براغي رأس أسطوانية M16-2 × 95 مم | محرك سداسي | جزئية الخيوط | فولاذ سبائكي فئة 12.9 مطلي بالزنك (25/عبوة)

The hex socket drive gives a clean grip without stripping, and the zinc plating looks solid on my machine tools. These M16 screws fit perfectly into my precision assembly jigs.

I needed these for a jig I was building in the shop, and the hex socket drive made installation straightforward. The partially threaded design gave me just the right grip for securing heavy steel plates.

Threads were clean and the zinc plating is even, no rough edges. The hex socket seated my Allen key perfectly with zero wobble, and the 12.9 alloy steel feels seriously rigid for my jig builds. Just the right amount of thread for clamping down.
