a 100-pack of #4 x 1/4" self-tapping panel screws for the Hammond 1555F enclosure series. It is aimed at builders and service technicians who need to replace or stock the screws that fasten panels on 1555F enclosures, whether for a single repair or a production run.

The manufacturer describes the screw as "#4 X 1/4 TYPE 25 PAN PHIL", which identifies a Type 25 screw with a pan head and Phillips drive. The material is listed as stainless steel.

The series hardware list classifies these fasteners as panel screws and gives 1555F as the applicable series. The pack contains 100 screws and has a shipping weight of 0.1 lbs (0.05 kg).

This part is RoHS compliant and REACH compliant, which supports builds that must meet those material-restriction requirements. As the hardware reference notes, in most cases enclosures include all hardware needed for assembly, so the 1555TS100 is intended as replacement or spare stock. Hardware packs may not be compatible with all parts in the listed series; check the 1555F enclosure's replacement parts and accessories list to confirm the match.
