CONFAST 3/4 in x 7 in Wedge Anchor Zinc Plated (Box of 10) - Durable

In this review the CONFAST 3/4 in x 7 in Wedge Anchor is evaluated as a straightforward, heavy-duty concrete fastener for tradespeople and DIYers who need reliable hold in dry concrete. The bottom line: it is best for anchoring equipment and structures where a long, zinc plated steel anchor with included nuts and washers simplifies installation and resists corrosion in non-wet environments. The reviewer found the anchors robust, easy to install when the correct 3/4 in carbide bit and hammer drill are used, and particularly well suited to applications that demand substantial embedment and thread length.

Key Features

• Zinc plated construction: provides basic corrosion resistance for use in a dry environment so anchors remain serviceable over time.
• Packaged with nuts and washers: enables a complete installation out of the box without hunting for matching hardware, speeding assembly.
• Hole size equals anchor size: using a 3/4 in hole simplifies layout and drill bit selection for consistent installations.
• Long thread length: 4 in of threads gives flexibility to clamp varying fixture thicknesses while maintaining sufficient embedment.
• Designed for concrete only: ensures optimum performance when set into solid concrete and avoids misuse in unsuitable masonry like block or brick.
• Wide range of sizes: part of a family of anchors so you can select the correct diameter and length for different load needs.

Who It's For

The CONFAST wedge anchor is ideal for mechanics, contractors, and workshop owners who need to secure lifts, machinery, posts, or structural components to poured concrete. Its 7 in length and minimum embedment requirement make it suited to medium to heavy anchoring tasks where a deep, reliable hold is required.

It is not the right choice for use in hollow block, brick, or damp/outdoor marine environments where stainless or specially coated anchors are preferable. Homeowners who only need lightweight fastenings or who lack a hammer drill and the correct 3/4 in carbide bit may want to consider simpler concrete screws or smaller anchors.

Pros & Cons

Pros

• Well made carbon steel body with zinc plating gives good value for money for dry installations.
• Includes nuts and washers for quick, complete assembly and fewer missing parts on the jobsite.
• Long 4 in thread and 7 in overall length provide flexibility for thicker fixtures and strong embedment.
• Consistent sizing rule (hole diameter equals anchor diameter) simplifies drilling and reduces installation errors.

Cons

• Zinc plating is suitable only for dry environments and may not tolerate prolonged outdoor or wet exposure as well as stainless options.
• A small number of customers reported the wedge sometimes not gripping properly, so careful installation technique is required.
