3/4 × 12 بوصة براغي تأخير رأس سداسي | فولاذ مقاوم للصدأ 316 (15/عبوة)

Installed these in a treated lumber dock I'm building, and the 316 stainless steel already looks like it’ll outlast the wood. The threads cut smoothly without any binding, which was a relief with such long screws.

These held up great through a wet spring on my cedar fence gate—the 316 stainless is noticeably shinier than the zinc-coated ones I used before. The 12-inch length gave plenty of bite into the posts, though I had to pre-drill every single hole.

Installed three of these in a treated timber pergola, and the 316 stainless held up perfectly through a heavy rain week. The threads bit cleanly without splitting the wood.
