براغي رأس تجويف M4-0.7 X 25mm | رأس مسطح محرك سداسي تجويف | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (600 / عبوة)

I needed a full bag of these for a jig build, and the hex socket drive makes them much easier to tighten in tight spots than a standard slot.

Swapping out old machine screws for these M4-0.7 x 25mm flat head hex socket ones was a breeze—the hex drive grabs perfectly without stripping. The 316 stainless finish feels solid, and for a full pack of 600, the price is tough to beat.

For a 316 stainless fastener this price is almost suspicious, but the hex socket drive is crisp and the threads cut cleanly on the first pass. Put a hundred into a precision assembly without a single stripped head or binding issue. These are going into my permanent stock.
