براغي تأخير ذات رأس سداسي 1/2 بوصة × 1-1/2 بوصة | فولاذ مقاوم للصدأ 316 (250/عبوة)

Used these to fasten a heavy pergola beam to a post, and the 316 stainless is already holding tight through a rainy week. No rust or binding during install.

Installed a bunch of these into treated 4x4 posts for a deck railing, and the 316 stainless steel is a serious upgrade over regular coated screws. No rust worries after a few rainstorms, and the hex head bites in perfectly with a socket.

Used these for a dock repair project, and the hex head made driving them into pressure-treated lumber much easier than I expected. They haven't shown a spot of rust after a month in saltwater.
