#4 × 1/2" براغي قطع خيوط من النوع 25 | رأس مسطح مع محرك فيليبس | فولاذ مع زنك ثلاثي التكافؤ (2000 / عبوة)

The trivalent zinc finish on these screws is holding up perfectly in my damp basement workshop, no rust after two weeks. Used them to attach a metal bracket to a wooden frame, and the self-tapping tip grabbed instantly without pilot holes. Exactly what I needed for small electronics assembly work.

Picked up a box of these #4 screws for some small electronics enclosures, and the flat head sits perfectly flush without splitting the plastic. The phillips drive grabs well without camming out, which is nice when you're driving dozens at a time.

The trivalent zinc finish on these screws gives me confidence they won't rust in my workshop projects. They drove cleanly into some thin steel tubing without stripping the heads. A solid choice for general assembly work.
