براغي آلية M3-0.5 × 5 مم | رأس بان فيليبس | فولاذ مقاوم للصدأ 316 (1,000 / عبوة)

Just finished assembling some outdoor sensor mounts near the coast, and these M3 screws didn't show any rust spots after a week of salt spray. The pan head profile sits flush against the bracket, and the Phillips drive grabbed cleanly without stripping.

I used these on a dock repair project, and the 316 stainless held up perfectly after weeks submerged. The pan head seated flush without stripping, which surprised me for screws this small.

Finally, a screw that doesn't tease me with rust after one season near the coast. The non-magnetic property is a real bonus when working near sensitive electronics on my boat.
