DeWALT Anchors and Fasteners Screw-Bolt+ Hex Washer Head Screw Anchor - 1/2 in. x 3 in. is a one-piece, heavy-duty carbon steel screw anchor engineered for reliable fastening into concrete and masonry substrates. Finished with a bright zinc plating for corrosion resistance, this screw anchor delivers straightforward installation, clear visual identification, and the ability to be fully removed after installation - making it a trusted choice for structural and general construction anchoring tasks. The patented thread design works with standard ANSI tolerance drill bits, reducing installation torque and boosting jobsite productivity whether you are anchoring into normal-weight concrete, concrete over steel deck, or solid clay brick.

Key Features

• Designed for standard ANSI tolerance drill bits - no special or proprietary tooling required, so crews can get to work immediately with equipment already on hand
• Patented thread design offers low installation torque - reduces fatigue and speeds up anchoring tasks across large projects, enhancing overall productivity
• Tough threads tap into high-strength concrete during installation - creates a keyed engagement with the base material, providing secure, reliable hold and allowing for reduced edge and spacing distances
• Ratchet teeth on the underside of the hex washer head lock against the fixture - prevents loosening under load or vibration, maintaining a secure connection over time
• One-piece, finished hex washer head construction - simplifies installation with a single component and makes the anchor easy to identify in the field
• Fully removable after installation - allows repositioning or disassembly without damaging the base material, offering flexibility during and after construction
• Bright zinc-plated carbon steel finish - provides a corrosion-resistant coating suited for interior concrete and masonry anchoring applications
• 1/2 in. diameter x 3 in. fastener length - delivers the embedment depth needed for heavy-duty anchoring in a wide range of structural applications

Why This Product

• The patented low-torque thread design means faster, easier installations compared to anchors that demand high-torque tooling - a direct productivity advantage on large concrete anchoring jobs
• Full removability sets this screw anchor apart for applications where adjustments or disassembly are anticipated - no need to core out or damage the base material to reposition
• Compatibility with normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick makes this a single anchor solution for multiple common base materials on a typical job site
• The ratchet teeth integrated into the hex washer head provide a self-locking fixture connection, reducing the risk of anchor back-out in demanding load conditions

Frequently Asked Questions

What drill bit size and type is required to install the Screw-Bolt+ 1/2 in. x 3 in. anchor?

The Screw-Bolt+ is designed for use with standard ANSI tolerance drill bits, so no specialty or proprietary bits are needed. Using a standard 1/2 in. ANSI-compliant bit ensures the patented thread design engages correctly for optimal holding performance and reduced installation torque.

Can this anchor be removed after it has been installed in concrete?

Yes. The Screw-Bolt+ is fully removable after installation. This makes it a practical choice for applications where future disassembly, repositioning, or temporary fastening is a possibility, without requiring destructive removal techniques.

What base materials is the 1/2 in. x 3 in. Screw-Bolt+ rated for?

Suitable base materials include normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick - covering a wide range of common structural substrates found in commercial and residential construction.

What is the purpose of the ratchet teeth on the underside of the hex washer head?

The ratchet teeth on the underside of the hex washer head are designed to lock against the fixture during installation. This feature helps prevent the anchor from backing out under load or vibration, maintaining a secure and stable connection throughout the life of the installation.
