3/4-10 X 2-1/2" 內六角螺絲 | 低頭六角驅動 | 合金鋼熱處理黑氧化物 (10 / 包)

I needed something with decent grip for a jig I was building, and the black oxide finish on these gave them a nice, durable look right out of the package. They threaded cleanly into tapped holes with no binding at all.

The low head profile on these screws let me fit them into a tight jig assembly where standard caps would have stuck out too far. Threads ran smooth and the black oxide looks consistent across all ten pieces.

The black oxide finish on these socket cap screws is holding up great in my jig assembly — no stripping during install. They fit perfectly into the tight spots where a standard hex head wouldn't work. Exactly what I needed for this tooling project.
