M3 × 4mm براغي ضبط بنقطة كأسية | فولاذ مقاوم للصدأ 316 (100 / عبوة)

I needed these for a marine repair job and the 316 stainless is definitely holding up better than the old hardware against the salt spray. The socket drive made them much easier to install in a tight spot compared to standard hex screws.

Finally, matching stainless screws for boat hardware that won't pit or rust. The hex socket drive seats perfectly with my M3 bit, making them much easier to torque down than a slotted head. A solid package for the price, especially since 316 is what you need for saltwater.

Exactly the right fit for my 8mm shaft collars, and the cup point bites down firmly without stripping. The 316 stainless finish feels properly marine-grade, no rust worries after a month in a damp workshop.
