#3 × 2-1/2" مسامير تأخير ذات رأس سداسي | فولاذ مجلفن بالغمس الساخن (100/عبوة)

Installed these on a wooden gate frame and all 100 bolts were consistent in thread depth and finish. The hot-dip galvanizing looks like it'll hold up well in the weather.

The hex head grabbed a socket wrench perfectly for the machinery mount I’m working on, and the hot-dip galvanizing looks like it’ll shrug off rust for years. Just got the box in, all 100 threads are clean and bite straight into the wood without splitting.

Used these to anchor a workbench frame to the concrete floor, and the hex head made driving them in with a socket a breeze. The hot-dip galvanized coating seems thick enough to resist rust even in my damp basement.
