DeWALT Anchors and Fasteners Screw-Bolt+ Hex Washer Head 1/4" x 1-1/4" is a one-piece, heavy duty carbon steel screw anchor built for reliable fastening into normal-weight concrete and grouted or solid masonry. With a bright zinc-plated finish for corrosion resistance and a patented thread design that works with standard ANSI drill bits, this concrete screw anchor is engineered to reduce installation torque and improve jobsite productivity. The fully removable design makes it easy to adjust or reposition fixtures - a practical advantage over many traditional expansion anchors.

Key Features

• Designed for standard ANSI tolerance drill bits - no special tooling required, so installers can use existing drill bits already on hand
• Patented thread design offers toughened threads for tapping high strength concrete - threads engage the base material directly for a strong, reliable mechanical connection
• Low installation torque in concrete and masonry - reduces installer fatigue and speeds up repetitive anchoring tasks
• Universal product for concrete and grouted/solid masonry - one anchor type handles multiple base materials, simplifying procurement and inventory
• Ratchet teeth on underside of hex washer head lock against the fixture - prevents loosening under load and vibration for a more secure fastened joint
• Can be installed closer to a free edge than traditional expansion anchors - allows more flexible layout options and tighter spacing on concrete slabs or walls
• Fully removable after installation - anchors can be backed out and reused or positions adjusted without damaging the base material
• Zinc-plated carbon steel construction - provides a corrosion-resistant finish suitable for interior and protected concrete anchoring applications

Why This Product

• The patented thread design taps directly into high strength concrete, delivering strong keyed engagement without the complexity or bulk of traditional sleeve-style expansion anchors - making it a streamlined solution for concrete fastening.
• Its compatibility with standard ANSI drill bits means no specialty tooling is needed, reducing setup time and keeping installation straightforward on any concrete or masonry jobsite.
• Reduced edge and spacing distances compared to traditional expansion anchors give contractors more layout flexibility, especially near slab edges, openings, or tight structural zones.
• The fully removable design is a practical advantage when installations need to be adjusted or inspected - the anchor backs out cleanly, preserving the base material for reuse.

Frequently Asked Questions

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

This screw anchor is suitable for use in normal-weight concrete as well as grouted and solid masonry. It is a universal product designed to handle both concrete and masonry base materials with a single anchor type.

Does this anchor require specialty drill bits for installation?

No. The Screw-Bolt+ is specifically designed for use with standard ANSI tolerance drill bits, so no specialty or proprietary drill bits are needed. This helps simplify installation and keeps tooling requirements to a minimum.

Can the Screw-Bolt+ be removed after installation?

Yes. The Screw-Bolt+ is fully removable. The anchor can be backed out of the base material after installation, which is a key advantage for applications where fixtures may need to be repositioned or adjusted.

How does the hex washer head design help secure the fixture?

The underside of the hex washer head features ratchet teeth that lock against the fixture surface during installation. This prevents the anchor from loosening under load or vibration, providing a more secure and stable fastened connection.
