Hammond 1551USB50BK #2 x 1/2" Black Self-Tapping Screws, 50-Pack

The 1551USB50BK is a replacement pack of 50 black #2 x 1/2" self-tapping assembly screws for Hammond's 1551MINI and 1551USB small plastic enclosure series. It is intended for technicians, product builders and maintenance teams who have lost, stripped or worn out the original screws that close these compact cases and need a matching set rather than generic hardware.

Each screw is made of steel with a black finish, so the replacement hardware keeps the dark appearance called out in the part description. The manufacturer lists the head as "FH-B" in the long description, and the screws are classed as assembly screws in the series hardware list, meaning they are the fasteners used to hold the enclosure halves together.

The pack contains 50 screws supplied in a bag, with a shipping weight of 0.06 lbs (0.03 kg). The part is RoHS compliant and REACH compliant, which helps when the enclosure is going into equipment that must meet those material-restriction requirements.

Keep in mind that, in most cases, Hammond enclosures ship with all the hardware needed for assembly; this pack is a reference replacement for when additional or spare screws are needed. Hardware packs may not be compatible with every part in the listed series, so confirm the fit against the enclosure's own replacement parts and accessories list before ordering 1551USB50BK.
