براغي رأس مقبس M4-0.7 × 8 مم | رأس مسطح بمحرك سداسي | ملولبة بالكامل | فئة 12.9 من سبائك الصلب مطلية بالزنك (900 / عبوة)

I needed a solid batch for a jig I was building, and these M4 cap screws held up perfectly on the drill press. The hex socket drive makes installation quick and secure without stripping. For the price per piece, you can't beat the quality.

The hex socket drive sits snugly in my driver with zero stripping, and the zinc plating looks clean and even across all 900 pieces. I've used a few dozen on a jig build so far and the 12.9 alloy steel feels solid under load. For the price per unit, you can't argue with this lot.

Zinc plating looks even and the hex sockets are cut cleanly, so my 2.5mm Allen key seated snugly on every one I’ve used so far. Four stars because a handful had slightly tight threads on first pass, but they work fine once seated.
