The 1594WMS100 is a 100-pack of watertight M3-0.5 x 25mm stainless steel screws with o-rings for Hammond 1594 series enclosures. It is intended for engineers and integrators who seal 1594 enclosures and need replacement fasteners that include the o-ring at each screw point.

The series hardware list classifies the part as watertight assembly screws and describes it as M3-0.5 x 25mm stainless steel screws with o-ring. The 1594 series is the applicable series listed. The manufacturer's short description is "REPLACEMENT SCREWS 100/PKG".

Each pack contains 100 screws with a shipping weight of 0.27 lbs (0.12 kg). The 1594WMS100 is RoHS compliant and REACH compliant, supporting equipment that must meet those material-restriction requirements.

For 1594 enclosures that do not use the watertight fastening, the hardware list also includes M3 x 18mm screws and #4 x 1" self-tapping screws for the series. In most cases, enclosures include all hardware needed for assembly, so this pack is intended for replacements and spares. Hardware packs may not be compatible with all parts in the listed series; check the enclosure's replacement parts and accessories list to confirm that the watertight screw is the right choice.
