براغي رأس أسطوانية M6-1 × 18 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 8.8 بأكسيد حراري أسود (600 / عبوة)

The hex socket drive on these caught the thread perfectly without any cam-out, which is exactly what I needed for a few jigs I’m building. I’ve used maybe 200 of the 600 so far and every single one has seated cleanly. They’re a solid buy for the price.

For my jig setup, these threaded all the way in without a single hiccup—the hex socket drive seated perfectly every time. Having 600 in one box means I won't be scrambling for fasteners mid-project, and the black oxide finish looks clean against the steel.

The thermal black oxide finish on these M6 screws provides excellent corrosion resistance for my jig builds. They drive smoothly with a hex key and the threading is crisp, making assembly quick and reliable. A solid upgrade for precision fixtures.
