M6-1 X 8mm 內六角螺絲 | 低頭六角驅動 | 全螺紋 | 10.9 級合金鋼熱黑氧化 (300 入/包)

These low-profile heads are perfect for tight clearance spots on my CNC jigs, and the hex drive bites cleanly each time. The 300-count package is a solid value for machine builders.

The black oxide finish on these M6 screws has held up well during assembly, no chipping or flaking. They seated perfectly into my jig fixture with a standard hex key.

Exactly the right head height for tight spots on my jig setup, and the black oxide finish looks consistent across all 300. Threads were clean and started without any binding, and the hex socket drove smoothly.
