M8-1.25 X 20mm 內六角螺絲 | 內六角驅動 | 全螺紋 | 316不鏽鋼 (100 顆/包)

Finally, a box of 316 stainless screws that actually feels marine-grade — the heads are crisp and the threads cut clean into my jig without any binding. I used a full row on a saltwater rig and not a single one showed a hint of rust after a month.

The hex socket drive made installation a breeze with my T-handle wrench, and these 316 stainless screws feel solid enough for outdoor jigs I’m building.

These are exactly what I was hoping for—the 316 stainless steel feels noticeably more corrosion-resistant than the standard 304 stuff I've used before. The hex socket drive fits my Allen key perfectly, and they threaded smoothly into my tooling jig without any binding.
