براغي ذات رأس أسطواني M4-0.7 × 8 مم | محرك سداسي | ملولبة بالكامل | فئة 8.8 من سبائك الفولاذ مطلية بالزنك (800 / عبوة)

Pulling these out of the box, the hex socket drive engages perfectly with my Allen key—no stripping. They threaded cleanly into my precision assembly without any binding. Exactly the consistent quality I needed for a batch of tooling fixtures.

I needed a decent quantity for a jig I’m building, and the zinc plating on these screws looks clean and even. The hex socket drove in smoothly with no cam-out, and the threading felt precise.

Installing jigs for a small production run and these M4 socket caps seated perfectly with my hex driver. The 8.8 alloy steel feels solid and the zinc plating looks clean. A full 800 pack means I won’t run out mid-project.
