Victoria S. ★★★★★

I needed heavy-duty fasteners for a cedar deck rebuild and these 316 stainless lag screws threaded in cleanly without any stripping. The hex head made driving them with a socket effortless, and the corrosion resistance gives me peace of mind in wet weather.

Miles S. ★★★★★

Installed these to secure a heavy wooden gate, and the 316 stainless steel gives me real peace of mind in our coastal weather. The threads bite cleanly without needing to pre-drill larger than I expected.

James Z. ★★★★★

Used these for a timber frame tie-in on our deck and the 316 stainless is exactly why I picked them—no rust worries even in coastal weather. The 4-1/2 inch length grabbed deep into the beam, and all 100 came out perfectly threaded. Solid holding power for the heavy connections I needed.
