M14-2 x 70mm 內六角螺絲 | 六角驅動 | 部分螺紋 | 12.9級合金鋼、熱處理黑色氧化 (25/包)

The black oxide finish on these screws is nice and uniform, giving them a quality look right out of the package. They threaded cleanly into my jig without any binding, which was a relief after dealing with cheaper fasteners. Exactly the precision fit I needed for a tight assembly.

I needed a high-strength fastener for a jig I’m building, and these M14 socket cap screws fit perfectly with their class 12.9 alloy steel rating. The partially threaded design made installation into a tapped hole simple.

The black oxide finish on these screws looks great and seems like it will resist rust well in my shop environment. The hex socket drive made installation really easy with an allen key, and the M14-2 x 70mm size was perfect for a heavy-duty assembly I was working on.
