براغي تأخير رأس سداسي 1/2 × 4 بوصة | فولاذ مقاوم للصدأ 18/8 (150 / عبوة)

The threads started cleanly with a socket wrench, and the flat hex head grabbed tight without slipping. I replaced rusted carriage bolts on a dock with these and they haven't budged after three weeks of rain. Solid holding power for heavy timber framing.

Used these to fasten some heavy pergola beams to the posts, and they drove in cleanly without any stripping. The stainless steel heads look great and give me real confidence they won't rust out in the weather.

Bought a box of 150 for a deck repair and the 18/8 stainless steel gives me real peace of mind against rust in wet weather. They drove in cleanly and hold the beams rock-solid, even with my impact driver. Exactly the heavy-duty grip I was hoping for.
