The DeWALT ANCHORS & FASTENERS Power-Stud+ SD1 Hex Nut Carbon Steel 1" x 12" Wedge Expansion Anchor is a fully threaded, torque-controlled wedge anchor engineered for consistent, reliable performance in both cracked and uncracked concrete. Designed for demanding structural fastening applications, this heavy-duty wedge bolt features a zinc plated carbon steel body and expansion clip that deliver premium load-bearing capability in a variety of concrete base materials. Whether you are anchoring structural steel, equipment bases, or framing to concrete slabs, this 1"-diameter anchor offers a dependable connection in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry. A nut and washer are included with each anchor, making it ready to install right out of the box.

Key Features

• Fully threaded, torque-controlled wedge expansion design - provides consistent clamping force and reliable load performance in both cracked and uncracked concrete without guesswork during installation
• Consistent performance in high and low strength concrete - allows contractors to use the same anchor specification across varying concrete strengths on the same job site
• Nominal drill bit size matches anchor diameter - simplifies tool selection and reduces the chance of mis-drilled holes, speeding up installation
• Anchor can be installed through standard fixture holes - eliminates the need to remove the fixture before setting the anchor, saving significant labor time on large installations
• Length ID code and identifying marking stamped on the head of each anchor - enables quick field verification of the correct anchor without referencing packaging, reducing installation errors
• Anchor design allows for follow-up expansion after setting under tensile loading - maintains holding strength as loads are applied, adding a built-in safety margin in structural applications
• Zinc plated carbon steel body and expansion clip - protects against corrosion in standard interior concrete environments while delivering a durable, long-lasting connection
• Hex nut head style with included nut and washer - provides a complete, ready-to-install fastening assembly with no additional hardware required for a standard installation

Why This Product

• Engineered for cracked and uncracked concrete - this anchor is specifically rated for use in cracked concrete, giving structural specifiers and contractors confidence in applications where concrete cracking is a possibility over the life of the structure
• Broad base material compatibility - suitable for normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry, making it a versatile single-anchor solution across multiple construction substrate types
• Through-fixture installation capability - the ability to install through standard fixture holes means structural elements can be held in position during anchor setting, reducing the need for temporary supports and streamlining the fastening process
• Follow-up expansion under tensile loading - unlike some fixed-expansion designs, this anchor continues to expand as tensile forces are applied, helping maintain holding strength and connection integrity over time

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 concrete cracking may occur over time.

Does the drill bit size need to match the anchor diameter?

Yes. The nominal drill bit size is the same as the anchor diameter - in this case, 1 inch. This simplifies the drilling process and ensures proper fit without requiring a separate bit size reference chart.

Is any additional hardware required to complete the installation?

No additional hardware is needed for a standard installation. A nut and washer are included with the anchor, providing a complete fastening assembly ready for use.

What is the advantage of the follow-up expansion feature?

The anchor design allows for follow-up expansion after setting under tensile loading. This means the anchor continues to expand as tensile forces are applied during and after installation, helping the fastener maintain its holding strength and connection integrity over the life of the application.
