M14-2 X 150mm 內六角螺絲 | 內六角驅動 | 部分螺紋 | Class 12.9 合金鋼熱黑氧化 (25入/包)

The black oxide finish on these M14-2 screws looks professional and resists wear well, even after tightening with a hex key. They’re perfect for securing jig parts where I need consistent torque without stripping.

Finally, socket cap screws that fit like they should — the hex socket drive seated perfectly with my Allen key, no stripping or rounding on the first few uses. Machining a fixture plate with these 150mm lengths felt solid, and the partially threaded section gave me exactly the grip I needed without

The partially threaded design made aligning these in my jig a breeze, and the black oxide finish looks clean and durable. They fit perfectly into my machinery setup without any wobble.
