براغي رأس كبس مقبس M8-1.25 × 16 مم | محرك مقبس سداسي | ملولبة بالكامل | فئة 12.9 فولاذ سبائكي أكسيد أسود حراري (400/عبوة)

I needed a batch of socket cap screws for a jig build, and these M8-1.25 x 16mm ones with the hex drive are exactly what I was after. The 12.9 alloy steel feels dense and durable, and the black oxide finish seems well applied. For 400 pieces in a single package, this is a solid value.

I've been using these for some jig builds and the hex socket drive feels really solid—no stripping issues at all. The 12.9 alloy steel holds up better under torque than the regular grade bolts I used before.

These are the first M8-1.25 fasteners I’ve bought that actually feel like they’re cut from proper tool steel; the black oxide finish is nice and even across all 400 pieces. They seated perfectly into my jig plate without any binding.
