M14-2 X 55mm 六角穴付きキャップスクリュー | 六角穴ドライブ | 全ねじ | クラス12.9 合金鋼 亜鉛メッキ (50個/パック)

The hex socket drive on these M14-2 x 55mm screws grips the driver perfectly without any cam-out—critical for jig assembly. Threads are sharp and consistent, and the zinc plating looks clean and uniform across all 50 pieces.

I needed a batch of M14-2 x 55mm screws for a jig rebuild, and these Class 12.9 alloy steel ones cut through the old threads without any stripping. The zinc plating has a nice uniform finish that should hold up well in my shop.

The hex socket drive seated perfectly with my Allen key, no stripping or wobble even under a stubborn load. Zinc plating looks uniform across all 50 pieces, and the 12.9 alloy steel feels reassuringly rigid. These are doing exactly what I need for a precision fixture.
