DeWALT UltraCon SS4 Hex Washer Head Gimlet Point 1/4" x 3-1/4" Screw Anchor by DeWALT ANCHORS & FASTENERS is a 410 stainless steel concrete screw anchor engineered for light to medium duty fastening in concrete and masonry block base materials. Functionally equivalent to what is commonly known as Tapcon screws, the UltraCon SS4 delivers fast, clean installation with a finished appearance that suits both structural and aesthetic applications. The combination of 410 stainless steel construction and a proprietary Stalgard coating makes this anchor a reliable choice for environments where standard carbon steel fasteners would fall short due to corrosion exposure.

Key Features

• 410 stainless steel construction - provides inherent corrosion resistance, making this anchor a suitable upgrade over carbon steel fasteners in damp or corrosive environments
• Special heat treatment process - preserves and protects the natural corrosion resistance of the 410 stainless steel material, ensuring long-term performance integrity
• Stalgard coating rated for 1,000 hours of salt spray protection tested per ASTM B117 - delivers enhanced durability in coastal, industrial, or high-humidity applications where corrosion is a concern
• Hex washer head with gimlet point design - provides a neat, finished appearance after installation and allows for easy thread-starting without requiring pre-drilling of the anchor itself
• Designed for concrete and masonry block - gives installers a fast and reliable anchoring solution for light to medium duty fixtures, mounts, and enclosures
• Serves the same function as Tapcon screws - familiar installation method means no learning curve for crews already experienced with concrete screw anchors

Why This Product

• The Stalgard coating paired with 410 stainless steel construction delivers 1,000 hours of salt spray resistance per ASTM B117 - making this anchor the right choice when standard carbon steel fasteners would corrode prematurely in humid or outdoor environments
• The hex washer head profile leaves a clean, finished look at the fastening point, which matters for visible installations such as screen enclosures, storm shutters, and light duty fixtures
• Miami-Dade County Notice of Acceptance (NOA No. 21-0201.08) and Florida Statewide Product Approval (FL29068.1) mean this anchor meets demanding regional code requirements without additional research or substitution requests
• Tested in accordance with ASTM E488, this anchor carries independent verification of its load performance in concrete and masonry - giving engineers and inspectors confidence in the fastening system

Frequently Asked Questions

What base materials is the UltraCon SS4 designed to anchor into?

The UltraCon SS4 is designed for use in concrete and masonry block base materials, making it suitable for light to medium duty fastening applications in both poured concrete and CMU block construction.

How does the Stalgard coating improve corrosion resistance compared to uncoated stainless steel?

The Stalgard coating provides 1,000 hours of salt spray protection when tested in accordance with ASTM B117, complementing the inherent corrosion resistance of the 410 stainless steel body. A special heat treatment is also applied to further protect that natural resistance, making the UltraCon SS4 significantly more durable than carbon steel fasteners in harsh or humid environments.

What approvals and listings does the UltraCon SS4 carry?

The UltraCon SS4 has been tested in accordance with ASTM E488, holds Miami-Dade County Notice of Acceptance (NOA) No. 21-0201.08, and carries Florida Statewide Product Approval FL29068.1. It is also specified under CSI Division 03 16.

Is this anchor comparable to a Tapcon screw?

Yes. The UltraCon SS4 serves the same purpose as what is commonly known as a Tapcon screw. It is a concrete screw anchor that installs directly into pre-drilled holes in concrete or masonry block, offering a fast, familiar installation process for experienced crews.
