CONFAST 3/8ft x 3-3/4ft Stainless Steel Wedge Anchor - Corrosion

In this review of the CONFAST 3/8' x 3-3/4' Stainless Steel Wedge Anchor, the bottom line is simple: this is a workmanlike concrete anchor for installers and DIYers who need reliable corrosion resistance in wet or submerged environments. The reviewer found these anchors useful where stainless performance matters most, and the inclusion of nuts and washers makes installations faster and more complete. For anyone mounting heavy items to concrete and seeking long-term durability, this box of 50 offers consistent specifications and straightforward installation.

Key Features

• 304 Stainless Steel Construction: Provides excellent resistance to rust in wet and submerged conditions so fastened assemblies stay reliable over time.
• Packaged with Nuts and Washers: Each anchor comes ready for a complete installation which saves time and avoids searching for hardware during a job.
• Hole Size Matches Anchor Size: The simple 3/8' hole requirement reduces confusion and speeds drilling by specifying the bit diameter equal to the anchor diameter.
• Wide Range of Sizes: Available sizing choices help ensure the correct fastener for the specific concrete application and load needs.
• Designed for Concrete Only: Engineered specifically for use in concrete to deliver dependable anchoring where base material is solid slab.

Who It's For

These wedge anchors are best for contractors, HVAC technicians, and homeowners who attach equipment, frames, or structures directly to concrete and need corrosion-resistant anchors for outdoor, wet, or submerged installations. The 50-per-box quantity suits medium to large jobs, like mounting mini split brackets, railings, or gazebo legs to concrete decks.

Those working with hollow block, brick, or other nonconcrete base material should look for anchors designed for those substrates. If a finished exterior appearance or decorative anchor head is required, a different style may be preferable.
