10 Best Concrete Screws 2026 in the United States

The Red Head SLDT-3830 is a stainless steel concrete screw designed for heavy-duty fastening in concrete. Its 3/8-inch diameter and 3-inch length make it suitable for medium to large anchoring jobs, providing good holding strength. Made from stainless steel 410 with an anti-corrosion topcoat, this screw is resistant to rust, which is important if you plan to use it in outdoor or damp environments.

The flanged hex washer head with anti-rotation serrations ensures a secure grip during installation, and the external hex drive system is compatible with standard hex bits, making it easy to install with common tools. The screw cuts its own threads into concrete, which means you don’t need special anchors or inserts, just a standard drill bit of the right size. It’s fully threaded with a coarse UNC thread style, giving firm grip in the concrete material.

Weighing 4.7 pounds per box of 50, it is somewhat heavier than some alternatives, which might be a consideration if you’re handling many boxes or transporting them. The product has an average user rating of 4.3, indicating reliable performance in typical concrete fastening tasks. This makes it a good choice for contractors or DIY users needing durable, corrosion-resistant screws for concrete, especially when a strong, threaded anchor is needed without extra hardware.

The Simpson Strong-Tie THDB62800H is a heavy-duty concrete screw anchor measuring 5/8 inch in diameter and 8 inches in length, making it suitable for securing sill plates, ledgers, and post bases in both cracked and uncracked concrete or masonry. Its hex washer head offers a clean look and eliminates the need for a separate washer, which simplifies installation. The screw’s thread design is optimized to grip the concrete deeply, helping to transfer loads effectively and enhance holding strength. Made from carbon steel with a zinc-plated coating, it provides decent corrosion resistance for dry, indoor environments, although it may not be ideal for outdoor or highly humid conditions.

Installation is straightforward since it can be used with standard drill bits, meaning no special tools are required. The zinc plating is good for corrosion resistance indoors, but users needing outdoor durability might want to consider anchors with more robust coatings. This product represents a reliable choice for general heavy-duty concrete anchoring tasks where ease of installation and strong hold are important.

The ITW Brands Tapcon Hex Washer Head Concrete Anchors are a solid choice if you need reliable screws for fastening into concrete, brick, or block. These screws measure 1/4 inch in diameter and 6 inches in length, which is a versatile size suitable for many common projects like securing sill plates or electrical fixtures. Made from alloy steel with a blue Climaseal coating, they offer good protection against rust and corrosion, making them a durable option for outdoor or damp environments. The hex washer head design gives you a strong grip with a wrench or drill, which is helpful for driving screws securely.

What stands out is the advanced threadform technology combined with chisel-edged threads that cut into masonry easily, reducing the effort needed to install them by about 30%. This means you can expect more consistent and less tiring fastening, even in tough materials. Being fully threaded ensures a firm hold along the entire length of the screw. On the downside, these screws are a bit specialized, so they require a compatible drill bit (included) and a hex driver for best results—standard screwdriver bits won’t work. Also, while they work well for medium-duty tasks, if you have extremely heavy loads or very soft masonry, you might need a different type of anchor.

In summary, these concrete screws provide a dependable, corrosion-resistant option for DIYers and professionals needing an efficient, strong fastener for masonry projects.
