M6-1×35mm 六角穴付きボタンヘッドキャップスクリュー | 六角ドライブ | 全ねじ | 12.9級合金鋼 亜鉛メッキ (200本/パック)

Used these to mount a jig fixture on my mill table, and the 12.9 grade grabbed tight without any stripping. The button head profile sits flush enough that I don’t have to counterbore for most setups.

Honestly, I was bracing for a few stripped heads, but the hex drive on these cut cleanly into every single one—no cams, no fuss. Zinc plating is even and uniform, so they look sharp on the jig frame I just finished. For 200 of them, this is the kind of fastener you just buy once and forget about.

Finally got around to swapping out the old hardware on my jig, and these M6 button heads torqued down perfectly without stripping. The hex socket drive made install quick, and the zinc coating on the 12.9 alloy feels nice and sturdy.
