براغي ذات رأس أسطواني M6-1 × 6 مم | محرك سداسي برأس دائري | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (400/عبوة)

For my latest project jig, these hex socket screws seated perfectly without any cam-out—the 12.9 alloy steel feels seriously tough. The zinc plating looks clean and uniform across all 400 pieces, which is exactly what I needed for repeatable precision assemblies.

I was pleasantly surprised by the packaging—every screw was neatly separated in the box, so I didn’t have to sort through a jumbled mess. The 12.9 alloy steel feels solid, and they fit perfectly into my jig without any stripping.

The hex socket drive makes these a breeze to install in tight spots on my jig. For the price, getting 400 pieces in class 12.9 alloy steel is a solid deal.
