DeWALT Anchors and Fasteners UltraCon SS4 Hex Washer Head Gimlet Point 1/4" X 6" is a 410 stainless steel screw anchor engineered for light to medium duty fastening in concrete and masonry block. Featuring a hex washer head and gimlet point design, this screw anchor installs quickly and cleanly, leaving a finished, professional appearance. The Stalgard coating provides an added layer of corrosion defense beyond standard carbon steel fasteners, making this anchor well suited for demanding environments where moisture and salt exposure are a concern. Whether you are securing screen enclosures, storm shutters, light duty fixtures, or light duty industrial mounts, this anchor delivers reliable performance with minimal installation complexity.

Key Features

• 410 stainless steel construction - provides inherent corrosion resistance for use in wet or corrosive environments where carbon steel fasteners would fail prematurely
• Special heat treatment process - preserves and protects the natural corrosion resistance of the 410 stainless steel, ensuring long-term structural integrity in the base material
• Stalgard coating rated for 1000 hours of salt spray protection tested per ASTM B117 - adds a supplemental barrier against salt and moisture, making this anchor a strong choice for coastal or high-humidity applications
• Hex washer head design - delivers a clean, finished appearance once installed and accommodates standard 5/16" hex drive tools for fast, tool-friendly installation
• Gimlet point tip - bites into concrete and masonry cleanly to guide the anchor into the pre-drilled hole, reducing the chance of misalignment during installation
• Compatible with concrete and masonry block base materials - versatile enough for a wide range of structural and architectural fastening applications, from screen enclosures to light duty industrial mounts
• Functions the same as Tapcon-style screw anchors - familiar installation process for contractors and tradespeople already experienced with concrete screw anchors

Why This Product

Frequently Asked Questions

What base materials is this screw anchor designed to fasten into?

The UltraCon SS4 is designed for use in concrete and masonry block base materials, making it appropriate for a wide range of light to medium duty structural and architectural fastening applications.

How does the Stalgard coating improve this anchor's performance over a standard carbon steel fastener?

The Stalgard coating provides 1000 hours of salt spray protection when tested in accordance with ASTM B117. This significantly enhances the anchor's resistance to corrosion compared to uncoated or carbon steel alternatives, which is particularly valuable in coastal, humid, or salt-exposed environments.

What approvals and listings does the UltraCon SS4 carry?

This anchor has been tested in accordance with ASTM E488, received Miami-Dade County Notice of Acceptance (NOA) No. 21-0201.08, and holds Florida Statewide Product Approval FL29068.1 - confirming its suitability for use in hurricane-zone and wind-driven rain construction environments.

What drive type is needed to install this anchor?

The hex washer head design requires a 5/16" hex driver for installation. A 3/16" drill bit is the recommended reference drill bit size for pre-drilling the hole in the concrete or masonry base material before installing this screw anchor.
