Evelyn ★★★★★

I've been building a timber frame shed, and these 18-inch stainless steel lag screws drove in smoothly with a impact driver without stripping. The 5/8" diameter gives me real confidence in the connections, plus the corrosion resistance is a must for outdoor use.

Joshua E. ★★★★★

I used these 5/8" lag screws to fasten heavy timbers for a deck frame, and the 18/8 stainless steel gives me peace of mind against rust. The heads are easy to drive with a socket wrench, and the 18-inch length grabbed deep into the wood.

Richard ★★★★☆

I was pleasantly surprised by how cleanly the 18/8 stainless steel holds up after a few weeks outside, no rust spots yet. The hex heads seated nicely with my socket set, though I wish the package had a few more screws for the price.
