The DeWALT ANCHORS & FASTENERS Power-Stud+ SD1 Hex Nut Carbon Steel 3/4" x 7" Wedge Expansion Anchor is a fully threaded, torque-controlled wedge bolt engineered for consistent, reliable performance in both cracked and uncracked concrete. With a zinc plated carbon steel body and expansion clip, this wedge anchor delivers dependable holding strength across a wide range of structural applications - including normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry. Whether you are anchoring structural steel, equipment bases, or heavy fixtures, this hex nut anchor is designed to perform where it matters most.

Key Features

• Fully threaded, torque-controlled wedge expansion design - provides consistent, verifiable holding performance in both cracked and uncracked concrete, reducing installation uncertainty on structural jobsites
• Zinc plated carbon steel body and expansion clip - the protective zinc plating helps guard against corrosion while the carbon steel construction delivers the tensile strength required for heavy-duty concrete anchoring
• Nominal drill bit size matches the anchor diameter (3/4") - simplifies tool selection and hole preparation, saving time and eliminating sizing guesswork during installation
• Can be installed through standard fixture holes - eliminates the need to remove fixtures before anchoring, speeding up installation workflows
• Length ID code and identifying marking stamped on the head of each anchor - allows for easy field verification and accurate record keeping without needing additional documentation on hand
• Anchor design allows for follow-up expansion after setting under tensile loading - compensates for minor installation variables and helps maintain holding performance over the life of the connection
• Consistent performance in high and low strength concrete - a single anchor solution works across a broader range of base material conditions, reducing the need to stock multiple anchor types
• Suitable for grouted concrete masonry and concrete over steel deck - expands the range of approved base materials, making this anchor versatile across commercial and industrial construction scenarios

Why This Product

• Engineered for cracked and uncracked concrete - this torque-controlled wedge anchor is purpose-built to maintain consistent load performance even in compromised base materials, making it a dependable choice for structural connections where base material conditions may vary
• Broad base material approval including concrete over steel deck and grouted concrete masonry - fewer anchor types to manage on the jobsite means simplified procurement and reduced risk of using the wrong anchor for the application
• Hex nut head style with nut and washer included - the complete assembly is ready to install right out of the box without sourcing additional hardware separately
• Follow-up expansion capability under tensile loading - the anchor continues to tighten and expand as load is applied, which helps compensate for real-world installation conditions and supports long-term connection integrity

Frequently Asked Questions

Is this anchor suitable for use in cracked concrete?

Yes. The Power-Stud+ SD1 is specifically designed for consistent performance in both cracked and uncracked concrete, making it appropriate for structural applications where base material condition cannot always be controlled.

What drill bit size is required for installation?

The nominal drill bit size is the same as the anchor diameter - 3/4" - which simplifies hole preparation and eliminates the need to use an oversized or undersized bit.

Does the anchor include a nut and washer?

Yes. A nut and washer are included with the anchor, so the assembly is complete and ready for installation without sourcing additional hardware.

Can this anchor be installed through a fixture without removing it first?

Yes. The anchor can be installed through standard fixture holes, which allows the fixture to remain in position during anchoring and speeds up the overall installation process.
