The DeWALT ANCHORS & FASTENERS Power-Stud+ SD1 Hex Nut Carbon Steel 3/4" x 12" Wedge Expansion Anchor is a fully threaded, torque-controlled wedge bolt engineered for consistent, reliable performance in both cracked and uncracked concrete. Zinc plated carbon steel construction provides durability and corrosion resistance in demanding structural applications, making this wedge anchor a go-to solution for contractors and builders who need dependable holding power in a wide range of concrete base materials.

Key Features

• Fully threaded, torque-controlled wedge expansion anchor design - delivers consistent, measurable clamping force so installers can verify proper installation with a torque wrench
• Consistent performance in high and low strength concrete - ensures reliable holding power across varying job site conditions without needing different anchor types
• Nominal drill bit size matches the anchor diameter - simplifies tool selection and reduces the chance of installation errors caused by mismatched bit sizes
• Anchor can be installed through standard fixture holes - allows for quicker, more flexible positioning without requiring oversized clearance holes in the attached fixture
• Length ID code and identifying marking stamped on head of each anchor - enables easy field verification and traceability so installers can confirm the correct anchor is in place
• Anchor design allows for follow-up expansion after setting under tensile loading - provides an added margin of safety as the anchor self-adjusts to maintain grip under load
• Zinc plated carbon steel body and expansion clip - provides a corrosion-resistant finish suited for interior structural concrete applications
• Nut and washer included - ready-to-install right out of the box with no need to source additional hardware separately

Why This Product

• Rated for both cracked and uncracked concrete - this wedge bolt is suitable where seismic or dynamic loading creates micro-cracking in concrete, giving engineers and inspectors confidence in the anchor's long-term performance
• Versatile base material compatibility - works in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry, reducing the need to stock multiple anchor types for different substrates
• Follow-up expansion under tensile load - the anchor continues to tighten as load is applied, which helps maintain holding strength even when vibration or movement is present in the structure
• Zinc plated carbon steel construction with hex nut head style - the familiar hex-drive interface works with standard wrenches and impact tools already on the job site, speeding up installation without specialty equipment

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 applications where seismic activity or structural loading may cause micro-cracking in the base material.

What drill bit size should I use to install this anchor?

The nominal drill bit size is the same as the anchor diameter - in this case, 3/4 in. This one-to-one match simplifies tool selection and helps prevent installation errors.

Does this wedge anchor come with a nut and washer?

Yes. A nut and washer are included with each anchor, so no additional hardware needs to be sourced separately before installation.

What base materials are approved for this anchor?

Approved base materials include normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry. It is not intended for use in base materials outside of these categories.
