Hammond SC1553WC100BK M3-0.5 x 20mm Watertight Assembly Screws, 100 Pack

The SC1553WC100BK supplies 100 M3-0.5 x 20mm stainless steel screws, listed by Hammond as watertight assembly screws for the 1553W series. It is a replacement part for service technicians and OEM assemblers who maintain sealed 1553W enclosures.

The Small Case Hardware ordering table classes the item as Watertight Assembly Screws with the description "M3-0.5 x 20mm stainless steel screws", giving the metric diameter, the 0.5mm thread pitch and the 20mm length. On the part page, the short description reads "SC501SSLONGBK - PKG OF 100 SCR".

The pack is listed at 1.5 in x 2.5 in x 0.75 in (38 mm x 64 mm x 19 mm) with a shipping weight of 0.05 lbs (0.02 kg). One hundred screws per pack supports ongoing maintenance or a production batch of sealed enclosures.

In most cases Hammond enclosures include all hardware needed for assembly, so this pack is meant for replacements and spares. Hardware packs may not be compatible with every part in a listed series; check the series landing page or the "Replacement Parts and Accessories" section on the enclosure's part page to confirm whether your 1553W model takes the SC1553WC100BK or the shorter M3 x 18mm screw sold as SC1553WB100BK.

The SC1553WC100BK is RoHS compliant and REACH compliant.
