5/8-11 X 10" 內六角螺絲 | 六角驅動 | 18/8 不鏽鋼 (10/包)

I needed a long socket cap screw for a custom jig, and the 10-inch length on these 18/8 stainless steel ones was perfect—the hex drive gripped firmly without slipping. Definitely a solid upgrade from the weaker bolts I’ve used before.

Finally, a cap screw that doesn't round out under heavy torque—the 18/8 stainless held up perfectly through a full day of jig assembly. The 10" length was exactly what I needed for a deep fixture, and all ten threads were clean with no burrs.

The hex socket drive grabbed my Allen key cleanly every time, no stripping even after torquing these down on a heavy fixture. All ten threads were flawless out of the pack, and the 18/8 finish hasn't shown a speck of rust after a week of coolant splashing around them.
