3/8-16 X 10" 內六角螺絲 | 六角驅動 | 部分螺紋 | 合金鋼熱處理黑色氧化 (3個/包)

Needed exactly 10 inches for a jig I was building, and these came in at the perfect length with clean threads all the way. The hex socket drive made installation much easier than a standard hex head bolt would have been in that tight spot.

Installed these in a jig for a repetitive drilling operation and the hex drive made torquing them down much easier than a standard hex head. The partially threaded design let me get precise clamping depth without bottoming out the threads.

The black oxide finish on these screws is holding up perfectly in my jig setup, no rust or wear after a week of use. The hex socket drive makes them easy to install even in tight spaces.
