براغي رأس سداسي M4-0.7 × 40 مم | فولاذ مقاوم للصدأ 18/8 | ملولبة بالكامل (300/عبوة)

Finally tracked down quality M4 hardware that doesn't strip when torqued down. The 18/8 stainless steel threads cut cleanly into pre-tapped holes without galling. A full 300-piece pack should last me through several equipment builds.

The hex heads on these are crisply machined, so my wrench seats without any wobble, and the 18/8 stainless gives them a clean, corrosion-resistant finish. I've already used about fifty of them across a couple of machine builds, and every single thread has started cleanly.

These hex screws are exactly the consistent length and clean threading I needed for rebuilding part of a jig. The 18/8 stainless feels solid and the hex head grabs my socket perfectly without stripping. Packed well, no damaged threads out of three hundred.
