DeWALT Anchors and Fasteners Screw-Bolt+ Hex Washer Head 3/8" x 4" is a heavy-duty, one-piece screw anchor engineered for secure fastening into concrete and masonry substrates. Featuring a finished hex washer head with ratchet locking teeth and a patented thread design, this concrete screw anchor delivers reliable holding power with reduced installation torque - making it a smart choice for contractors and tradespeople who need a high-performance fastening solution that is also fully removable when project needs change.

Key Features

• Patented thread design for low installation torque - the engineered thread profile reduces the effort required to drive the anchor, improving installation speed and reducing operator fatigue on multi-anchor jobs.
• Designed for standard ANSI tolerance drill bits - no special tooling required, so crews can use standard drill bits already on the job site, cutting down on setup time and tooling costs.
• Tough threads tap directly into high-strength concrete - the steel threads cut into the base material during installation to create keyed engagement, delivering strong mechanical interlock without the need for an expansion mechanism.
• Ratchet teeth on the underside of the hex washer head lock against the fixture - once driven, the head resists loosening and backing out, maintaining clamp force and connection integrity under load.
• Bright zinc-plated finish - provides corrosion resistance suitable for interior and sheltered applications, helping the anchor maintain performance over time in standard construction environments.
• Fully removable after installation - unlike traditional expansion anchors, the Screw-Bolt+ can be extracted and replaced if needed, offering flexibility for temporary fixtures or adjustable installations.
• Allows for reduced edge and spacing distances - the keyed thread engagement gives engineers and installers more flexibility when anchoring close to slab edges or in tighter layouts.

Why This Product

• One-piece design simplifies installation - there are no loose components to manage on the job site. The single-body construction means faster setup and fewer opportunities for installation errors compared to multi-part anchor systems.
• Works across a wide range of base materials - approved for use in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick, making this a versatile anchor for a broad variety of commercial and construction applications.
• Low torque installation boosts productivity - the patented thread geometry is specifically engineered to reduce driving resistance, allowing installers to complete more anchors per shift without sacrificing holding quality.
• Removable and reusable in the same hole - the screw-style engagement means the anchor can be backed out cleanly, which is a clear advantage over torque-controlled expansion anchors when modifications or repositioning are required.

Frequently Asked Questions

What drill bit size is required to install the DeWALT Screw-Bolt+ 3/8" x 4" anchor?

The Screw-Bolt+ is designed for use with standard ANSI tolerance drill bits, so no special or proprietary tooling is needed. A standard 3/8" diameter bit compatible with ANSI tolerances is appropriate for this anchor size.

Can this concrete screw anchor be removed after installation?

Yes. The Screw-Bolt+ is fully removable after installation. Unlike expansion-style anchors that permanently deform the base material, the screw thread engagement allows the anchor to be backed out, which is useful when fixtures need to be adjusted, relocated, or removed.

What base materials is the Screw-Bolt+ 3/8" x 4" approved for?

This anchor is suitable for use in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick - covering a wide range of common commercial and residential construction substrates.

How does the hex washer head design improve installation performance?

The hex washer head features ratchet teeth on its underside that lock against the fixture surface once the anchor is driven. This locking action helps prevent the anchor from backing out under load, maintaining a secure and stable connection without additional hardware.
