The 1421J6 is a small replacement pack of six #6-32 x 1/4 assembly screws. It is listed in the manufacturer's small case hardware reference for thirteen series: 1401, 1411, 1412, 1415, 1426, 1431, 1434, 1441, 1444, 1451, 1452, 1454 and 1456. Its short description on the part page reads "Self-Tapping Screws 6 Pack".

This pack is intended for technicians, repair benches and OEM builders who have lost or damaged the original fasteners and need a like-for-like replacement rather than a full bulk box. With six screws per pack, it is sized for replacing the assembly screws on an individual unit.

As the manufacturer notes, in most cases enclosures include all hardware needed for assembly, so this pack is a spare-parts item. Hardware packs may not be compatible with every part in the listed series; the manufacturer recommends checking the series landing page or the "Replacement Parts and Accessories" list on the specific enclosure's part page before ordering.

The 1421J6 is classed under hardware, type screws. It is RoHS and REACH compliant and has a shipping weight of 0.01 lbs (0.00 kg). If you need a black finish, the matching black pack is 1421J6BK, and an 8-screw version of the same #6-32 x 1/4 description is 1421J8.
