CONFAST 3/4 in x 5-1/2 in Wedge Anchor Zinc Plated - Concrete

In this review of the CONFAST 3/4 in x 5-1/2 in Wedge Anchor Zinc Plated (Box of 20), the bottom line is simple: this is a practical, heavy-duty concrete anchor for installers who need reliable hold and quick installation in dry environments. The reviewer found these anchors best for concrete applications where corrosion risk is moderate and a complete kit (anchor, nut and washer) speeds jobsite work. The anchors are designed for a 3/4 in hole and deliver straightforward installation and predictable embedment, making them a good choice for structural and equipment anchoring where concrete is the only base material.

Key Features

• Zinc plated: Provides basic corrosion resistance to help prevent rust in dry environments so anchors remain serviceable for longer when not exposed to moisture.
• Packaged with nuts and washers: Each box includes the hardware needed for a complete installation, saving time and trips to the parts bin.
• Hole size equals anchor size: Using a 3/4 in drill bit simplifies layout and ensures the correct fit without complex sizing calculations.
• Designed for concrete only: The wedge mechanism and carbon steel construction are optimized for solid concrete, so performance is most reliable in that substrate.
• Wide range of sizes: The availability of multiple lengths and diameters helps match the correct fastener to the job for better load distribution and safety.

Who It's For

The CONFAST wedge anchor is aimed at contractors, shop mechanics and builders who frequently fasten equipment, posts or heavy fixtures to poured concrete. It is particularly useful when installers want a ready-to-use box with nuts and washers included and need a simple 3/4 in hole drill specification to follow.

Those who should look elsewhere include users who need anchors for brick, block or wet/marine environments, since these anchors are specified for concrete only and for dry conditions; stainless or specialized anchors would be a better choice where corrosion or different substrates are concerns.

Pros & Cons

Pros

• Includes nuts and washers for fast, complete installation without sourcing extra parts.
• Zinc plating offers basic rust resistance suitable for dry interior or sheltered exterior installations.
• Strong wedge design provides secure hold in solid concrete, with customer reports of heavy loads held reliably.
• Simple sizing rule where hole diameter matches anchor diameter reduces installation errors.

Cons

• Not intended for block or brick, limiting use to concrete only.
• Some customers reported occasional wedges not gripping as expected, suggesting attention to drilling and installation technique is required.

Specifications

Our Verdict

The CONFAST 3/4 in x 5-1/2 in Wedge Anchor is a solid, no-nonsense choice for fastening to poured concrete when installers want included nuts and washers and a simple 3/4 in hole specification. It represents good value for jobs in dry environments and for users who need dependable mechanical hold, though those working with masonry block, brick or in corrosive conditions should choose a substrate-appropriate anchor instead.
