CONFAST 3/8ft x 5ft Stainless Steel Wedge Anchor - Rustproof Hold

In this review the CONFAST 3/8' x 5' Stainless Steel Wedge Anchor is assessed for installers who need a durable, corrosion resistant fastener for concrete. The bottom line: this anchor is built from 304 stainless steel and designed specifically for wet or submerged concrete applications, so its main selling point is long-term resistance to rust while providing a secure mechanical hold. It comes packaged complete with nuts and washers, and the package size of 50 makes it practical for contractors or weekend projects.

Key Features

• 304 stainless steel construction: Provides reliable corrosion resistance for wet or submerged concrete applications so fastenings last longer.
• Complete hardware in box: Each anchor is packaged with a nut and washer for quick, one-trip installation without searching for matching parts.
• Hole size equals anchor size: The 3/8' anchor requires a 3/8' drill hole, simplifying layout and reducing installation confusion.
• Long thread length: With 3-3/4' of thread, the anchor allows for fine adjustment and strong clamping of fixtures to concrete.
• Designed for concrete only: Optimized geometry and expansion behavior deliver reliable anchoring when used in the correct base material.

Who It's For

The CONFAST wedge anchor is aimed at contractors, HVAC installers mounting mini splits, and homeowners securing structural posts or deck hardware to concrete where a rustproof anchor is required. The 50-per-box count suits jobs that need multiple fastenings or spare anchors for routine maintenance.

Those who should look elsewhere include installers who need anchors for brick, block, or other hollow base materials, since this product is explicitly designed for concrete only. Also, if a smaller quantity or a different alloy is needed, alternative packaging or materials may be a better fit.
