براغي رأس أسطواني M16-2 X 110 مم | محرك سداسي | خيط جزئي | فولاذ سبائكي فئة 8.8 أسود حراري (25 / عبوة)

I needed a handful of strong, partially threaded bolts for a jig, and these M16-2 x 110mm screws with the hex socket drive fit the bill perfectly. The 8.8 alloy steel feels sturdy, and the 25-piece pack gives good value for small projects.

The black oxide finish on these screws is really uniform, and the hex socket engaged perfectly with my driver without any wobble. Used them to rebuild a press fixture, and the partially threaded design held tight even under heavy load. Very pleased with how clean the install turned out.

I needed a dozen for a heavy-duty jig I was welding up, and the partial threading made final adjustments much easier than expected. The 8.8 alloy steel feels plenty strong for a tooling fixture.
