M8-1.25 x 35mm 內六角螺絲 | 平頭內六角驅動 | 全牙 | 12.9級合金鋼熱處理黑色氧化 (200/包)

Was installing a new tooling fixture and these flat heads sat flush just like I needed. The black oxide finish looks professional and the hex socket drive made tightening them in tight spaces a breeze.

The hex socket drive bites perfectly for torquing them down in tight spots, and the black oxide finish looks clean on my tooling fixture. All two hundred arrived with threads running smooth end to end; I’ve already used a dozen and none have stripped.

These screws fit snugly in my jig setup with no wobble. The black oxide finish looks clean and seems durable.
