CONFAST 3/8 in x 2-3/4 in Galvanized Wedge Anchor (Box of 50)

In this review of the CONFAST 3/8 in x 2-3/4 in Galvanized Wedge Anchor, the bottom line is simple: this boxed set is aimed at contractors, fabricators, and serious DIYers who need reliable concrete anchors that resist corrosion and install quickly. The reviewer found the anchors deliver consistent performance for concrete-only applications, with the galvanized finish providing clear protection in damp environments and the inclusion of nuts and washers saving installation time. For anyone mounting treated lumber, steel brackets, or structural components to concrete, these anchors represent a practical, value-oriented choice.

Key Features

• Galvanized finish: Helps prevent rusting in moist environments so installed anchors maintain appearance and function longer.
• Packaged complete: Comes with nuts and washers to allow fast, complete installations without separate hardware purchases.
• Hole size equals anchor size: Simplicity of a 3/8 in hole requirement reduces installation errors and tool guesswork.
• Designed for concrete: Carbon-steel construction and wedge design deliver firm holding power when used in concrete base material only.
• Thread length: 1-1/2 in of threads provides adequate engagement for common attachments while leaving proper embedment depth.

Who It's For

These anchors suit professional builders, contractors, and experienced homeowners who fasten medium-duty loads to concrete surfaces, such as attaching treated lumber, steel plates, or quonset hut walls. The box of 50 and included washers and nuts make it efficient for larger projects where speed and consistency matter.

Those who need anchors for block, brick, or hollow base materials should look elsewhere, because these wedge anchors are intended strictly for concrete. Also, projects requiring stainless steel corrosion resistance in highly corrosive or marine environments will require a different fastener type.

Pros & Cons

Pros

• Good value for a box of 50, with hardware included so projects move faster.
• Galvanized coating adds corrosion resistance for damp environments and outdoor work.
• Clear installation spec where the hole diameter equals the anchor diameter simplifies drilling and reduces mistakes.
• Robust carbon-steel construction provides dependable anchor strength for concrete applications.

Cons

• Limited to concrete base material and not suitable for block or brick, which restricts some applications.
• Galvanized coating is protective but not equivalent to stainless steel in extreme marine conditions.

Frequently Asked Questions

Can these anchors be used in brick or block?
No. These wedge anchors are designed for use in concrete only and should not be used in block or brick base material.

What drill bit should I use?
Use a 3/8 in carbide-tipped bit in a hammer drill that meets ANSI standards to create the required hole diameter.

Is the finish suitable for outdoor use?
The galvanized finish is suitable for damp and outdoor environments, but it is not a substitute for stainless steel in highly corrosive or marine conditions.
