M24-3 X 130mm 內六角螺絲 | 六角驅動 | 部分螺紋 | 8.8 級合金鋼熱處理黑色氧化 (10 個/包)

I needed a set of heavy-duty screws for a custom jig setup, and these M24s fit perfectly into the tapped holes. The black oxide finish looks robust and the partially threaded section made alignment much easier than expected.

The hex socket drive seated perfectly on my torque wrench, and the partial threading gave me just the right grip for a jig I'm building. All ten arrived with a consistent, even black oxide finish and no burrs on the threads. Solid purchase for the price.

The black oxide finish looks sharp and seems tough enough for the dirty workshop environment I work in. Threads on all ten screws were clean and engaged smoothly with my nuts, zero binding. For a 130mm length, they feel incredibly solid in the hand.
