HOLO-KROME 87124 M8-1.25 X 16mm 內六角螺絲 | 平頭六角驅動 | 合金鋼熱處理黑氧化物 (100 顆/包)

The black oxide finish on these M8 screws gives them a consistent, non-reflective look that blends right into my jig builds. All 100 pieces packed in the box had clean threads with no burs, and the socket drive seated the flat head perfectly on the first try.

The flat head sits perfectly flush in my counterbores, which made aligning these on my jig plate a breeze. The black oxide finish has a nice matte look and they threaded in cleanly without any binding.

Used these on a fixture rebuild and the hex socket drive held up perfectly under repeated torquing without any stripping. The black oxide finish gave them a clean, uniform look against the steel plate.
