M10-1.5 x 70mm ソケットキャップスクリュー | フラットヘッド六角ソケットドライブ | 部分ねじ | クラス12.9 合金鋼 亜鉛メッキ (100 / パッケージ)

Grabbed these for some tooling fixtures and the partially threaded design makes alignment way easier than dealing with fully threaded rods. The zinc plating looks clean and even across all 100 pieces, no burrs on the threads that I could feel.

Used a full box on a custom press jig and every single one seated perfectly without any stripped threads. The zinc coating looks uniform and the hex drive held up well under high torque with no rounding.

The partial threading on these M10 screws made alignment in my jig much easier than fully threaded ones. The zinc coating looks consistent and should hold up well in my shop environment.
