M10-1.5 X 12mm 內六角螺絲 | 圓頭六角驅動 | 全螺紋 | 10.9級合金鋼 熱處理黑色氧化 (200個/包)

I needed some sturdy fasteners for a jig I’m building, and these M10 button heads seated perfectly with a hex key. The fully threaded shaft gripped firmly in pre-tapped holes, and the thermal black coating seems tough enough to handle regular adjustments.

The black oxide finish on these M10 screws is holding up perfectly in my jig setup, no chips or wear after a week of use. They thread smoothly into tapped holes and the Class 10.9 strength gives me confidence for heavier-duty tooling work.

I was nervous about buying 200 screws sight unseen, but the black oxide finish is even and the hex sockets are cut clean—every single one of the first dozen seated perfectly in my fixture jig. Class 10.9 strength gives me real confidence for the tooling work I'm doing.
