DeWALT Screw-Bolt+ Hex Washer Head 3/8" x 1-3/4" Screw Anchor by DeWALT ANCHORS & FASTENERS is a heavy-duty, one-piece carbon steel screw anchor designed 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 engineered for standard ANSI drill bits, this concrete screw anchor delivers low installation torque, fast productivity, and full removability - making it a practical choice for structural and general concrete fastening applications.

Key Features

• Designed for standard ANSI tolerance drill bits - works with the drill bits you already own, no special tooling required, reducing job site preparation time
• Patented thread design offers toughened threads for tapping high-strength concrete - threads tap directly into the base material for a secure, keyed engagement that resists pullout
• Low installation torque in concrete and masonry - reduces installer fatigue and speeds up workflow on large fastening tasks
• Universal product for concrete and grouted or solid masonry - one anchor handles multiple base materials, simplifying procurement and inventory
• Ratchet teeth on the underside of the hex washer head lock against the fixture - prevents loosening under load and vibration for a more dependable connection
• Can be installed closer to a free edge than traditional expansion anchors - allows greater layout flexibility and reduces the risk of cracking near slab or wall edges
• Zinc-plated carbon steel construction - provides a corrosion-resistant surface finish suited for interior concrete and masonry applications
• Fully removable after installation - anchors can be backed out and reused or replaced, which is useful during inspection, repositioning, or phased construction

Why This Product

• The patented screw thread design taps directly into the concrete without the need for an expansion mechanism, giving installers a simpler one-step installation process with less hardware complexity than traditional expansion anchors
• The hex washer head with built-in ratchet teeth locks the anchor against the fixture surface, solving the common problem of anchors backing out under cyclic load or vibration
• Reduced edge and spacing distances compared to traditional expansion anchors give layout designers more flexibility, especially near slab edges, corners, or closely spaced fastening patterns
• Full removability makes this screw anchor well suited for applications where adjustments, inspections, or temporary connections are anticipated - unlike adhesive or expansion anchors that are typically permanent once set

Frequently Asked Questions

What base materials is this screw anchor compatible with?

The DeWALT Screw-Bolt+ is designed for use in normal-weight concrete and grouted or solid masonry. It is a universal anchor suitable for both concrete and masonry base materials in a single product.

What size drill bit do I need to install this anchor?

The Screw-Bolt+ is designed for use with standard ANSI tolerance drill bits. No special or proprietary drill bits are required, allowing you to use drill bits already on hand for a 3/8 in. hole.

Can this anchor be removed after installation?

Yes. The Screw-Bolt+ is fully removable. The screw threads tap into the base material during installation, but the anchor can be backed out when needed for repositioning, adjustment, or replacement.

What makes the hex washer head design advantageous over a standard hex head?

The hex washer head on the Screw-Bolt+ features ratchet teeth on its underside that lock against the fixture surface during installation. This mechanical locking action helps prevent the anchor from backing out under load or vibration, providing a more secure and stable connection.
