CONFAST 5/8 in x 5 in Wedge Anchor Zinc Plated - Concrete Fastener

In this review the CONFAST 5/8 in x 5 in Wedge Anchor Zinc Plated (Box of 20) is assessed as a straightforward, heavy-duty concrete fastener for installers and fabricators who need reliable hold in dry concrete. The single biggest reason to buy is dependable anchoring performance combined with a complete installation package, since each anchor comes packaged with nuts and washers and the anchor requires only a 5/8 in hole drilled with a carbide tipped bit. This review focuses on real use cases, ease of installation, and material suitability.

Key Features

• Zinc plated finish: Helps prevent rust in dry environments so anchors maintain appearance and function where moisture is not present.
• Complete hardware: Packaged with nuts and washers for fast, quick, and complete installation without needing to source additional parts.
• Hole size equals anchor size: Simplifies drilling and reduces installation errors because the hole diameter is the same as the anchor diameter, 5/8 in.
• Designed for concrete: Made from carbon steel and intended exclusively for concrete substrates to deliver the specified holding strength.
• Long thread reach: With 3 in of thread length, it accommodates a variety of fixture thicknesses and ensures secure clamping.

Who It's For

The CONFAST wedge anchors are best for contractors, mechanics, and shop owners who need strong, repeatable anchor performance in poured concrete for equipment like lifts, posts, or heavy racks. The box of 20 suits jobs that require multiple fixings and reduces trips for extra hardware because nuts and washers are included.

Those working in moist or corrosive environments should look elsewhere or choose a stainless option, as zinc plating is intended for dry environments. Also, do not use this anchor in block or brick; it is specifically designed for concrete only.

Pros & Cons

Pros

• Well-made carbon steel construction with zinc plating provides decent corrosion resistance for dry sites.
• Includes nuts and washers so each anchor is ready to install out of the box.
• Strong holding ability in concrete; customers report successful use on lifts and heavy equipment foundations.
• Simple installation because the hole diameter equals the anchor diameter, reducing measurement guesswork.

Cons

• Not suitable for block or brick applications; limited to concrete only.
• Some users report occasional wedges not gripping fully, so careful installation and inspection are recommended.
