براغي رأس كبس M4-0.7 × 8 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي درجة 8.8 مع أكسيد أسود حراري (1200 / عبوة)

Just finished a jig build that needed a pile of these, and the Class 8.8 alloy steel feels reassuringly tough for the price. The black oxide finish gave them a nice, uniform grip right out of the bag, and the hex socket seated cleanly on every single drive.

I needed a full box of these for a jig I’m building, and the 1200 count saves so much time versus buying smaller packs. The hex socket drive fits my standard Allen key perfectly, and they threaded cleanly into steel without any stripping.

The black oxide finish on these screws looks great and seems like it'll resist rust in my workshop. I used them for a jig I'm building and the hex socket drove in cleanly without stripping.
