DeWALT Anchors and Fasteners Screw-Bolt+ Hex Washer Head 1/4 in. x 1-3/4 in. is a one-piece, heavy-duty carbon steel screw anchor engineered for reliable fastening in normal-weight concrete and grouted or solid masonry. With a bright zinc-plated finish for corrosion resistance and a patented thread design that taps directly into the base material, this concrete fastener delivers strong keyed engagement with noticeably lower installation torque than traditional expansion anchors - helping crews work faster and with less effort on demanding jobsite applications.

Key Features

• Patented thread design taps high-strength concrete during installation - creates keyed engagement for a secure, reliable hold without the complexity of separate sleeve anchors
• Designed for standard ANSI tolerance drill bits - no special tooling required, reducing setup time and cost on the jobsite
• Low installation torque in concrete and masonry - reduces operator fatigue and speeds up repetitive fastening tasks
• Ratchet teeth on underside of hex washer head lock against the fixture - prevents loosening and maintains clamping force after installation
• Can be installed closer to a free edge than traditional expansion anchors - allows for greater layout flexibility and more efficient use of concrete surfaces
• Universal product for concrete and grouted or solid masonry - one anchor type covers multiple base material applications, simplifying inventory
• Fully removable design - allows for repositioning or removal of fixtures without destroying the base material
• Bright zinc-plated carbon steel construction - provides corrosion resistance for general-purpose interior and protected exterior concrete anchoring

Why This Product

• The patented thread design works with standard ANSI drill bits rather than proprietary tooling, so installers can start driving anchors immediately without purchasing additional equipment or adapters.
• The ability to install closer to free edges than traditional expansion anchors makes this screw anchor especially practical when working near slab edges, columns, or closely spaced fastening patterns where spacing is tight.
• Because the Screw-Bolt+ is fully removable, it is well-suited for applications where fixtures may need to be adjusted or relocated - a clear advantage over permanent expansion or adhesive anchor systems.
• The one-piece construction simplifies the installation process - there are no separate sleeves, nuts, or washers to manage, which reduces the chance of missing components and helps keep projects moving efficiently.

Frequently Asked Questions

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

The Screw-Bolt+ is suitable for use in normal-weight concrete and grouted or solid masonry. It is a universal anchor for both concrete and masonry base materials, so one product covers a range of common applications.

Can this anchor be removed after installation?

Yes. The Screw-Bolt+ is fully removable, which means fixtures can be repositioned or taken down without destroying the base material - a practical advantage over permanent expansion or adhesive anchor systems.

What size drill bit is needed to install the Screw-Bolt+?

The Screw-Bolt+ is designed for use with standard ANSI tolerance drill bits, so no special or proprietary tooling is required. The patented thread design is specifically engineered to work with these industry-standard bits to minimize installation torque and improve productivity.

How does the hex washer head help secure the fixture?

The underside of the hex washer head features ratchet teeth that lock against the fixture surface during installation. This locking action helps prevent the anchor from loosening over time, maintaining consistent clamping force at the fastening point.
