5/8-11 X 12" 插座螺帽螺絲 | 六角驅動 | 18/8 不鏽鋼 (10 / 包)

Needed a full dozen for a custom press fixture, and these 12-inch screws threaded in smoothly with no binding. The hex drive socket was deep and clean, accepting the Allen key easily. Solid value for stainless steel hardware this size.

Installed these in a heavy-duty jig I’m building, and the hex socket drive made tightening them down in tight spaces a breeze. The 12-inch length gave me plenty of thread engagement for a rock-solid assembly.

I needed long, strong bolts for a custom jig and these 12-inch socket cap screws fit the bill perfectly. The 18/8 stainless steel feels solid and corrosion-resistant, and they threaded smoothly without binding. A bit pricey for ten pieces, but definitely heavy-duty enough for precision assemblies.
