DeWALT Anchors and Fasteners Screw-Bolt+ Hex Washer Head 5/8 in. x 4 in. is a heavy duty, one-piece carbon steel screw anchor designed for secure fastening into normal-weight concrete and grouted or solid masonry. With a bright zinc-plated finish that resists corrosion and a patented thread design engineered for use with standard ANSI tolerance drill bits, this anchor delivers reliable holding strength while significantly reducing installation torque - making it a practical choice for contractors, construction crews, and maintenance professionals working with concrete anchoring applications. The ratchet teeth on the underside of the hex washer head lock against the fixture for a stable, confident connection, and the anchor remains fully removable when adjustments or repairs are needed.

Key Features

• Designed for standard ANSI tolerance drill bits - works with common drill bit sizes already on the job site, eliminating the need for specialty tooling and saving time during setup
• Patented thread design offers toughened threads for tapping high strength concrete - threads cut directly into the base material for a keyed mechanical engagement that provides dependable load transfer
• Low installation torque in concrete and masonry - reduces operator fatigue and speeds up installations, especially on high-volume fastening tasks
• Universal product for concrete and grouted/solid masonry - one anchor type covers multiple base materials, simplifying job site inventory
• Ratchet teeth on the underside of the hex washer head lock against the fixture - prevents the head from backing out and maintains consistent clamping force against the attached material
• Can be installed closer to a free edge than traditional expansion anchors - allows greater flexibility in anchor placement and helps avoid costly layout restrictions near slab edges or openings
• Zinc-plated carbon steel construction - provides a corrosion-resistant surface appropriate for interior and protected concrete fastening environments
• Fully removable design - anchors can be extracted and reinstalled without damaging the base material, supporting adjustable or temporary connections

Why This Product

• If your project involves fastening near slab edges or tight spacing constraints, the Screw-Bolt+ allows reduced edge and spacing distances compared to traditional expansion anchors - giving you more placement options without compromising the connection
• The patented thread design taps directly into the hole during installation, creating a keyed engagement with the base material - no setting tool, no expansion clip, and no multi-component assembly required, streamlining the workflow on any concrete fastening job
• The hex washer head with integrated ratchet teeth locks against the fixture surface, providing a secure and stable connection that resists rotation and backing out over time
• With a one-piece design and full removability, this anchor suits applications where future access, adjustment, or disassembly may be needed - a practical advantage over permanent or non-removable anchor types

Frequently Asked Questions

What base materials is the Screw-Bolt+ 5/8 in. x 4 in. approved for?

This anchor is suitable for use in normal-weight concrete and grouted or solid masonry. It functions as a universal anchor across these base material types, making it a versatile choice for general concrete and masonry fastening work.

Do I need a special drill bit to install this anchor?

No specialty drill bits are required. The Screw-Bolt+ is specifically designed for use with standard ANSI tolerance drill bits, so it works with the same drill bits commonly found on most job sites.

Can this anchor be removed after installation?

Yes. The Screw-Bolt+ features a fully removable design. The anchor can be extracted from the base material without damaging the hole, which is beneficial for temporary connections or applications where future adjustment or disassembly may be needed.

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 surface of the fixture being fastened. This locking action helps prevent the head from rotating or backing out during and after installation, maintaining consistent clamping pressure on the connected material.
