HOLO-KROME 76856 M14-2 X 120mm 內六角螺絲 | 六角驅動 | 合金鋼熱處理黑色氧化 (10顆/包)

I needed some strong cap screws for a jig build, and these M14-2 x 120mm threaded in perfectly without any binding. The hex socket drive gave me a solid grip with my Allen wrench, and the black oxide coating seems durable so far.

I needed some heavy-duty bolts for a jig I was building, and these M14x120mm screws fit perfectly with no slop in the drive. The hex socket gripped firmly, and the black oxide coating looks clean and professional.

The thermal black oxide finish on these M14 screws gives them a nice, consistent look, and they seated perfectly into my jig setup without any binding. I've already put them through a few heavy cycles and the heads are holding up without any wear at the drive socket.
