HOLO-KROME 86724 7/16-14 X 5" 內六角螺絲 | 內六角驅動 | 合金鋼熱處理黑色氧化 (25 / 包)

Used these to secure a new jig setup on my mill, and the hex socket drive made installation quick with a ball-end driver. The threads were clean and ran in smoothly without binding. Exactly what I needed for precision work.

The black oxide finish on these 7/16"-14 screws is holding up perfectly in my jig setup, no rust or wear after a month of use. Exactly the length I needed for thick material.

Had to swap out some worn bolts on my milling machine’s indexing table, and these socket caps bottomed out perfectly with no wobble. The black oxide finish feels grippy in the hex wrench, and the threads cut cleanly into the threaded holes.
