Wedge Anchor, 3/4"x8-1/2"

The WA34*812 CONFAST® Wedge Anchor is a heavy-duty concrete anchor designed for strong, permanent fastening into solid concrete surfaces. Measuring 3/4 in. diameter by 8-1/2 in. length, this anchor provides high holding strength for structural and equipment mounting applications. Constructed from zinc-plated carbon steel, it offers dependable corrosion resistance in dry environments, while the expansion wedge design ensures a tight, secure grip once installed.
