CONFAST 3/16 in x 2-3/4 in Concrete Screws with Bit - Durable Anchor

In this review the CONFAST 3/16 in x 2-3/4 in concrete screws are evaluated for contractors, DIYers, and anyone fastening to masonry. The bottom line: these screws stand out because each box includes the correct carbide-tipped concrete drill bit, which simplifies installation and maintains holding values compared with buying bits separately. The review focuses on practical performance in concrete, block, and brick, covering drivability, corrosion resistance, and the convenience of a self-tapping design with a flat countersunk head.

Key Features

• Bit included: Each box contains a 5/32 in carbide-tipped bit so installers can drill the correct hole without an extra purchase, saving time on site.
• 410 stainless steel: The screw body is made from 410 stainless steel with a silver Climaseal coating, offering basic corrosion resistance for moist environments.
• Self-tapping thread: The screw taps its own threads into concrete, block, or brick, eliminating the need for a separate anchor and simplifying fastenings.
• Diamond point: The diamond point makes it easier to drive the screw into the predrilled hole, reducing driving time and effort.
• Flat countersunk Phillips head: The head sits flush when installed, keeping the fastened item neat and minimizing protrusion above the surface.
• Hex driver compatible: Although Phillips is specified, the head can be driven with a hex driver for added torque when needed.

Who It's For

These concrete screws are best for builders, handymen, and homeowners who need reliable anchoring into concrete, block, or brick and value the convenience of a box that includes the correct drill bit. The product suits medium-duty applications such as securing metal straps, fixtures, or light structural attachments where a flush countersunk finish is desired.

People who need heavy structural anchoring for load-bearing installations or who require high-grade marine corrosion resistance should look elsewhere and consider anchors and fasteners specified for those extreme conditions.

Pros & Cons

Pros

• Includes the correct 5/32 in carbide-tipped bit, delivering consistent hole diameter and improved holding values.
• Self-tapping design removes the need for a separate anchor, speeding up installation.
• Flat countersunk head provides a clean, flush finish on secured materials.
• Diamond point and hex driver compatibility make driving easier and more flexible by tool choice.

Cons

• 410 stainless steel with Climaseal offers basic corrosion resistance but is not rated for severe saltwater or long-term marine exposure.
