DeWALT Anchors and Fasteners UltraCon SS4 Hex Washer Head Gimlet Point Screw Anchor (1/4" x 1-1/4") is a 410 stainless steel concrete screw anchor engineered for light to medium duty fastening in concrete and masonry block base materials. Designed as a direct alternative to what is commonly known as Tapcon screws, this hex head anchor delivers a clean, finished appearance and installs quickly without the need for setting tools. The Stalgard coating combined with special heat treatment gives this masonry screw anchor enhanced corrosion resistance, making it a reliable choice for demanding environments where standard carbon steel fasteners fall short.

Key Features

• 410 stainless steel construction with special heat treatment - preserves and enhances the inherent corrosion resistance of the stainless steel material, extending service life in corrosive or moisture-exposed conditions
• Stalgard coating provides 1000 hours of salt spray protection tested per ASTM B117 - delivers verified corrosion resistance well beyond uncoated carbon steel fasteners, suitable for coastal, humid, or chemically exposed environments
• Hex washer head design - provides a neat, finished appearance after installation and allows for consistent torque application with a standard 5/16" hex driver
• Gimlet point tip - starts cleanly into pre-drilled masonry without walking or skipping, helping maintain hole alignment during installation
• Fast, easy installation into concrete and masonry block - no setting tool required, reducing labor time and complexity on the job site
• Functionally equivalent to Tapcon-style screw anchors - provides a familiar installation process for contractors already experienced with concrete screw anchors
• Silver finish, 0.25 in. diameter, 1.25 in. fastener length - a compact size well suited for light to medium duty fixture and hardware attachment in masonry substrates

Why This Product

Frequently Asked Questions

What type of base material is this anchor designed for?

The UltraCon SS4 screw anchor is designed for use in concrete and masonry block base materials, making it well suited for light to medium duty fastening applications such as screen enclosures, storm shutters, light duty fixtures, and light duty industrial mounts.

How does the Stalgard coating improve corrosion resistance?

The Stalgard coating provides 1000 hours of salt spray protection when tested in accordance with ASTM B117. Combined with special heat treatment that preserves the inherent corrosion resistance of the 410 stainless steel material, this anchor offers significantly enhanced protection over standard carbon steel fasteners in humid, coastal, or chemically exposed environments.

What approvals and listings does this anchor carry?

The UltraCon SS4 has been tested in accordance with ASTM E488 and carries Miami-Dade County Notice of Acceptance (NOA) No. 21-0201.08 as well as Florida Statewide Product Approval FL29068.1, supporting its use in code-compliant applications in high-wind regions.

Is this anchor compatible with standard Tapcon-style installation methods?

Yes. The UltraCon SS4 serves the same purpose as what is commonly known as Tapcon screws, so contractors familiar with concrete screw anchor installation will find the process consistent. The hex washer head accepts a standard 5/16" hex driver, and the gimlet point starts cleanly into a pre-drilled pilot hole using a 3/16" UltraCon bit.
