Powr-Flite Black Serrated H...

Product details
This is a black-finished Hi-Lo screw, part number A732-8414, sized No. 8 by 7/16 in. with a serrated pan head. Its black finish blends in against dark plastic housings, the serrated underside of the head resists backing out under vibration, and the Hi-Lo thread pattern is designed to bite into plastic bosses rather than pre-tapped metal. A Hi-Lo thread alternates a tall, sharp crest with a shorter one, which is what lets it hold in a moulded boss without cutting away the plastic the way a machine-screw thread would.
Keeping a small stock of these on hand pays off any time a machine goes through a complete strip-down. A cover that no longer sits flush after reassembly usually traces back to a plastic boss that got stripped or over-torqued, and once that happens the fix runs to a larger screw or a thread insert rather than the original size, so driving these by hand rather than with a power driver is the safer habit.
