5/8-11 X 4-1/2" 插座蓋螺絲 | 六角插座驅動 | 部分螺紋 | 316不鏽鋼 (10個/包)

The hex socket drive made tightening these into my jig incredibly easy, and the partial threading helped them grip perfectly without stripping the stainless.

Finally a cap screw that doesn't seize up after a few months outdoors—I used these to repair a gate hinge near saltwater, and the 316 stainless steel threads still look clean. The hex socket drive made installation easy with a standard Allen key.

Installed these on a marine railing and the 316 stainless held up perfectly against salt spray. The hex socket drive made torquing them down much easier than using a hex key on a standard bolt.
