M6-1 X 30mm 기계용 나사 | 팬 헤드 필립스 드라이브 | 316 스테인리스 스틸 (200 / 팩)

I needed stainless steel fasteners for a dock repair project, and these M6 screws held up perfectly after a week of tidal saltwater exposure without any signs of rust. The Phillips drive seated firmly without cam-out, and the 30mm length was just right for securing through 1/2-inch pressure-treated

Used these to replace some deck hardware near the coast, and the fact they're non-magnetic already tells me the 316 grade is legit. The Phillips head seats the driver nicely without stripping, even on a few I had to torque down. Pack of 200 means I've got plenty left for future projects.

These are exactly what I needed for a deck repair near the coast—the non-magnetic 316 steel is a huge plus. The Phillips heads grab the driver bit securely, and the 30mm length fits perfectly with the marine-grade washers I'm using.
