#10-24 x 3" 內六角螺絲 | 平頭內六角 | 部分螺紋 | 合金鋼熱處理黑色氧化 (100 / 包)

The hex socket drive seated perfectly on my Allen key with zero stripping, and the black oxide finish has held up nicely against shop grime. These are solidly built and the partial threading gives just the right grip for my jig setup.

The partially threaded shank on these screws made them grip perfectly in the jig I was building, and the black oxide finish feels durable. They seated flush with just a hex key, no stripping issues.

I needed some flat head hex screws for a jig I was building and these #10-24 x 3" ones seated perfectly flush with a standard hex key, the thermal black oxide coating feels durable and hasn't shown any wear yet.
