M4-0.7 X 35mm 機械螺絲 | 盤頭十字驅動 | 316不鏽鋼 (400個/包)

These screws are perfect for my boat’s deck hardware; the 316 stainless is noticeably tougher than the old 304 bits I used before. The pan head sits flush and the Phillips drive bit grabbed nicely without stripping. Really solid for marine use.

I was a little worried about finding the right screws for mounting a saltwater fishing rod holder, but these M4-0.7 pan heads threaded in perfectly with a standard Phillips driver. The 316 steel feels solid and the 35mm length was just right for my application.

Used these on a boat railing repair, salt air hasn't touched them after three months—the 316 steel feels rock solid and they seat cleanly with a standard Phillips bit. The 35mm length was perfect for the bracket, though I wish I'd ordered two packs of these.
