DeWALT Anchors and Fasteners Screw-Bolt+ Hex Washer Head 1/4" x 3" is a one-piece, heavy-duty screw anchor built for reliable fastening in normal-weight concrete and grouted or solid masonry. This zinc-plated screw anchor combines a patented thread design with a ratcheting hex washer head to deliver fast, secure installation with low torque requirements - making it a practical choice for concrete fastening professionals and contractors working in tight conditions near edges and existing structures.

Key Features

• Patented thread design engineered for standard ANSI tolerance drill bits - eliminates the need for special tooling and reduces installation torque, speeding up productivity on the jobsite
• Toughened threads tap directly into high-strength concrete and masonry during installation - creating a keyed mechanical engagement that delivers strong, dependable holding power
• Ratchet teeth on the underside of the hex washer head lock against the fixture - preventing loosening and improving connection integrity once the fastener is set
• Can be installed closer to a free edge than traditional expansion anchors - expands placement flexibility in applications where spacing is limited
• Universal compatibility with both concrete and grouted or solid masonry base materials - one anchor solution works across a broader range of substrates
• Bright zinc-plated finish - provides corrosion resistance suitable for standard indoor and protected concrete fastening applications
• Fully removable one-piece design - allows for disassembly and repositioning when job conditions require adjustments, reducing waste and rework

Why This Product

• The reduced-edge installation capability means you can fasten closer to slab edges, corners, and openings compared to traditional expansion anchors - critical when working in structurally constrained areas of a concrete structure
• The single-piece design with a hex washer head simplifies installation and identification on the jobsite - fewer components, fewer steps, and no separate setting tool required beyond standard drill bits
• Low installation torque in concrete and masonry reduces operator fatigue during repetitive anchoring tasks - especially valuable in high-volume fastening applications
• Fully removable after installation means this anchor is reusable in situations where fixtures need to be removed or relocated - providing long-term value and flexibility on multi-phase projects

Frequently Asked Questions

What drill bit is required to install the Screw-Bolt+ 1/4" x 3" anchor?

The Screw-Bolt+ is designed for use with standard ANSI tolerance drill bits, so no special or proprietary bit is needed. This keeps installation straightforward using commonly available drilling equipment.

Can this screw anchor be removed after installation?

Yes. The Screw-Bolt+ is fully removable after installation. This makes it a practical choice for applications where fixtures may need to be relocated or adjusted at a later stage.

What base materials is the Screw-Bolt+ 1/4" x 3" suitable for?

This anchor is suitable for use in normal-weight concrete as well as grouted and solid masonry base materials, making it a versatile option across a range of common construction substrates.

How does the hex washer head design benefit the installation?

The hex washer head features ratchet teeth on its underside that lock against the fixture during installation. This prevents the anchor from backing out and helps maintain a secure, stable connection once the fastener is fully set.
