The DeWALT ANCHORS & FASTENERS Power-Stud+ SD1 Hex Nut Carbon Steel 5/8" x 5" Wedge Expansion Anchor is a fully threaded, torque-controlled mechanical anchor engineered for consistent, reliable performance in both cracked and uncracked concrete applications. With a zinc-plated carbon steel body and expansion clip, this wedge bolt delivers the clamping strength and dimensional precision that structural, commercial, and industrial installers depend on. The hex nut head style makes it compatible with standard installation tools, and the anchor's design allows for straightforward through-fixture installation - saving time and reducing setup complexity on the job site.

Key Features

• Fully threaded, torque-controlled wedge expansion design - provides consistent clamping force and reliable holding values in both cracked and uncracked concrete, reducing uncertainty during structural fastening
• Consistent performance in high and low strength concrete - gives installers confidence across a wide range of base material conditions without requiring different anchor selections
• Nominal drill bit size matches the anchor diameter (5/8") - simplifies tool selection and eliminates guesswork, speeding up layout and drilling on the job site
• Can be installed through standard fixture holes - eliminates the need for oversized or custom holes in attached materials, streamlining installation workflow
• Length ID code and identifying marking stamped on the head of each anchor - allows for quick field verification of the correct anchor and helps maintain documentation accuracy during inspection
• Anchor design allows for follow-up expansion after setting under tensile loading - helps maintain holding capacity over time, even as the anchor experiences real-world load conditions
• Zinc-plated carbon steel body and expansion clip - provides a protective finish that resists corrosion in standard interior and light-duty construction environments
• Hex nut head style - compatible with standard socket wrenches and torque wrenches for precise, controlled installation

Why This Product

• Engineered specifically for cracked concrete applications - many expansion anchors are rated for uncracked concrete only, but the Power-Stud+ SD1 is designed to perform consistently in both cracked and uncracked base materials, making it suitable for a broader range of structural and seismic applications.
• Suitable for multiple base materials including normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry - reducing the need to stock multiple anchor types for different substrate conditions on a project.
• The follow-up expansion capability under tensile loading means the anchor adapts to load-induced movement rather than simply loosening, supporting long-term connection integrity in demanding structural applications.
• Stamped head markings make field inspection and quality control straightforward - each anchor is individually identified, which is valuable on projects requiring documentation of fastener specifications.

Frequently Asked Questions

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

The nominal drill bit size for this anchor is the same as the anchor diameter - 5/8 in. This is one of the convenient design features of the Power-Stud+ SD1, as it removes the need to consult a separate drill size chart.

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. Suitable base materials include normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry.

How do I confirm I have the correct anchor during installation?

Each anchor has a length ID code and identifying marking stamped directly on the head. This allows for quick visual verification in the field and supports accurate record-keeping for inspection purposes.

What happens to this anchor under tensile loading?

The anchor design allows for follow-up expansion after setting under tensile loading. This means the anchor can continue to expand and maintain holding capacity when subjected to real-world tensile forces, supporting long-term connection performance.
