براغي رأس كبس M5-0.8 × 15 مم | محرك رأس مسطح سداسي | ملولبة بالكامل | فئة 12.9 فولاذ سبائكي مطلي بالزنك (600 / عبوة)

Used a handful of these to replace the stripped bolts on my milling machine clamp set, and the hex socket drive made installation quick. The 12.9 grade alloy steel feels tougher than the cheap hardware I was using before. For the price of a bulk pack, I'm set for years.

Installed these in a jig I’m building, and the hex socket drive seated perfectly with no cam-out. The zinc plating looks consistent across all 600 pieces, which is rare for bulk hardware.

The threads on these are clean and uniform across the whole box, so they drive in smoothly without any binding. The zinc plating is even and bright, which should hold up well in a machinist's cabinet. Exactly what I needed for my fixture plates.
