HOLO-KROME 87147 M8-1.25 X 70mm 內六角螺絲 | 平頭六角凹頭驅動 | 合金鋼熱處理黑氧化物 (100個/包)

I needed a batch of strong screws for a jig I was building, and these M8s have a nice even black oxide finish that resisted scratches during installation. The hex socket drive made tightening them into tight spots easy, and all 100 pieces were cleanly threaded with no burrs. They held up perfectly u

Finally a socket cap screw that doesn't strip on me—the black oxide finish gives them a nice, consistent look and the hex drive bit seats perfectly every time. I used a dozen on a press fixture and every one threaded smoothly without binding.

These M8s are the real deal for jig work - the thermal black oxide finish gives them a nice, even look and they've held up perfectly under heavy clamping pressure. Sizing is spot-on and the 100-count box means I'm set for a long time.
