براغي رأس مقبس M4-0.7 × 14 مم | محرك مقبس سداسي | ملولبة بالكامل | فئة 8.8 سبيكة فولاذ مطلي بالزنك (900 / عبوة)

The hex socket drive sits perfectly flush in my jig setup, and the fully threaded body threads in cleanly every time. These alloy steel screws held tight through multiple assembly cycles with zero stripping.

I needed to swap out a stripped screw on a jig I use daily, and these M4s threaded in cleanly with no binding at all. The hex socket drive seated perfectly with my Allen key, and at 900 per pack I won't worry about running out anytime soon.

Used a full bag of these for a custom jig build, and every single screw threaded smoothly into tapped holes without any binding. The zinc plating gives them a clean, consistent finish that resists fingerprints better than I expected.
