- Cover screw for 1552 "D" size enclosures (1552D1, 1552D3, 1552D5)

The SC551BK-50 is a pack of 50 black #2 x 3/4" self-tapping cover screws for the "D" sizes of the 1552 hand-held ABS enclosure series: the 1552D1, 1552D3 and 1552D5. These are the screws that hold the two enclosure halves together, so the pack is useful for production builds, field service and for replacing screws lost during prototyping or rework.
On the 1552D enclosure drawings, SC551BK-50 is listed as the 1552D cover screw (Black). For reference, the series notes that black 1552 enclosures come with black screws and gray enclosures come with nickel plated screws. The natural-color version of this pack is SC551-50.
The part page lists the screw as "#2 X 3/4" FH SELFTAP BK-50 PCS" in its short description and "#2 X 3/4" PN SELFTAP BK" in its long description. The 1552D drawings give a recommended cover screw torque of 21-28 ozf-in (15-20 cN-m). Hammond's chemical resistance guidance advises against using Red Loctite or any thread locking compound on screws in its plastic enclosures.
The package measures 2.5 in x 1.5 in x 0.75 in (64 mm x 38 mm x 19 mm) and has a shipping weight of 0.07 lbs (0.03 kg). REACH and RoHS compliance are both listed as Yes.
