DeWALT Screw-Bolt+ Hex Washer Head 3/8 in. x 2-1/2 in. by DeWALT ANCHORS & FASTENERS is a heavy-duty, one-piece screw anchor engineered for reliable fastening in normal-weight concrete and grouted or solid masonry. The zinc-plated carbon steel construction delivers corrosion resistance suited for general construction environments, while the patented thread design cuts installation time and reduces the physical effort required to drive anchors into high-strength concrete. Whether you are anchoring structural components or securing fixtures to concrete, this concrete screw anchor provides a confident, removable connection without the complications of traditional expansion anchors.

Key Features

• Patented thread design taps into concrete during installation - delivers keyed engagement that resists pull-out and reduces the risk of anchor slip over time
• Designed for standard ANSI tolerance drill bits - no special or proprietary tooling required, keeping installation straightforward and cost-effective
• Low installation torque in concrete and masonry - reduces installer fatigue on high-volume jobs and speeds up overall productivity
• Universal anchor for normal-weight concrete and grouted or solid masonry - eliminates the need to stock separate anchors for different base materials
• Ratchet teeth on the underside of the hex washer head lock against the fixture - prevents the anchor from backing out under load or vibration
• Reduced edge and spacing distances compared to traditional expansion anchors - allows closer placement to a free edge, giving you more layout flexibility in tight concrete applications
• Fully removable design - anchors can be extracted and reinstalled if fixture adjustments are needed, reducing costly rework
• Bright zinc-plated finish on carbon steel - provides corrosion protection suitable for interior and general construction use

Why This Product

• When layout space is limited, this screw anchor's ability to be installed closer to free edges than traditional expansion anchors means fewer compromises on fixture placement - a practical advantage in constrained concrete work
• The patented thread design cuts into high-strength concrete with low torque, meaning faster installs and less wear on tools and installers during repetitive anchoring tasks
• The fully removable, one-piece design simplifies adjustments and eliminates the waste of destroying an anchor during disassembly - a real benefit on projects where fixture positioning may need to change
• Compatibility with standard ANSI drill bits means no specialty tooling investment - this anchor fits into an existing workflow without adding equipment costs

Frequently Asked Questions

Can this anchor be removed after installation?

Yes. The Screw-Bolt+ is fully removable, which means anchors can be backed out and, if needed, reinstalled to accommodate fixture adjustments or project changes.

What drill bit do I need to install this anchor?

This anchor is designed for use with standard ANSI tolerance drill bits - no proprietary or special-purpose bits are required, so it works with tooling already common on most job sites.

What base materials is this anchor rated for?

According to the product data, approved base materials include normal-weight concrete and grouted or solid masonry. It is not listed for use in lightweight or sand-lightweight concrete based on this product's specifications.

How does the hex washer head design improve holding performance?

The underside of the hex washer head features ratchet teeth that lock against the fixture surface during installation. This mechanical engagement helps prevent the anchor from loosening or backing out under load or vibration.
