The Simpson Easy-Set 5/8 in. x 4-3/4 in. Pin-Drive Expansion Anchor from Simpson is built for medium- and heavy-duty fastening applications into concrete, concrete masonry unit (CMU), and brick. Its pin-drive expansion mechanism delivers reliable holding power by expanding within the base material, creating a strong mechanical connection suited to demanding masonry and structural tasks. The anchor ships with an integrated nut and washer already in place, so installers can move quickly from drilling to setting without managing loose hardware.

Key Features

• Integrated nut and washer - keeps all components together as a single assembly, reducing the chance of lost parts and speeding up installation on the job site
• Pin-drive expansion mechanism - expands against the walls of the drilled hole to provide a strong, secure connection to concrete base materials, including CMU and brick
• Carbon steel construction with Yellow-Zinc Dichromate Plated finish - delivers a layer of corrosion resistance, helping the anchor hold up in typical concrete fastening environments
• Sized for medium- and heavy-duty applications - the 5/8 in. diameter and 4-3/4 in. length provide the embedment depth needed for substantial load demands in concrete and masonry work
• Consistent hole sizing is critical - using the correct 5/8 in. drill bit and avoiding oversized holes preserves the anchor's full load capacity and ensures proper setting

Why This Product

• All-in-one hardware design - the integrated nut and washer eliminate the need to source or manage separate fastening components, making the anchor ready to install straight out of the package
• Versatile base material compatibility - engineered to perform in poured concrete, CMU, and brick, this anchor covers a wide range of concrete and masonry fastening scenarios without switching products
• Trusted Simpson engineering for demanding loads - designed specifically for medium- and heavy-duty fastening, the expansion anchor increases the overall strength of masonry connections where structural reliability matters
• Straightforward installation process - the pin-drive setting method paired with a standard 15/16 in. wrench means less specialized tooling is required, helping crews work efficiently on concrete anchoring tasks
