براغي رأس أسطوانية M4-0.7 × 18 مم | رأس مسطح محرك سداسي داخلي | ملولبة بالكامل | فولاذ مقاوم للصدأ 18/8 (800/عبوة)

Used these on a small jig I was building, and the hex socket drive made installation much easier than with Phillips heads. The threads were clean and consistent across all 800 pieces, which saved me a lot of time sorting through a batch.

I was pleasantly surprised by how uniform the threading is across all 800 screws—makes assembly much faster when they all seat evenly. The flat head sits flush in counterbores without any wobble, which is essential for my jig builds.

I've been using these screws for building small jigs and the uniformity across the entire 800-piece pack is impressive. The 18/8 stainless steel feels solid and the flat head sits perfectly flush in my work.
