CONFAST 3/8 in x 6-1/2 in Stainless Steel Wedge Anchor - Durable Wet

In this review of the CONFAST 3/8 in x 6-1/2 in Stainless Steel Wedge Anchor, the bottom line is simple: this anchor is for installers and DIYers who need reliable concrete fasteners that resist corrosion in wet or submerged environments. The reviewer found the anchors deliver on durability and ease of installation, making them a solid choice for mounting equipment to concrete where long-term exposure to moisture is expected. The box of five arrives with nuts and washers, which means a fast, complete job without scrambling for hardware.

Key Features

• 304 Stainless Steel Construction: Provides corrosion resistance suitable for wet and submerged environments so installations remain rust-free over time.
• Complete Packaged Hardware: Each anchor comes packaged with nuts and washers so installers can finish a job quickly without buying extra parts.
• Hole Size Matches Anchor Size: Uses a 3/8 in drill bit for simplicity and consistent hole preparation that reduces installation error.
• Thread Length: Four inches of threads allow good adjustment and secure clamping of fixtures to concrete surfaces.
• Wide Range of Sizes Available: Part of a family of wedge anchors so it is easy to match the correct length and diameter for different concrete anchoring needs.

Who It's For

The CONFAST 3/8 in x 6-1/2 in wedge anchor is aimed at contractors, HVAC installers, and homeowners who mount heavy items to poured concrete such as mini-split brackets, railings, or gazebo legs and require corrosion resistance. The included nuts and washers and the straightforward installation make it practical for small crews and single-person jobs.

Those who should look elsewhere include people anchoring into block or brick, or sorting fasteners for materials other than concrete, since this anchor is explicitly designed for concrete only and should not be used in hollow masonry. For very light-duty or temporary fixtures, a smaller or non-stainless fastener might be more economical.
