M12-1.75 X 35mm 內六角螺絲 | 六角驅動 | 全牙 | 316 不鏽鋼 (50 顆/包)

Trying to find corrosion-resistant fasteners for a marine jig was a chore until I grabbed these. The 316 stainless steel gives me real confidence they won't rust out, and the threads cut cleanly into the tapped hole.

The hex socket drive seated my Allen key perfectly with zero stripping, and the 316 stainless finish looks clean against the machine frame. Threading was smooth all the way down, no binding or burrs on any of the fifty. These are holding up great on my jig setup so far.

Used them to replace some old fasteners on a boat trailer and the 316 stainless is already proving its worth against the saltwater. The hex socket drive made installation easier than I expected, no stripped heads.
