CONFAST 1/2 in x 3-3/4 in Stainless Steel Wedge Anchor - Durable Wet

In this review the CONFAST 1/2 in x 3-3/4 in Stainless Steel Wedge Anchor is examined for those who need a dependable concrete fastener for wet or submerged environments; the single biggest reason to buy is its 304 stainless steel construction, which resists rust where regular anchors would fail. The reviewer found the pack of 25 useful for multiple projects and appreciates that each anchor comes complete with nuts and washers, meaning installations are fast and require no additional parts on site. Practical details like hole size equaling anchor size make the product straightforward to use.

Key Features

• 304 Stainless Steel: Provides corrosion resistance so anchors maintain strength and appearance in wet or submerged environments.
• Complete Hardware Included: Each anchor is packaged with nuts and washers so installations are finished without hunting for extra parts.
• Hole Size Matches Anchor: The 1/2 in anchor requires a 1/2 in hole, simplifying drill bit selection and reducing installation mistakes.
• Thread Length: With 2-1/4 in of threads, the anchor allows ample adjustment for mounting fixtures flush to the surface.
• Minimum Embedment: A 2-1/4 in embedment requirement gives a clear guideline for secure installations in concrete.

Who It's For

This anchor is best for contractors, DIYers, and maintenance crews who mount equipment to concrete in outdoor, coastal, or otherwise wet locations and need stainless performance that will not rust. It is well suited to applications like mounting HVAC equipment, securing gazebos, or anchoring railings where long-term corrosion resistance is important.

Those who should look elsewhere include anyone working in hollow block, brick, or other non-concrete base materials, since the product is designed for concrete only and is not rated for use in masonry units with voids.

Pros & Cons

Pros

• Made from 304 stainless steel for reliable corrosion resistance in wet environments.
• Packaged with nuts and washers so each anchor is ready for immediate installation.

Cons

• Designed strictly for concrete use and should not be used in block or brick base material.
• Requires a hammer drill and ANSI-compliant carbide bit for proper hole drilling, which adds tool requirements for some users.
