M8-1.25 x 60mm 內六角圓頭螺絲 | 半圓頭內六角驅動 | 全螺紋 | 10.9級合金鋼 熱處理黑色氧化 (100顆/包)

Had to replace some worn screws on a production fixture, and these button heads seated perfectly with the hex driver. The black oxide finish looks clean and the 10.9 grade gives me confidence they'll hold up under load.

Put a new tooling jig together with these and the hex socket drive made installation a breeze. The fully threaded length gave me plenty of grip for a solid hold. Exactly what I needed for heavy-duty assembly work.

The black oxide finish on these M8 screws looks professional and resists corrosion well, and the hex socket drive made installation with my allen key effortless. They fit perfectly in my jig setup and feel dense and solid, just what I needed for a heavy-duty fixture.
