CONFAST 1/2 in x 7 in Stainless Steel Wedge Anchor (5 per Box)

In this review the CONFAST 1/2 in x 7 in Stainless Steel Wedge Anchor is assessed for contractors and DIYers who need reliable concrete fasteners for wet environments. The bottom line: it is a straightforward, heavy duty wedge anchor made from 304 stainless steel that will not rust when used in submerged or damp conditions, and it ships complete with nuts and washers so installations are fast and predictable. The review focuses on build quality, installation simplicity, and where this anchor fits in typical mounting tasks.

Key Features

• 304 Stainless Steel Construction: Provides corrosion resistance for wet and submerged installations so the anchor maintains strength over time.
• Packaged Complete: Each anchor comes with a nut and washer which makes for a fast, complete installation without hunting for hardware.
• Hole Size Matches Anchor Size: Requiring a 1/2 in drill bit simplifies preparation and reduces the chance of drilling the wrong diameter hole.
• Thread Length: The 4 in of thread gives flexibility in how much material the anchor can clamp while still meeting embedment requirements.
• Designed for Concrete: Engineered specifically for concrete base material, delivering consistent performance when installed to the correct embedment depth.

Who It's For

The CONFAST wedge anchor is best for builders, HVAC technicians, and homeowners who need a robust fastener for mounting equipment to concrete, such as mini splits, railings, or gazebo anchors on concrete decks. Its 304 stainless construction suits coastal or other wet sites where ordinary steel would corrode.

Those working with block, brick, or hollow base materials should look at anchors designed for those substrates, because this wedge anchor is intended for concrete only and must be installed with a hammer drill and the correct carbide bit.
