3/4" X 11" 六角頭方頭螺絲 | 鋼鍍鋅 (50 顆/包)

I needed some serious fasteners for a heavy timber project, and these zinc-plated lag screws drove in cleanly without stripping. The 3/4-inch thickness gave me confidence the connection would hold up to the weather.

The threads bit into the pressure-treated beams cleanly without stripping, and the holding power feels rock-solid after driving them in. I used them to tie together some heavy timber framing, and the zinc finish is holding up nicely against the damp weather.

Perfectly straight threads and sharp points made driving these into pressure-treated 4x4s a breeze with my impact driver. The zinc coating seems solid, no rust after a week of rain.
