M8-1.25 x 60mm ソケットキャップスクリュー | 六角穴付きボタンヘッド | 全ねじ | 10.9級合金鋼 熱処理黒色酸化皮膜 (100本/袋)

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.
