David C. ★★★★★

I was worried about corrosion when building my outdoor pergola, but these 18/8 stainless steel lag screws should hold up perfectly even in the rain. The hex head made driving them in with my impact driver super easy, and the threads bit into the wood with zero stripping.

Ruby ★★★★★

Installed a dozen of these for a deck railing repair and they bit into the pressure-treated wood perfectly without spinning. The stainless steel finish looks clean and I’m glad they won’t rust over time.

James I. ★★★★★

Finally, some hex head lag screws that don't strip out under real torque—these ones held a heavy ledger board to a beam without giving up. The stainless finish is a nice bonus for outdoor projects where rust would be a problem.
