Customer Reviews (4.6 / 5 · 5 reviews)

Timothy ★★★★★

The threads bit into the pressure-treated oak cleanly without stripping, and the 316 stainless finish gives me peace of mind for a dock project that sees saltwater every tide. I've already got a second box on order for the next phase.

Christopher G. ★★★★★

Used these to secure a heavy timber pergola frame—the 316 stainless held up perfectly after a week of coastal rain. The extra length really bites into the wood, and the hex head made installation a breeze with just a socket wrench.

Olivia ★★★★★

These 316 stainless lag screws drove in cleanly without any binding, even into dense oak. The hex head gave my socket a solid grip, and I’m confident they’ll outlast the weather.
