DeWALT Anchors and Fasteners Screw-Bolt+ Hex Washer Head 3/4" x 6" is a one-piece, heavy-duty concrete screw anchor engineered for reliable fastening in demanding structural applications. Built with a finished hex washer head and zinc-plated steel construction, this screw anchor delivers strong, secure holding power in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick. Designed for professionals who need a fast-installing, fully removable anchor solution, the Screw-Bolt+ combines a patented low-torque thread profile with tough threads capable of tapping directly into high-strength concrete - making it a dependable choice for commercial and industrial fastening projects alike.

Key Features

• Designed for standard ANSI tolerance drill bits - no special tooling required, so you can use the drill bits already on hand and keep installation straightforward and cost-effective.
• Patented thread design offers low installation torque - reduced torque means faster driving with less strain on the installer and improved productivity across large jobs.
• Tough threads for tapping high-strength concrete - the threads cut directly into the base material during installation, creating keyed mechanical engagement for strong, reliable holding power without an expansion mechanism.
• Ratchet teeth on underside of hex washer head lock against the fixture - helps prevent back-out under vibration or dynamic loading, maintaining clamp force once the anchor is set.
• Bright zinc-plated finish - provides a corrosion-resistant surface treatment suited to a variety of indoor and protected structural applications.
• Fully removable one-piece design - simplifies adjustments or repositioning in the field without damaging the base material, saving time on complex installations.
• Allows for reduced edge and spacing distances - the keyed thread engagement means anchors can be positioned closer to edges than traditional expansion anchors, giving installers greater layout flexibility.

Why This Product

• Versatile base material compatibility - suitable for normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick, making this a single anchor solution across multiple substrate types on a job site.
• Engineered for installation speed - the patented low-torque thread profile reduces the physical effort required per anchor and allows crews to complete more installations in less time, supporting higher productivity on large-scale concrete fastening work.
• No special drill bits needed - compatibility with standard ANSI tolerance drill bits lowers the cost of entry and eliminates the need to carry specialty tooling, keeping job-site setups simple.
• Removable and reusable placement - unlike traditional one-way expansion anchors, the Screw-Bolt+ can be fully removed after installation, which is valuable in applications where fixtures may need to be repositioned or updated over time.

Frequently Asked Questions

What drill bit size and type does the DeWALT Screw-Bolt+ 3/4" x 6" require for installation?

The Screw-Bolt+ is specifically designed for use with standard ANSI tolerance drill bits, so no specialty or proprietary bits are needed. This means installers can use common carbide-tipped masonry bits already available on the job site.

Can the Screw-Bolt+ anchor be removed after it has been installed in concrete?

Yes. The Screw-Bolt+ features a fully removable, one-piece design. Once the anchor is installed, it can be backed out of the base material, which is useful when fixtures need to be repositioned or when project requirements change.

What base materials are approved for use with this anchor?

The Screw-Bolt+ 3/4" x 6" is suitable for use in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick. It is not intended for soft or hollow base materials.

How does the ratchet tooth feature on the hex washer head benefit the installation?

The ratchet teeth located on the underside of the hex washer head engage against the fixture surface once the anchor is driven to full seating depth. This helps lock the anchor in place and resist back-out caused by vibration or dynamic loading, helping maintain consistent clamp force over time.
