براغي ذات رأس أسطواني M30-3.5 × 160 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي من الفئة 12.9 مع أكسيد أسود حراري (5 / عبوة)

The black oxide finish on these screws is a nice touch—they look properly industrial and slide into the hex driver without any fuss. The partially threaded length gives me just enough grip for a heavy jig I'm building, and the 12.9 alloy steel feels rock solid in hand.

I needed a longer partially threaded screw for a jig I was building, and these M30s fit the bill perfectly with their hex socket drive making installation simple. The 160mm length gave me just the right reach without any wobble.

The black oxide finish on these screws looks even better in person, and the hex socket drive seated my Allen key perfectly with zero wobble. I used them to bolt down a heavy jig plate and the 160mm length gave me plenty of grip without any thread binding.
