3/8 in x 2-1/4 in Stainless Steel Wedge Anchor Pack of 10 - Corrosion

In this review the CONFAST 3/8' x 2-1/4' Stainless Steel Wedge Anchor (10 per Box) is presented as a practical choice for contractors, DIYers and anyone mounting fixtures to concrete. The bottom line: this anchor is for projects where long-term corrosion resistance and straightforward installation matter. It is made from 304 stainless steel so it performs in wet or submerged environments, and it arrives packaged with nuts and washers to make a fast, complete installation without hunting for compatible hardware.

Key Features

• 304 Stainless Steel: Provides corrosion resistance for wet and submerged environments so anchors do not rust over time.
• Complete Hardware: Packaged with nuts and washers so installations are faster and you do not need extra parts.
• Hole Size Matches Anchor: A 3/8' hole diameter simplifies drilling steps and reduces sizing mistakes during installation.
• Designed for Concrete: Engineered specifically for use in concrete, giving reliable anchoring when installed to the specified embedment depth.
• Wide Range of Sizes: The availability of this size in a standard lineup helps ensure proper fastener selection for different loads and fixtures.

Who It's For

This anchor is best suited for professionals and homeowners mounting heavy items to concrete such as HVAC brackets, gazebos, railings or machinery bases where resistance to moisture and salt is required. Installers who value speed will appreciate the included nuts and washers and the simplified hole-sizing rule.

It is not intended for use in block or brick base materials, so those attaching to masonry other than concrete should look for anchors rated for hollow or grout-filled block. Also, projects requiring anchors longer than 2-1/4' or different embedment depths will need a different size from the same family.

Pros & Cons
