M10-1.5 x 150mm 內六角螺絲 | 六角驅動 | 全螺紋 | 316不鏽鋼 (25 / 包)

I needed long screws for a marine railing repair, and these fully threaded 316 stainless ones threaded smoothly into the pre-tapped holes without binding. The hex socket drive made installation straightforward with just a standard allen key.

Pulled these out of the package and the threading is perfectly clean, no burs or rough edges. They seated smoothly into tapped holes on my welding fixture, and the 316 stainless feels solid for outdoor use.

Installed these on a custom jig frame and the 316 stainless held up perfectly during a wet test. The hex socket drive makes tightening them in tight spots much easier than a regular bolt.
