براغي رأس سداسي M4-0.7 × 18 مم | فئة 8.8 من الصلب مطلي بالزنك | ملولبة بالكامل (1000 / عبوة)

Had to replace a bunch of stripped bolts on an old assembly line jig, and these M4-0.7 screws threaded in perfectly with zero issues. The zinc plating looks uniform and hasn't shown any rust after a week in a damp shop.

Used these to secure a jig on my drill press and the hex head held up perfectly under torque from a socket wrench. The zinc coating on an M4 screw feels more substantial than the plain steel ones I've used before.

Threaded all the way to the head, which made installing them in a tight equipment panel much easier than expected. The zinc coating looks uniform and clean, and every single one of the thousand screws threaded smoothly without any burs.
