DeWALT Anchors and Fasteners Screw-Bolt+ Hex Washer Head 1/2" x 8" Screw Anchor is a one-piece, heavy-duty concrete screw anchor engineered for fast, reliable fastening into a wide range of masonry base materials. With a finished hex washer head, bright zinc-plated finish, and a patented thread design that works with standard ANSI tolerance drill bits, this 1/2" diameter anchor simplifies installation while delivering strong, keyed engagement in concrete and masonry applications. Fully removable after installation, it is an ideal choice for contractors and tradespeople who need dependable performance without the complexity of multi-component anchor systems.

Key Features

• Patented thread design offers low installation torque - reduces the effort and time required to drive the anchor, improving jobsite productivity and reducing operator fatigue during high-volume installations.
• Designed for standard ANSI tolerance drill bits - eliminates the need for specialty tooling, so installers can use drill bits already on hand and stay productive without extra equipment costs.
• Tough threads tap into high-strength concrete during installation - threads along the anchor body cut directly into the base material to create keyed engagement, allowing for reduced edge and spacing distances in concrete and masonry.
• Ratchet teeth on underside of hex washer head lock against the fixture - provide a secure, vibration-resistant connection that maintains clamp force once the anchor is fully driven.
• Bright zinc-plated finish - provides a corrosion-resistant silver surface that is easy to identify on the jobsite and suitable for interior and protected concrete applications.
• Fully removable one-piece design - allows the anchor to be backed out and repositioned if needed, offering flexibility that permanent anchors cannot provide.

Why This Product

• Simplified installation into multiple masonry types - approved for use in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick, making this a single anchor solution for many common construction substrates.
• Works with your existing drill bits - the ANSI-compatible design means no special drill bits or proprietary tools are required, reducing setup time and keeping tool costs down on the job.
• Low torque installation without sacrificing holding strength - the patented thread profile cuts into the base material efficiently, so installers can work faster without compromising the integrity of the connection.
• Removable and reusable design reduces waste and rework costs - unlike adhesive or expansion anchors that are permanent once set, this screw anchor can be removed and reinstalled, which is especially valuable during fixture adjustments or phased construction.

Frequently Asked Questions

What drill bit size is required to install this anchor?

This anchor is designed for use with standard ANSI tolerance drill bits in the 1/2" diameter size, so no specialty or proprietary drill bits are needed for installation.

Can this screw anchor be removed after installation?

Yes. The Screw-Bolt+ is a fully removable anchor. It can be backed out of the base material after installation, which allows for fixture adjustments or removal without damaging the surrounding concrete or masonry.

What base materials is this anchor suitable for?

This anchor is approved for use in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick.

What does the ratchet teeth feature on the hex washer head do?

The ratchet teeth on the underside of the hex washer head lock against the fixture surface during installation, helping to maintain clamp force and resist loosening from vibration once the anchor is fully driven.
