The DeWALT ANCHORS & FASTENERS Power-Stud+ SD1 Hex Nut Carbon Steel 3/8" x 7" Wedge Expansion Anchor is a fully threaded, torque-controlled wedge bolt engineered for consistent, reliable performance in both cracked and uncracked concrete. Constructed with a zinc plated carbon steel body and expansion clip, this anchor delivers premium holding strength in a wide range of base materials - making it a dependable choice for structural concrete and masonry fastening applications where performance consistency matters most.

Key Features

• Fully threaded, torque-controlled wedge expansion design - ensures predictable, repeatable load performance across every installation, reducing guesswork on the jobsite
• Consistent performance in high and low strength concrete - gives installers confidence whether working with standard or variable-strength base materials
• Nominal drill bit size matches the anchor diameter - simplifies hole preparation by eliminating the need for a separate oversized bit, saving time and reducing errors
• Can be installed through standard fixture holes - allows anchoring without removing the fixture, speeding up workflow and reducing installation steps
• Length ID code and identifying marking stamped on the head of each anchor - enables fast, accurate identification in the field without referencing separate documentation
• Anchor design allows for follow-up expansion after setting under tensile loading - maintains holding strength even after initial load is applied, adding a reliable safety margin
• Zinc plated carbon steel body and expansion clip - provides a corrosion-resistant finish suited for interior concrete and masonry fastening environments
• Nut and washer included - provides a complete, ready-to-install assembly right out of the package

Why This Product

• Designed specifically for cracked and uncracked concrete - this wedge anchor meets the demands of structural concrete fastening where base material conditions may vary, reducing the need to stock multiple anchor types for different conditions
• Suitable for normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry - its broad base material compatibility makes it a versatile single solution across common construction scenarios
• Torque-controlled expansion mechanism with follow-up expansion under tensile load - delivers peace of mind that the anchor continues to perform after setting, even when subjected to ongoing load forces
• Zinc plated carbon steel construction at a 3/8" diameter by 7" length - balances strength, weight (0.198 lb per anchor), and corrosion resistance for interior structural applications where a reliable hex nut anchor is required

Frequently Asked Questions

Can this anchor be used in cracked concrete?

Yes. The Power-Stud+ SD1 is specifically engineered for consistent performance in both cracked and uncracked concrete, making it suitable for structural applications where base material integrity may vary.

What drill bit size is required to install this anchor?

The nominal drill bit size is the same as the anchor diameter - in this case, 3/8 in. - which simplifies installation and eliminates the need for a separate oversized bit.

Does this anchor include a nut and washer?

Yes. A nut and washer are included with this anchor, providing a complete ready-to-install assembly.

What does "follow-up expansion" mean for this anchor?

The anchor design allows for follow-up expansion after the anchor has been set and tensile loading is applied. This means the expansion clip continues to engage under load, helping to maintain holding strength after initial installation.
