M14-2×35mm ソケットキャップスクリュー | フラットヘッド六角穴付き | 全ねじ | クラス10.9 合金鋼 サーマルブラックオキサイド (50個/パッケージ)

These M14 screws seated flush in my jig's counterbores perfectly, the hex socket drove true without any cam-out. The 10.9 hardness rating gives me confidence they'll hold torque under heavy loads.

The black oxide finish wiped clean easily and left zero residue on my jig plate—these threads seated perfectly in the M14 holes without any binding. Fit and finish are exactly what I wanted for a precision assembly, and the hex socket drive took torque without stripping.

Had no trouble threading these into a custom jig for a milling machine rebuild; the hex drive seated perfectly without stripping. They're definitely heavy-duty enough for the torque I needed.
