M6-1 x 50mm 六角穴付きボルト | クラス8.8 鋼 無処理 | 部分ねじ (400本/パック)

I was short on bolts for a jig and these M6-1x50mm hex heads fit my frame perfectly. The partially threaded section made alignment easier, and the 400-pack means I’m set for more projects.

Class 8.8 steel means these screws hold tight without stripping, which is exactly what I needed for a heavy equipment frame. The 50mm length with partial threads gave me solid bite without bottoming out. Wrench fit was snug on every single one across the whole 400 count.

The partial threading on these M6 screws makes alignment so much easier when I'm assembling equipment frames, and the 400 count means I won't run out mid-project. The 8.8 steel feels solid under the socket wrench without any stripping so far.
