مسامير تأخير مقاس #5 × 4-1/2 بوصة | رأس سداسي | فولاذ مطلي بالزنك (100 / عبوة)

The threading was clean and consistent on every bolt, so they all started easily in the pre-drilled holes. I used them to secure a heavy workbench frame and they held tight with no stripping.

The hex head made it easy to get a solid grip with my socket wrench when securing a steel beam to a wooden frame, and the zinc plating looks clean. Threads cut smoothly into the wood without any stripping.

I used these to fasten a heavy wooden beam to a concrete wall, and the 4-1/2 inch length gave me plenty of bite. The hex head made driving them with a socket really easy, even in tight spots.
