3/8" × 4-1/2" براغي لولبية سداسية الرأس | فولاذ مقاوم للصدأ 18/8 (200 / عبوة)

Finally got these installed on a dock repair project and the hex heads seated perfectly with a socket wrench. The 18/8 stainless gives me real peace of mind against rust in the salt air.

I needed 18/8 stainless for a coastal deck repair and these hex heads drove in smoothly without stripping. They’re holding tight against the salt air so far.

Used a full box of these on a cedar pergola and not a single one stripped or snapped, even with the 3/8" diameter going into dense oak. The 18/8 stainless is already showing zero rust after a couple weeks of rain, which is more than I can say for the coated ones I've used in the past.
