The DeWALT ANCHORS & FASTENERS Power-Stud+ SD1 Hex Nut Carbon Steel Wedge Expansion Anchor (5/8" x 7") is a fully threaded, torque-controlled wedge bolt engineered for consistent, reliable performance in both cracked and uncracked concrete. Designed with a zinc plated carbon steel body and expansion clip, this heavy-duty wedge anchor delivers dependable holding strength across a range of concrete base materials - making it a go-to choice for structural attachment, equipment mounting, and concrete fastening applications where performance cannot be compromised. A nut and washer are included with each anchor.

Key Features

• Fully threaded, torque-controlled wedge expansion design - ensures consistent clamping force and secure anchoring in both high and low strength concrete without guesswork during installation
• Zinc plated carbon steel body and expansion clip - provides a durable silver finish that resists corrosion during typical interior and sheltered construction applications
• Nominal drill bit size matches the anchor diameter (5/8") - simplifies hole preparation by eliminating the need for a separate, oversized bit and reducing the chance of installation error
• Installs through standard fixture holes - no need to remove the fixture during installation, saving time and effort on the job site
• Length ID code and identifying marking stamped on the head of each anchor - allows quick visual verification that the correct anchor is installed, supporting quality control and inspection
• Follow-up expansion after setting under tensile loading - the anchor self-adjusts to maintain holding strength even under real-world load conditions, improving long-term performance
• Suitable for normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry - broad base material compatibility means one anchor solution works across a variety of job conditions
• Hex nut head style - compatible with standard wrenches and power tools for fast, straightforward installation

Why This Product

• Engineered for performance in cracked concrete - unlike standard wedge anchors that are only rated for uncracked applications, the Power-Stud+ SD1 is specifically designed to maintain holding strength in cracked concrete, addressing one of the most demanding conditions in structural fastening
• Single drill bit simplicity - because the nominal drill bit size is the same as the 5/8" anchor diameter, installers need only one bit size to prep and set, reducing setup time and the risk of mismatched tooling
• Through-fixture installation capability - the anchor can be installed through standard fixture holes, which means fixtures do not have to be removed and re-positioned, streamlining the overall installation process on busy job sites
• Broad base material compatibility - rated for normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry, this carbon steel wedge bolt adapts to a wide range of structural and commercial construction scenarios without requiring a different anchor for each substrate

Frequently Asked Questions

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 appropriate for structural applications where cracking in the base material is possible or expected.

What drill bit size do I need to install this anchor?

The nominal drill bit size is the same as the anchor diameter, which is 5/8 in. This means no oversized or specialty bit is required - a standard 5/8 in. drill bit is all that is needed for proper hole preparation.

Does the anchor need to be set before the fixture is placed?

No. This anchor can be installed through standard fixture holes, so you do not need to remove the fixture during installation. The bolt passes through the fixture hole and into the pre-drilled concrete hole in a single step.

What is the body material and plating on this anchor?

The anchor is manufactured with a carbon steel body and expansion clip, finished with zinc plating for a silver appearance. A nut and washer are included with each anchor.
