DEWALT POWER-STUD+ SD1 1" X 12" (Box of 5)

The POWER-STUD+ SD1 1" X 12" is a heavy-duty through-bolt expansion anchor built for high-load fastening into solid concrete and block. Made from zinc-plated carbon steel, it expands against the sides of the drilled hole as the nut is tightened, creating a strong mechanical bond ideal for structural connections, ledger boards, and equipment mounting. A contractor-grade choice that's just as manageable for a DIY installer with a standard wrench and hammer drill.
