HOLO-KROME 76279 M8-1.25×80mm 六角穴付きキャップスクリュー | 六角ドライブ | 合金鋼 熱処理黒色酸化被膜 (100個/パック)

I've been using these for jig assembly in my workshop, and the 80mm length gives just enough thread engagement for thick fixtures. The hex socket drive makes them easy to tighten without stripping.

The black oxide finish on these M8s gives them a clean, professional look that resists rust nicely in my shop. I've used a full hundred on tooling fixtures and not a single one has stripped or failed to torque down properly.

These M8s are a solid upgrade for my jigs—the black oxide finish gives them a nice grip in the socket drive without any galling. They press-fit just right in my 8mm holes and hold their torque well.
