CONFAST 3/4ft x 10ft Stainless Steel Wedge Anchor - Durable Wet Use

Our review of the CONFAST 3/4' x 10' Stainless Steel Wedge Anchor finds it most useful for contractors, HVAC installers and homeowners who need a corrosion-resistant anchor for concrete in wet or submerged environments. The main reason to buy is the use of 304 stainless steel, which delivers long-term resistance to rust where carbon steel anchors would fail; reviewers repeatedly praised the stainless steel quality and anchoring ability. This is a straightforward concrete-only anchor supplied with nuts and washers for a complete installation.

Key Features

• 304 Stainless Steel Construction: Offers reliable corrosion resistance so the anchor can be used in wet or submerged environments without rusting.
• Correct Hole Size: Uses a 3/4' hole equal to the anchor diameter, simplifying layout and ensuring a consistent fit when drilled with the recommended carbide bit.
• Packaged Complete: Comes with nuts and washers so installers have everything needed for a fast, complete installation on arrival.
• Ample Thread Length: Provides 4' of threads, giving flexibility for different fixture thicknesses and secure fastening to concrete.
• Minimum Embedment: Designed for a minimum embedment of 3-1/4', which ensures proper expansion and holding power when installed correctly.

Who It's For

This anchor is best for professionals and serious DIYers who need a dependable stainless solution for concrete applications exposed to moisture, such as mounting mini split condensers, securing gazebo posts to concrete decks, or marine-side installations. The inclusion of nuts and washers makes it convenient for job sites where speed matters.

It is not suitable for use in block or brick base material, so those working with masonry other than solid concrete should look for anchors rated for hollow or brick substrates. If you need a different diameter or a non-stainless option for interior dry work, other fasteners may be more economical.

Pros & Cons
