The DeWALT Anchors and Fasteners Power-Stud+ SD1 3/4" x 6-1/4" 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 hex nut anchor delivers confident holding power across a wide range of base materials - including normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry. Designed to meet demanding structural and construction fastening needs, the Power-Stud+ SD1 is a go-to wedge anchor for contractors and installers who need dependable expansion anchoring in variable concrete conditions.

Key Features

• Fully threaded, torque-controlled wedge expansion design - ensures a controlled, measurable set in concrete so you can verify proper installation every time
• Consistent performance in high and low strength concrete - reduces the need to assess concrete strength before installing, broadening job site applicability
• Nominal drill bit size matches anchor diameter (3/4") - simplifies tool selection and eliminates guesswork when drilling pilot holes
• Anchor can be installed through standard fixture holes - no oversized clearance holes needed, allowing faster and more accurate positioning of hardware and structural elements
• Length ID code and identifying marking stamped on head of each anchor - makes field verification straightforward and ensures the correct anchor is confirmed after installation
• Anchor design allows for follow-up expansion after setting under tensile loading - the wedge can continue to expand as load is applied, helping maintain holding integrity over time
• Zinc plated carbon steel body and expansion clip - provides a corrosion-resistant silver finish suitable for interior concrete and masonry applications
• Hex nut head style with included nut and washer - ready to install without sourcing additional hardware, saving time on the job

Why This Product

• Engineered for cracked concrete environments - most wedge anchors are rated only for uncracked concrete, but the Power-Stud+ SD1 is specifically designed for consistent performance in cracked concrete, making it appropriate for seismically active regions or aging structures where cracking is likely
• Broad base material compatibility - works in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry, so a single anchor type can serve multiple substrate conditions across a project
• Torque-controlled setting method - provides a verifiable installation process with a defined torque value, supporting quality control requirements on inspected or engineered jobs
• From DeWALT Anchors and Fasteners - a brand with a dedicated line of anchoring and fastening solutions, the Power-Stud+ SD1 is built to consistent manufacturing standards with identifying markings on every anchor head for traceability

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 concrete cracking may be present or expected.

What drill bit size should be used when installing this anchor?

The nominal drill bit size is the same as the anchor diameter. For this 3/4 in. anchor, you would use a 3/4 in. drill bit - eliminating the need to consult a separate sizing chart.

Does this anchor come with a nut and washer?

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

What base materials are compatible with the Power-Stud+ SD1?

Compatible base materials include normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry. This broad compatibility makes it suitable for a wide range of commercial and structural concrete anchoring applications.
