DeWALT Anchors and Fasteners Screw-Bolt+ Hex Washer Head 5/8" x 6" is a heavy-duty, one-piece screw anchor engineered for demanding concrete and masonry fastening applications. Built from carbon steel with a bright zinc-plated and mechanically galvanized finish, this anchor delivers reliable holding power in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick. The finished hex washer head and patented thread design make it a preferred choice for contractors and construction professionals who need a fast-installing, fully removable anchor that works with standard ANSI tolerance drill bits.

Key Features

• Designed for standard ANSI tolerance drill bits - eliminates the need for special tooling, simplifying job-site setup and reducing equipment costs.
• Patented thread design offers low installation torque - reduces operator fatigue and speeds up installation across large concrete or masonry projects, enhancing overall productivity.
• Tough threads for tapping high-strength concrete - the steel threads cut into the base material during installation to create a keyed mechanical engagement, providing a secure, dependable hold.
• Ratchet teeth on underside of hex washer head lock against the fixture - prevents loosening under vibration or load, helping maintain a tight, stable connection once installed.
• Fully removable and reinstallable in the same hole - allows adjustments, repositioning, or removal without damaging the base material, adding flexibility to the installation process.
• Bright zinc-plated and mechanically galvanized finish - provides corrosion resistance to extend the service life of the anchor in a variety of installation environments.
• Reduced edge and spacing distances - the keyed thread engagement allows placement closer to edges than traditional expansion anchors, giving installers more layout flexibility in tight spaces.

Why This Product

• One-piece design simplifies installation - there are no separate components to assemble or lose on the job site. The single-body anchor is easy to identify, handle, and drive, making it a practical choice for high-volume concrete fastening work.
• Wide base material compatibility - suitable for normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick, making this anchor a versatile solution across a broad range of structural and non-structural fastening applications.
• Removable and reusable in the same hole - unlike expansion anchors that deform the base material and cannot be reversed, the Screw-Bolt+ can be fully extracted and reinstalled, reducing waste and rework costs when adjustments are needed.
• Low torque installation with standard drill bits - the patented thread geometry reduces the force required to drive the anchor, which means faster installs, less tool wear, and compatibility with standard ANSI drill bits already on the job site.

Frequently Asked Questions

What drill bit size is required to install this anchor?

The DeWALT Screw-Bolt+ is designed for use with standard ANSI tolerance drill bits sized for a 5/8 in. diameter anchor. No special or proprietary bits are required, making it straightforward to use with tooling already on most job sites.

Can the Screw-Bolt+ be removed and reinstalled?

Yes. The Screw-Bolt+ is fully removable and can be reinstalled in the same hole. This sets it apart from traditional expansion anchors that permanently deform the base material during installation, giving it an advantage when adjustments or repositioning are needed.

What base materials is this anchor approved for?

The Screw-Bolt+ Hex Washer Head 5/8" x 6" is suitable for use in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, concrete masonry, and solid clay brick. It is not intended for use in soft or non-structural base materials.

What is the purpose of the ratchet teeth on the underside of the hex washer head?

The ratchet teeth on the underside of the hex washer head are designed to lock against the fixture surface during installation. This locking action helps prevent the anchor from loosening under load or vibration, maintaining a secure and stable connection over time.
