DEWALT 3/4"x 6-1/4" SD1 Domestic Wedge Anchor (Box of 20)

The 3/4"x 6-1/4" SD1 Domestic Wedge Anchor 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.
