DeWALT Anchors and Fasteners Screw-Bolt+ Hex Washer Head 5/8" x 3" Screw Anchor is a one-piece, heavy-duty concrete screw anchor engineered for secure, reliable fastening in normal-weight concrete and grouted or solid masonry applications. From DeWALT ANCHORS AND FASTENERS, this bright zinc-plated anchor combines a patented thread design with ratchet-locking hex washer head geometry to deliver low installation torque, strong keyed engagement, and the flexibility to be fully removed and reinstalled - making it a go-to choice for contractors and structural fastening professionals who need both performance and convenience in concrete anchoring jobs.

Key Features

• Designed for standard ANSI tolerance drill bits - works with the drill bits already in your kit, eliminating the need for special tooling and keeping job-site costs down.
• Patented thread design offers toughened threads for tapping high strength concrete - the threads cut directly into the base material to form a tight keyed engagement, creating a strong mechanical lock without expansion forces.
• Low installation torque in concrete and masonry - reduces operator fatigue and speeds up installation, boosting productivity on large fastening projects.
• Universal product for concrete and grouted/solid masonry - one anchor type covers multiple base materials, simplifying inventory management and reducing the chance of using the wrong anchor for the substrate.
• Ratchet teeth on underside of hex washer head lock against the fixture - the serrated bearing surface grips the fixture positively, preventing loosening under vibration or load cycling.
• Can be installed closer to a free edge than traditional expansion anchors - reduced edge and spacing distance requirements give you more placement flexibility near slab edges, openings, and adjacent anchors.
• Fully removable and reusable - the anchor can be extracted and reinstalled, making it practical for temporary fixtures or applications that require periodic maintenance access.
• Bright zinc-plated steel construction - provides a durable corrosion-resistant finish suited for interior and protected concrete fastening applications.

Why This Product

• Simplified installation with tools you already own - because the Screw-Bolt+ is designed for standard ANSI tolerance drill bits, there is no need to purchase proprietary tooling, which saves time and reduces set-up cost on the job.
• Fewer constraints on anchor placement - the patented steel thread design allows reduced edge and spacing distances compared to traditional expansion anchors, giving structural fastening professionals more layout flexibility in tight or congested concrete sections.
• One anchor for multiple substrates - the universal design is rated for normal-weight concrete and grouted or solid masonry, so a single anchor product can address a wider variety of structural fastening scenarios without switching products mid-project.
• Built-in fixture locking without extra hardware - the ratchet teeth integrated into the underside of the hex washer head lock against the mounted fixture automatically during installation, providing vibration-resistant clamping without additional lock washers or secondary fasteners.

Frequently Asked Questions

What drill bit size is required to install the Screw-Bolt+ 5/8" x 3" anchor?

The Screw-Bolt+ is designed for use with standard ANSI tolerance drill bits. Because it uses a standard ANSI specification, no proprietary or special drill bit is needed - a standard 5/8 in. ANSI-tolerance carbide-tipped bit is compatible with this anchor.

Can this anchor be removed after installation?

Yes. The Screw-Bolt+ is fully removable. The screw-style installation means it can be backed out with a standard wrench or driver after installation, making it suitable for temporary fixtures or applications that require maintenance access.

Why can this anchor be placed closer to edges than traditional expansion anchors?

The patented thread design causes the steel threads along the anchor body to tap directly into the concrete or masonry during installation, creating keyed engagement without the outward expansion forces that traditional wedge or sleeve anchors exert. Because there are no expansion forces pushing against the surrounding material, reduced edge and spacing distances are achievable.

What is the function of the ratchet teeth on the hex washer head?

The ratchet teeth are located on the underside of the hex washer head and bear directly against the surface of the fixture being fastened. As the anchor is tightened, these teeth lock mechanically against the fixture, resisting loosening caused by vibration or dynamic loading without requiring additional lock washers or secondary locking hardware.
