The Simpson Easy-Set 5/8 in. x 4 in. Pin-Drive Expansion Anchor from Simpson is a carbon steel mechanical anchor engineered for medium- and heavy-duty fastening applications into concrete base materials, including concrete masonry unit (CMU) and brick. Its pin-drive expansion design locks the anchor firmly in place within the base material, while the integrated nut and washer simplify the installation process and reduce the chance of losing loose hardware on the job site.

Key Features

• Integrated nut and washer - keeps all components together as a single unit, reducing the risk of misplaced parts and speeding up installation.
• Pin-drive expansion mechanism - anchors expand within the base material to form a strong, reliable connection suited for medium- and heavy-duty structural demands.
• Compatible with concrete, CMU, and brick - broad base material compatibility makes this anchor a versatile choice across a range of masonry fastening and structural reinforcement applications.
• Carbon steel construction with Yellow-Zinc Dichromate Plated finish - delivers the strength required for demanding fastening tasks while the plated finish provides a layer of corrosion resistance.
• Precise hole sizing is critical - using the correct 5/8 in. drill bit ensures proper anchor engagement; oversized holes reduce load capacity and make setting the anchor more difficult, so accurate hole preparation directly protects connection integrity.

Why This Product

• Simplified one-piece installation - the integrated nut and washer eliminate the need to manage separate hardware components, making the installation process faster and more efficient on busy job sites.
• Reliable holding power in multiple masonry substrates - engineered to perform in concrete, CMU, and brick, this expansion anchor covers a wide range of structural and masonry fastening scenarios without requiring different anchors for different materials.
• Expansion design built for heavy-duty loads - the pin-drive expansion method creates a mechanical interlock within the base material, providing the holding strength needed for demanding medium- and heavy-duty concrete fastening applications.
• Trusted Simpson engineering - designed by Simpson, a brand recognized for structural fastening and connector products, giving contractors and builders confidence in the anchor's performance for masonry reinforcement and concrete attachment projects.

Frequently Asked Questions

What size drill bit is required to install the EZAC62400 anchor?

The EZAC62400 requires a 5/8 in. drill bit to create the proper hole in the base material for installation.

What base materials is the Easy-Set EZAC anchor compatible with?

The EZAC anchor provides holding power in concrete base materials including both concrete masonry unit (CMU) and brick.

What wrench size is needed to install this anchor?

A 15/16 in. wrench is required to tighten the integrated nut during installation of the EZAC62400 anchor.

Why is it important to avoid oversized holes when installing this anchor?

Oversized holes in the base material will make it difficult to set the anchor and will reduce the anchor's load capacity, compromising the integrity of the connection.
