DeWALT Anchors and Fasteners Screw-Bolt+ Hex Washer Head 1/2" x 2-1/2" is a heavy-duty, one-piece screw anchor engineered for reliable fastening in normal-weight concrete and grouted or solid masonry applications. Featuring a patented thread design and a zinc-plated carbon steel construction, this concrete screw anchor delivers low installation torque, simplified removal, and strong keyed engagement - making it a practical choice for contractors and builders who need a dependable, code-friendly fastening solution in structural concrete work.

Key Features

• Designed for standard ANSI tolerance drill bits - no special tooling required, which reduces setup time and keeps installation straightforward on the job site.
• Patented thread design offers toughened threads for tapping high-strength concrete - the threads cut directly into the base material for a secure, keyed mechanical connection.
• Low installation torque in concrete and masonry - reduces installer fatigue and speeds up productivity compared to traditional expansion anchors.
• Universal product for concrete and grouted or solid masonry - one anchor type covers a wide range of common base materials, simplifying inventory management.
• Ratchet teeth on the underside of the hex washer head lock against the fixture - keeps the anchor from backing out under load and provides a more secure, stable connection.
• Can be installed closer to a free edge than traditional expansion anchors - allows placement in tighter locations near slab edges, corners, and openings where other anchors may not qualify.
• Fully removable one-piece design - the anchor can be backed out cleanly after installation, which is useful when fixtures need to be repositioned or replaced.
• Bright zinc-plated carbon steel finish - provides a protective coating suitable for general interior concrete fastening applications.

Why This Product

• The patented thread geometry taps into concrete during installation, creating keyed engagement without the need for a sleeve or clip - eliminating extra components and reducing the chance of installation errors.
• Reduced edge and spacing distance requirements mean this anchor can be used in constrained locations where traditional expansion anchors fall short, giving installers more flexibility in concrete fastening layouts.
• The hex washer head with ratchet teeth on the underside locks against the fixture during tightening, delivering a more positive hold that resists loosening without additional hardware.
• A fully removable design makes this concrete screw anchor reusable in temporary fixture applications, helping reduce material waste and re-work costs on the job site.

Frequently Asked Questions

What base materials is the Screw-Bolt+ rated for?

According to the product data, the Screw-Bolt+ is suitable for normal-weight concrete and grouted or solid masonry. It is a universal anchor designed to perform across these common base materials without requiring a separate anchor type for each.

Does the Screw-Bolt+ require any special drill bits for installation?

No. The Screw-Bolt+ is specifically designed for use with standard ANSI tolerance drill bits. No proprietary or specialty tooling is required, which simplifies setup and keeps installation costs down on the job site.

Can this anchor be removed after installation?

Yes. The Screw-Bolt+ is a fully removable anchor. Because the threads tap into the base material mechanically, the anchor can be backed out after installation - a practical advantage when fixture locations need to be adjusted or when temporary connections are needed.

How does the hex washer head design help secure the fixture?

The hex washer head features ratchet teeth on its underside that lock directly against the fixture surface as the anchor is tightened. This locking action resists the anchor from backing out under load, providing a more positive and stable hold without additional locking hardware.
