DeWALT Ultracon+ 1/4 in. x 1-3/4 in. Star Flat Head Screw Anchor is a high-performance concrete screw anchor engineered for light to medium duty fastening in concrete, masonry block, brick, and wood base materials. Featuring a gimlet point for self-drilling into wood without pre-drilling, and a distinctive blue Stalgard coating for corrosion protection, this carbon steel anchor delivers a clean, finished appearance alongside reliable holding strength. The high-low thread design provides greater stability and grip, making this screw anchor a dependable choice for window and door frames, lighting fixtures, thresholds, and screened enclosures.

Key Features

• High-low thread design for greater stability and grip - engages more material per revolution, delivering stronger holding power in concrete and masonry applications
• Gimlet point for self-drilling into wood base materials - eliminates the need for pre-drilling in wood, saving installation time and reducing required tools
• Blue Stalgard coating - provides good corrosion protection, extending service life in typical indoor and outdoor environments
• Removable and reusable in wood - allows adjustments or repositioning without sacrificing the fastener, reducing material waste
• Does not exert expansion forces - protects base material integrity near edges and in thinner sections where expansion stress could cause cracking
• No hole spotting required - speeds up installation and simplifies layout for both experienced contractors and DIY users
• Available in several head styles - allows selection of the right profile for flush, countersunk, or finished-surface applications
• Several colors and finishes to match application - supports aesthetically sensitive installations where anchor visibility matters

Why This Product

• The gimlet point enables direct driving into wood base materials without a pilot hole, cutting setup steps and keeping the job moving on mixed-substrate installations
• The high-low thread design provides greater stability and grip in concrete and masonry compared to single-thread profiles, reducing the risk of anchor loosening under load
• The removable design makes this screw anchor reusable in wood substrates, offering practical value on projects where adjustments are likely during installation
• The blue Stalgard coating delivers good corrosion protection, making this anchor suitable for applications such as screened enclosures, thresholds, and exterior lighting fixtures where moisture exposure is possible

Frequently Asked Questions

Do I need to pre-drill a pilot hole when installing this anchor into wood?

No. The gimlet point on the Ultracon+ anchor is designed for self-drilling into wood base materials, so no pre-drilling is required when fastening into wood substrates. For concrete and masonry applications, standard installation procedures apply.

Can this anchor be removed and reused?

Yes. The Ultracon+ screw anchor is removable and reusable in wood base materials. This makes it a practical option for installations where adjustments or repositioning may be needed during or after the job.

Will this anchor damage or crack the surrounding base material during installation?

No. The Ultracon+ anchor does not exert expansion forces on the base material. This is an important advantage in concrete, masonry block, or brick applications where expansion stress from other anchor types could cause cracking, particularly near edges or in thinner sections.

What drive type does this anchor require?

This anchor uses a Phillips drive. For the star flat head version, a compatible Phillips driver bit is needed. Always refer to the DeWALT spec sheet for the recommended drill bit size - a 3/16 in. Ultracon+ bit is referenced for standard installation.
