DeWALT Anchors and Fasteners UltraCon SS4 1/4" x 4" Hex Washer Head Gimlet Point Screw Anchor is a 410 stainless steel concrete screw anchor engineered for light to medium duty fastening in concrete and masonry block base materials. Built with a hex washer head and gimlet point design, this stainless steel screw anchor installs quickly and cleanly, delivering a neat, finished appearance on every job. With a Stalgard coating layered over 410 stainless steel, it provides substantially enhanced corrosion resistance compared to standard carbon steel fasteners - making it a smart choice for applications where moisture, salt air, or outdoor exposure are concerns.

Key Features

• 410 stainless steel construction - provides a strong, corrosion-resistant base material suited for concrete and masonry fastening in demanding environments
• Stalgard coating with 1000 hours of salt spray protection (ASTM B117) - delivers proven resistance to corrosion and oxidation, extending the service life of the anchor in exterior and coastal applications
• Special heat treatment process - protects the inherent corrosion resistance of the 410 stainless steel material, preserving performance after installation
• Hex washer head design - allows for secure wrench or socket-driven installation and leaves a clean, professional appearance on the finished surface
• Gimlet point tip - enables fast, self-starting engagement into pre-drilled concrete or masonry, reducing installation time on the job
• Light to medium duty rated - ideal for screen enclosures, storm shutters, light duty fixtures, and light duty industrial mounts where reliable holding strength is needed without over-engineering
• Serves the same purpose as commonly known Tapcon screws - familiar installation method with upgraded corrosion protection, making it a direct upgrade path for stainless steel applications
• Miami-Dade County Notice of Acceptance (NOA) No. 21-0201.08 and Florida Statewide Product Approval FL29068.1 - meets stringent wind-zone approval requirements for use in hurricane-prone regions

Why This Product

• Upgraded corrosion resistance over carbon steel - the combination of 410 stainless steel and Stalgard coating means this anchor holds up in wet, coastal, or salt-spray environments where standard carbon steel fasteners would corrode and fail prematurely
• Approved for use in Florida and Miami-Dade County wind zones - contractors working on storm shutters, screen enclosures, or exterior fixtures in high-wind regions can specify this anchor with confidence, backed by NOA and Florida statewide product approval
• Fast, tool-friendly installation in concrete and masonry - the gimlet point and hex washer head work together to reduce drilling and driving effort, keeping crews productive on light to medium duty anchoring tasks
• Manufactured by DeWALT Anchors and Fasteners - a recognized name in professional fastening systems, offering a product that meets ASTM E488 testing standards for concrete anchor performance

Frequently Asked Questions

What base materials is this screw anchor designed for?

This UltraCon SS4 screw anchor is designed for use in concrete and masonry block base materials, making it suitable for a wide range of light to medium duty fastening applications 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. Combined with the special heat treatment applied to the 410 stainless steel material, this anchor offers substantially enhanced corrosion resistance compared to standard carbon steel fasteners - an important advantage in outdoor, coastal, or high-humidity installations.

Is this anchor approved for use in hurricane or high-wind regions?

Yes. This anchor 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, qualifying it for use in high-wind and hurricane-prone jurisdictions.

How does this compare to a standard Tapcon-style concrete screw?

This UltraCon SS4 anchor serves the same installation purpose as what is commonly known as a Tapcon screw, using a similar pre-drilled concrete screw method. However, it is manufactured from 410 stainless steel with a Stalgard coating, offering significantly greater corrosion resistance than typical carbon steel concrete screws - making it a preferred choice where moisture exposure or corrosive conditions are a factor.
