DeWALT Anchors and Fasteners Power-Stud+ SD1 3/4" x 5-1/2" carbon steel wedge expansion anchor is a fully threaded, torque-controlled fastening solution engineered for reliable, consistent performance in both cracked and uncracked concrete. The zinc-plated carbon steel body and expansion clip deliver premium strength in demanding structural applications, making this wedge bolt a dependable choice for anchoring into normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry. A nut and washer are included with the anchor, so installation can begin right away without sourcing additional hardware.

Key Features

• Fully threaded, torque-controlled wedge expansion design - delivers consistent, predictable holding strength in both cracked and uncracked concrete so installers can trust every anchor set
• Consistent performance in high and low strength concrete - reduces the need to specify different anchors for varying concrete strengths on the same job site
• Nominal drill bit size matches the anchor diameter - simplifies layout and drilling by eliminating confusion over which bit to use
• Anchor can be installed through standard fixture holes - speeds up installation and eliminates the need to pre-position anchors before setting fixtures
• Length ID code and identifying marking stamped on the head of each anchor - allows fast, accurate identification in the field and supports quality control documentation
• Anchor design allows for follow-up expansion after setting under tensile loading - helps maintain clamping force and long-term holding performance as loads are applied
• Zinc-plated carbon steel body and expansion clip - provides a corrosion-resistant finish suitable for interior structural and industrial environments
• Hex nut head style with nut and washer included - simplifies assembly and ensures proper load distribution right out of the box

Why This Product

• Rated for use in cracked concrete - a critical qualification for seismic and structural applications where concrete is subject to movement or stress, reducing the need for separate anchors in mixed-condition installations
• Broad base material compatibility covering normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry - making it a versatile single-anchor solution across many common construction scenarios
• Follow-up expansion capability under tensile loading means the anchor self-adjusts as structural loads are applied, helping to maintain holding performance over the life of the installation
• Stamped length ID code and head markings support on-site inspection and documentation requirements, which is especially valuable on commercial and code-required projects

Frequently Asked Questions

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 simplifies the installation process and eliminates guesswork when selecting the correct bit.

Can this anchor be used in cracked concrete?

Yes. The Power-Stud+ SD1 is specifically designed for consistent performance in both cracked and uncracked concrete, making it suitable for structural and seismic applications where concrete integrity may be compromised.

Does this anchor include a nut and washer?

Yes. A nut and washer are included with the anchor, allowing installation to proceed without sourcing separate hardware.

What does "follow-up expansion" mean for this anchor?

The anchor design allows for additional expansion after initial setting when tensile loads are applied. This means the anchor continues to tighten against the concrete under load, helping to maintain holding performance over the life of the installation.
