HOLO-KROME 72090 براغي رأس أسطوانية مقاس 1/4-20 × 3/8 بوصة | محرك سداسي | فولاذ سبائكي مؤكسد أسود حراريًا (100 / عبوة)

Just finished mounting a new jig and these little guys threaded in smooth with no binding at all. The black oxide finish looks clean and seems like it'll resist rust well on my shop fixtures.

The hex drive on these 1/4-20 screws is crisp and precise—they seated perfectly in my jig without any cam-out or stripping. Exactly the kind of reliable hardware you want for tooling builds.

The black oxide finish feels like it’s going to hold up well in my shop, and the hex sockets grabbed my allen key cleanly on all 100 pieces without a single stripped head. These are exactly what I needed for tightening down some tooling plates.
