Benjamin ★★★★★

Used these for a dock repair and the 316 stainless held up perfectly against the saltwater spray. The extra length gave me a solid bite into the pressure-treated timbers, and they drove in straight without any wobble.

Ryan O. ★★★★★

Six inches of 316 stainless gives me real peace of mind on these timber ties—no worrying about rust streaks down the post. Drove them in with a socket and they bit deep without stripping, and the full box of 250 should last me through every project this year.

Adam ★★★★★

These 316 stainless lag screws are perfect for my deck project—they drove in cleanly without any stripping. The corrosion resistance gives me peace of mind for outdoor use, and the 6-inch length provides serious holding power for the heavy timber beams.
