The 1594TS100 is a 100-pack of #4 x 1" self-tapping replacement screws for Hammond 1594 series enclosures. It is for assemblers and maintenance technicians who need the long 1" self-tapping screws used to close 1594 enclosures, whether to replace lost hardware or keep a supply for production.

The short description reads "REPLACEMENT SCREWS #4X1"-ST", and the series hardware list describes the part as #4 x 1" self-tapping screws, classed as assembly screws. The 1594 series is the only applicable series listed for this pack.

Each pack contains 100 screws and has a shipping weight of 0.22 lbs (0.10 kg). The 1594TS100 is RoHS compliant and REACH compliant, which supports equipment that must meet those material-restriction requirements.

The hardware list also includes M3 x 18mm machine screws and M3-0.5 x 25mm watertight screws with o-rings that are listed for the 1594 series, so check which fastener style your enclosure uses. In most cases, enclosures include all hardware needed for assembly, so this pack covers replacements and spares. Hardware packs may not be compatible with all parts in the listed series; confirm on the enclosure's replacement parts and accessories list before ordering.
