براغي آلية 5/16-18 X 3" | رأس دائري بمحرك مشقوق | فولاذ مقاوم للصدأ 18/8 (100/عبوة)

I picked these for a heavy-duty outdoor project where corrosion resistance was a must, and the 18/8 stainless steel has held up perfectly through a few rainstorms. The 3-inch length gave me just the right grip for fastening into pressure-treated lumber.

The slotted heads on these 5/16-18 screws bit nicely into my driver without slipping, and the stainless steel feels solid for outdoor use. Perfect length for securing some heavy brackets on the deck.

Finally, a machine screw that doesn't rust after a season outdoors—the 18/8 stainless finish has held up perfectly on my gate hinges through all the rain. The 3-inch length gave me just enough thread engagement for a solid grip, and being non-magnetic made handling them a breeze.
