براغي رأس كبس مقاس #8-32 × 1/2 بوصة | محرك سداسي | صناعة أمريكية | سبائك فولاذ معالجة حرارياً أسود (400/عبوة)

The black oxide finish on these #8-32 socket cap screws looks professional and hasn't shown any wear after tightening a few test assemblies. The hex socket drive seated perfectly on my Allen key without any wobble.

I’ve been using these screws for mounting guides on a drill jig, and the black oxide finish holds up well against minor coolant splashes. The hex socket drive makes them easy to tighten without stripping, even in tight spots.

Installing these into my jig tonight and the hex socket grabs perfectly without stripping. The 400-count package means I won’t have to reorder for a long time.
