#1 × 1-1/4" مسامير تأخير | رأس سداسي | فولاذ مطلي بالزنك (1000/عبوة)

Installed a whole bunch of these into joists for a deck rebuild and not a single one stripped out. The zinc coating seems even and should hold up well in covered outdoor use.

The hex heads grabbed my socket wrench cleanly on every single one I drove in—no stripped corners across the first two hundred. Zinc plating looks uniform and should hold up fine for framing interior walls.

Bought a full thousand-count box for a deck rebuild, and every single bolt threaded cleanly into the pilot holes without any binding. The zinc coating is smooth and uniform, so they should hold up well against moisture.
