DeWALT Anchors and Fasteners Power-Stud+ SD1 Hex Nut Wedge Expansion Anchor - 3/4" x 8-1/2" is a fully threaded, torque-controlled wedge expansion anchor engineered for consistent, reliable performance in both cracked and uncracked concrete. Manufactured with a zinc plated carbon steel body and expansion clip, this heavy-duty wedge bolt delivers dependable holding strength across a wide range of concrete base materials - making it a go-to choice for structural fastening, equipment anchoring, and concrete-to-fixture connections where performance cannot be compromised.

Key Features

• Fully threaded, torque-controlled design - ensures consistent, measurable installation and predictable load performance in both cracked and uncracked concrete
• Zinc plated carbon steel body and expansion clip - provides a durable, corrosion-resistant finish suited for interior structural applications and demanding concrete environments
• Nominal drill bit size matches anchor diameter - simplifies hole preparation and eliminates the need for specialized bits, speeding up the installation process
• Installs through standard fixture holes - allows the anchor to be set with the fixture already in place, saving time and reducing steps on the job site
• Length ID code and identifying marking stamped on the head of each anchor - enables quick visual verification of anchor size after installation for quality control and inspection
• Anchor design allows for follow-up expansion after setting under tensile loading - maintains holding strength even as loads are applied, adding a layer of performance reliability
• Hex nut head style with included nut and washer - provides a secure, wrench-ready connection right out of the box
• Suitable for normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry - versatile enough to cover a wide range of structural concrete base materials

Why This Product

• Designed for both cracked and uncracked concrete - this wedge expansion anchor performs reliably in real-world conditions where concrete integrity may vary, reducing the risk of anchor failure in demanding structural applications
• Follow-up expansion capability under tensile loading - unlike standard expansion anchors, the Power-Stud+ SD1 continues to expand as tension is applied, which means the anchor maintains its grip even as structural loads shift or increase
• Compatible with a broad range of concrete base materials including concrete over steel deck and grouted concrete masonry - giving contractors and engineers greater flexibility across different job site conditions without switching anchor types
• Zinc plated carbon steel construction with a 3/4" diameter and 8-1/2" length - delivers substantial embedment depth for high-load anchoring tasks where shorter or lighter anchors would be inadequate

Frequently Asked Questions

What types of concrete is the Power-Stud+ SD1 suitable for?

This wedge expansion anchor is designed for use in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry - covering a broad range of structural base materials commonly encountered in commercial and residential construction.

Does this anchor work in cracked concrete?

Yes. The Power-Stud+ SD1 is specifically engineered for consistent performance in both cracked and uncracked concrete, making it appropriate for applications where the condition of the concrete substrate cannot be guaranteed to be free of cracks.

What drill bit size is needed to install this anchor?

The nominal drill bit size is the same as the anchor diameter, which is 3/4 in. This means no specialized or oversized bit is required - a standard 3/4 in. drill bit is all that is needed for hole preparation.

Are a nut and washer included with this anchor?

Yes. A nut and washer are included with the anchor, so the hex nut connection is ready for immediate installation without the need to source additional hardware separately.
