DeWALT Anchors and Fasteners UltraCon SS4 Hex Washer Head Gimlet Point 1/4" X 2-1/4" is a 410 stainless steel screw anchor engineered for light to medium duty fastening in concrete and masonry block base materials. Functioning similarly to what is commonly known as a Tapcon screw, this anchor installs quickly without the need for inserts or adhesives, making it a practical choice for a wide range of concrete fastening tasks. The gimlet point design and hex washer head deliver a clean, finished appearance on screen enclosures, storm shutters, light duty fixtures, and light duty industrial mounts. With a Stalgard coating applied over heat-treated 410 stainless steel, this anchor provides far superior corrosion resistance compared to standard carbon steel fasteners, making it well suited for coastal environments, wet exposure, and other demanding conditions.

Key Features

• 410 stainless steel construction - provides a durable base material with inherent corrosion resistance for long-term performance in concrete and masonry applications
• Special heat treatment - protects the inherent corrosion resistance of the 410 stainless steel, preserving the material's integrity even in aggressive environments
• Stalgard coating provides 1000 hours of salt spray protection when tested in accordance with ASTM B117 - delivers enhanced protection against rust and corrosion well beyond what uncoated carbon steel fasteners can offer
• Hex washer head with gimlet point - allows fast, straightforward installation while leaving a neat, finished appearance at the fastened surface
• Designed for concrete and masonry block - works directly in base material without requiring inserts, reducing installation steps and time on the job
• Serves the same purpose as Tapcon screws - a familiar, proven anchoring concept now elevated with stainless steel material and protective coating for greater durability
• Tested in accordance with ASTM E488 - provides verified performance data for professional and code-sensitive applications
• Miami-Dade County Notice of Acceptance (NOA) No. 21-0201.08 and Florida Statewide Product Approval FL29068.1 - meets rigorous regional approval standards, making it acceptable for use in hurricane-zone construction

Why This Product

• The combination of 410 stainless steel and Stalgard coating gives this anchor significantly better corrosion resistance than standard carbon steel screw anchors - a meaningful advantage for installations exposed to moisture, salt air, or outdoor conditions.
• Miami-Dade County Notice of Acceptance and Florida Statewide Product Approval mean this anchor is accepted for use in some of the most code-demanding construction environments in the country, giving contractors confidence on regulated projects.

Frequently Asked Questions

What base materials is the UltraCon SS4 anchor designed for?

This screw anchor is designed for use in concrete and masonry block base materials, covering a broad range of light to medium duty fastening tasks in both residential and commercial construction.

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, offering significantly enhanced corrosion resistance compared to standard carbon steel fasteners. This makes the anchor a strong choice for coastal, outdoor, or moisture-exposed installations.

Does this anchor have any regional building code approvals?

Yes. This anchor holds Miami-Dade County Notice of Acceptance (NOA) No. 21-0201.08 and Florida Statewide Product Approval FL29068.1, and it has been tested in accordance with ASTM E488. These approvals make it suitable for use in hurricane-zone and other code-regulated construction environments.

How does the UltraCon SS4 compare to a typical Tapcon screw?

The UltraCon SS4 serves the same general purpose as what is commonly known as a Tapcon screw - threading directly into concrete or masonry without inserts. The key difference is that this anchor is made from heat-treated 410 stainless steel with a Stalgard coating, providing substantially better corrosion resistance than standard carbon steel versions.
