M18-2.5×120mm 六角穴付きボルト | クラス10.9鋼 亜鉛メッキ | 半ねじ (25本/パック)

The hex head grabs a socket perfectly, no rounding worries. These M18-2.5 screws feel tough and the zinc plating looks solid, even holding steady on my heavy press jig.

I needed some strong fasteners for a repair on a piece of farm equipment, and these class 10.9 bolts are solidly built with a nice, even zinc coating. The partial threads grabbed cleanly on the cast iron part, and the hex heads held up perfectly under my impact wrench without stripping.

The partial threading on these M18 bolts makes alignment a breeze in tight spots. The zinc plating looks clean and durable, and the hex head gripped my socket without any slipping. Exactly what I needed for heavy equipment assembly.
