DeWALT Anchors and Fasteners UltraCon SS4 Hex Washer Head Gimlet Point 1/4" x 5" Screw Anchor is a 410 stainless steel concrete screw anchor engineered for light to medium duty fastening in concrete and masonry block base materials. Combining the proven performance of a hex washer head gimlet point design with a protective Stalgard coating, this screw anchor delivers enhanced corrosion resistance over standard carbon steel fasteners - making it a reliable choice for exterior applications, screen enclosures, storm shutter installations, and light duty industrial mounts where moisture and salt exposure are concerns. Fast and easy to install, the UltraCon SS4 serves the same purpose as what is commonly known as Tapcon screws while providing a neat, finished appearance after installation.

Key Features

• 410 stainless steel construction - provides inherent corrosion resistance for use in demanding environments where carbon steel fasteners would be prone to rust
• Special heat treatment process - protects and preserves the inherent corrosion resistance of the 410 stainless steel material, maintaining long-term anchor integrity
• Stalgard coating with 1000 hours of salt spray protection (tested per ASTM B117) - significantly extends service life in coastal, high-humidity, and outdoor environments compared to uncoated carbon steel anchors
• Hex washer head design - allows for quick drive with a 5/16" hex driver, speeds up installation, and delivers a clean, professional finished appearance
• Gimlet point tip - self-starting tip aids in accurate positioning and penetration into concrete or masonry block without the anchor walking off-target
• Light to medium duty concrete and masonry application - suitable for a wide range of fastening tasks in solid concrete and masonry block, giving installers versatile single-product coverage
• Direct replacement for Tapcon-style screws - familiar installation process means no additional training or specialized tools beyond what crews already use
• Manufactured by DeWALT Anchors and Fasteners - backed by a recognized name in professional fastening, supporting confidence in product quality and consistency

Why This Product

• For projects exposed to salt air, rain, or high humidity - such as screen enclosures and storm shutters - the Stalgard coating combined with 410 stainless steel construction delivers 1000 hours of salt spray resistance (per ASTM B117), reducing the risk of corrosion-related fastener failure over the life of the installation.
• The hex washer head gimlet point design makes installation fast and straightforward, eliminating the need for pre-drilling a starter hole and allowing the anchor to seat cleanly and evenly - reducing labor time on repetitive fastening tasks in concrete or masonry.
• Tested in accordance with ASTM E488 and carrying Miami-Dade County Notice of Acceptance (NOA) No. 21-0201.08 and Florida Statewide Product Approval FL29068.1, this anchor meets the rigorous wind-load and structural standards required for high-velocity hurricane zone construction and code-compliant installations.
• As a stainless steel alternative to standard carbon steel concrete screws, the UltraCon SS4 fills the gap between basic Tapcon-style fasteners and full 316 stainless anchors - offering meaningful corrosion protection at a practical specification for light to medium duty concrete and masonry work.

Frequently Asked Questions

What base materials is the UltraCon SS4 screw anchor designed for?

The UltraCon SS4 is designed for light to medium duty fastening applications in concrete and masonry block base materials. It is not intended for use in wood or metal substrates.

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 the special heat treatment applied to the 410 stainless steel material, the coating significantly enhances corrosion resistance over standard carbon steel concrete anchors - making the UltraCon SS4 well-suited for outdoor and coastal installation environments.

Does the UltraCon SS4 work the same way as a Tapcon screw?

Yes. The UltraCon SS4 serves the same purpose as what is commonly known as Tapcon screws. It is a concrete screw anchor that threads directly into a pre-drilled hole in concrete or masonry block. The recommended drill bit reference is a 3/16" UltraCon bit, and the hex washer head is driven with a 5/16" hex driver.

What approvals and listings does the UltraCon SS4 carry?

The UltraCon SS4 has been tested in accordance with ASTM E488. It holds Miami-Dade County Notice of Acceptance (NOA) No. 21-0201.08 and Florida Statewide Product Approval FL29068.1, making it a code-compliant choice for high-velocity hurricane zone and statewide Florida construction projects.
