DEWALT Power-Stud+ SD4 304SS 1/4" x 3-1/4" (Box of 100)

The POWERSTUD+ 304SS 1/4IN X 3 1/4IN is a heavy-duty through-bolt expansion anchor built for high-load fastening into solid concrete and block. Made from 304 stainless 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.
