DeWALT Anchors and Fasteners UltraCon SS4 Hex Washer Head Gimlet Point Screw Anchor, 1/4" x 2-3/4" is a 410 stainless steel concrete screw anchor built for light to medium duty fastening in concrete and masonry block base materials. Engineered for contractors and installers who need reliable, corrosion-resistant performance, this screw anchor installs quickly and cleanly - leaving a neat, finished appearance with every application. The UltraCon SS4 serves the same purpose as what is commonly known as Tapcon screws, making it a familiar and trusted solution for anchoring into concrete and block without the mess or wait time of adhesive systems.

Key Features

• 410 stainless steel construction - provides inherent corrosion resistance suited for demanding environments where carbon steel fasteners would degrade over time
• Stalgard coating with 1000 hours of salt spray protection (ASTM B117) - delivers enhanced corrosion resistance beyond standard carbon steel, making this anchor reliable in coastal, humid, or outdoor exposure conditions
• Special heat treatment applied to the 410 stainless steel material - protects and preserves the inherent corrosion resistance of the base metal so performance is not compromised during installation
• Hex washer head design - provides a clean, finished appearance and allows easy installation with standard hex drive tools
• Gimlet point tip - self-starting point helps guide the anchor into the pre-drilled hole accurately and efficiently
• Fast and easy installation - no adhesive, setting tool, or cure time required, reducing labor time on the job
• Compatible with concrete and masonry block base materials - versatile connection design covers the most common structural base materials in light to medium duty fastening applications
• Tested in accordance with ASTM E488 - independently verified performance data gives engineers and inspectors confidence in the anchor's structural reliability
• Miami-Dade County Notice of Acceptance (NOA) No. 21-0201.08 and Florida Statewide Product Approval FL29068.1 - approved for use in high-velocity hurricane zones and throughout Florida, meeting stringent wind load and impact requirements

Why This Product

• Superior corrosion resistance over carbon steel - the combination of 410 stainless steel, special heat treatment, and Stalgard coating provides 1000 hours of salt spray protection (ASTM B117), making this anchor the right choice where moisture, humidity, or coastal conditions are a concern
• Fast, no-adhesive installation - the screw anchor design means no mixing, no cure time, and no special setting tools - installers simply drill and drive, saving time on every anchor point
• Code-compliant for Florida and high-wind applications - Miami-Dade NOA and Florida Statewide Product Approval make this anchor acceptable for screen enclosures, storm shutters, and other wind-critical applications that require documented code compliance
• A recognized alternative to Tapcon-style concrete screws - contractors familiar with Tapcon-type anchors can transition directly to UltraCon SS4 with the same installation process while gaining the added corrosion protection of stainless steel construction

Frequently Asked Questions

What is the Stalgard coating and why does it matter?

Stalgard is a specialized coating applied to UltraCon SS4 anchors that provides 1000 hours of salt spray protection when tested in accordance with ASTM B117. This means the anchor offers enhanced corrosion resistance beyond what uncoated or standard carbon steel fasteners provide - an important advantage in humid, coastal, or outdoor environments where moisture exposure is ongoing.

What base materials are compatible with this screw anchor?

The UltraCon SS4 is designed for use in concrete and masonry block base materials, covering the most common structural substrates in light to medium duty anchoring applications such as screen enclosures, storm shutters, and light duty industrial mounts.

Is this anchor approved for use in Florida wind-load applications?

Yes. The UltraCon SS4 carries Miami-Dade County Notice of Acceptance (NOA) No. 21-0201.08 and Florida Statewide Product Approval FL29068.1. It has also been tested in accordance with ASTM E488, making it suitable for code-compliant installations in high-velocity hurricane zones and throughout Florida.

How does the UltraCon SS4 compare to standard Tapcon-style concrete screws?

The UltraCon SS4 serves the same purpose as what is commonly known as Tapcon screws and installs using the same general process - drill a pilot hole and drive the screw anchor directly into concrete or masonry. The key distinction is that UltraCon SS4 is manufactured from 410 stainless steel with a Stalgard coating, providing significantly greater corrosion resistance than typical carbon steel concrete screws.
