CONFAST 1/4 in x 1-3/4 in Concrete Screws - Bit Included for Masonry

In this review the CONFAST 1/4 in x 1-3/4 in concrete screws are evaluated for tradespeople and DIYers who need a reliable direct-to-masonry fastener. The single biggest reason to consider these screws is convenience: each 50-box includes a carbide-tipped drill bit matched to the required 3/16 in hole, which reduces trips for extra tools and helps achieve the correct hold in concrete, block, and brick. The review focuses on durability, ease of install, and whether the screws deliver consistent anchoring in damp environments.

Key Features

• Bit included: Each box ships with a carbide-tipped drill bit to create the specified 3/16 in hole so installers get the correct pilot size without guesswork.
• 410 stainless steel: The screws are made from 410 stainless steel with a silver Climaseal coating to resist corrosion in moist environments.
• Self-tapping design: The threads tap directly into masonry, eliminating the need for an additional anchor and speeding installation.
• Diamond point: The pointed tip makes initial driving easier and reduces time spent starting each screw.
• Flat countersunk head: The Phillips flat head sits flush after installation to keep the fastened material smooth and unobtrusive.
• Multiple driver options: While a #3 Phillips is specified, the screws can also be driven with a hex driver for extra torque when needed.

Who It's For

These concrete screws are best for contractors, maintenance crews, and experienced DIYers who frequently anchor fixtures to concrete, block, or brick and want a complete solution in one box. The included carbide bit and self-tapping threads make them especially useful on jobs where speed and consistent hole size matter.

Those who should look elsewhere include users needing stainless grades with higher corrosion resistance for marine or highly corrosive settings, or anyone requiring very long lengths; this product is a 1-3/4 in length and is optimized for typical interior and sheltered exterior masonry work.

Pros & Cons

Pros

• Bit included saves time and ensures the correct 3/16 in pilot hole for reliable holding.
• 410 stainless steel with Climaseal coating provides basic corrosion resistance for moist environments.
• Self-tapping thread and diamond point reduce installation steps and effort.
• Flat countersunk head yields a neat, flush finish on installations.

Cons

• 410 stainless offers moderate corrosion resistance but is not as durable as higher stainless grades in harsh coastal conditions.
• Length is fixed at 1-3/4 in, so longer anchoring needs require a different product.

Our Verdict

The CONFAST 1/4 in x 1-3/4 in concrete screws are a sensible choice for installers who value a ready-to-use box with a matched drill bit and a self-tapping design that speeds work on concrete, block, and brick. For typical interior or sheltered exterior masonry anchoring these screws deliver good value and consistent performance, though users in highly corrosive environments should choose a higher stainless grade.

Frequently Asked Questions

What drill bit size is required?
The screws require a 3/16 in hole and each box includes a carbide-tipped bit suited to that diameter.

Can these be used outdoors?
Yes, they are coated and made from 410 stainless steel for use in moist environments, but not ideal for severe marine exposure.

What driver is needed?
A #3 Phillips driver is specified, and the screws can also be driven with a hex driver for higher torque.
