3/8" × 4-1/2" براغي تأخير رأس سداسي | فولاذ مقاوم للصدأ 316 (200 / عبوة)

Installed these to secure some heavy joists for a deck rebuild, and the 316 stainless really gives me peace of mind against salty coastal air. The hex head made driving them in with a socket effortless.

I've used a lot of lag screws for docks and outdoor frames over the years, and the 316 stainless is exactly what you need if salt or constant moisture is a concern. These are the first ones I haven't seen any surface rust on after a full season outside, and the 4-1/2" length gives real bite in a 6x6

I was a little worried the hex head might strip under torque, but they drove in clean and held tight for my deck joists. The 316 stainless feels heavy-duty and definitely won't rust in this coastal weather.
