براغي رأس مقبس M20-2.5 × 55 مم | محرك مقبس سداسي | ملولبة بالكامل | فئة 8.8 سبيكة فولاذ مطلي بالزنك (20 / عبوة)

The hex socket drive seated perfectly with my Allen key, and the zinc plating looks clean and even across all twenty pieces. Threading them into my jig setup was smooth, no binding or galling on the 8.8 alloy steel. Exactly the precision feel I want for tooling work.

I needed some high-strength bolts for a jig I'm building, and these M20s with the full threading made assembly so much easier. The zinc plating looks uniformly applied, and they threaded into tapped holes without any binding.

The hex socket drive seated perfectly on my breaker bar, no stripping or wobble during install. Zinc plating looks clean and even across all twenty, though I wish the thread engagement felt a touch smoother. Solid for jig work where you need that full thread grip.
