براغي ضبط مقبس كوبية HOLO-KROME 32194 7/16-14 × 7/16" | فولاد سبائكي مع أكسيد أسود حراري (100/عبوة)

I needed these for a jig I was building, and the hex socket drove in perfectly without stripping. The cup point bit into the shaft just as it should, giving me a solid hold.

These little cup points bite into the shaft exactly where I need them, and the hex socket drive makes install in tight spots a breeze. The black oxide finish on all 100 pieces looks consistent and should hold up fine in my shop.

Got my 100-count box and the cup point bites into shafts exactly as it should. The black oxide finish looks consistent across all of them, though a couple had a tiny bit of burr I had to knock off before threading. Fine for the price.
