The DeWALT Anchors and Fasteners Power-Stud+ SD1 1/2" x 3-3/4" 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 the structural holding power demanded by contractors and engineers working with concrete and masonry base materials. Whether you are anchoring structural steel, machinery, or other heavy fixtures, this wedge expansion anchor is designed to perform predictably in a wide range of concrete conditions - from normal-weight concrete to sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry.

Key Features

• Fully threaded, torque-controlled wedge expansion design - provides consistent clamping force and reduces the risk of under- or over-setting during installation
• Consistent performance in high and low strength concrete - gives installers confidence across varying job site conditions without needing multiple anchor types
• Nominal drill bit size matches the anchor diameter - simplifies the installation process and reduces the chance of hole-sizing errors
• Anchor can be installed through standard fixture holes - allows through-fixture installation, saving time by setting the anchor after the fixture is positioned
• Length ID code and identifying marking stamped on the head of each anchor - makes on-site verification and inspection straightforward without removing the anchor
• Anchor design allows for follow-up expansion after setting under tensile loading - maintains holding performance even when the anchor experiences load after initial installation
• Zinc plated carbon steel body and expansion clip - provides a durable, corrosion-resistant finish suited to typical interior concrete and masonry applications
• Hex nut head style with included nut and washer - speeds up assembly and ensures a complete, ready-to-install fastener right out of the box

Why This Product

• Rated for both cracked and uncracked concrete - this single anchor handles the structural variability found on real job sites, reducing the need to stock multiple anchor types for different concrete conditions
• Compatible with a broad range of base materials including normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry - making it a versatile choice for commercial and industrial concrete anchoring applications
• The follow-up expansion capability under tensile loading means the anchor actively responds to load conditions after setting, helping maintain holding integrity over time in demanding applications
• Zinc plated carbon steel construction balances durability and value, delivering reliable performance for interior structural anchoring applications where a robust yet cost-effective wedge bolt is required

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 suitable for applications where concrete condition may be uncertain or variable.

What drill bit size is needed to install this anchor?

The nominal drill bit size is the same as the anchor diameter. For this 1/2 in. anchor, you would use a 1/2 in. drill bit, which simplifies layout and reduces preparation errors.

Does this anchor include a nut and washer?

Yes. A nut and washer are included with this wedge expansion anchor, so you have everything needed to complete the installation without sourcing additional hardware separately.

What base materials is this wedge bolt approved for?

Suitable base materials include normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry, covering the most common structural concrete anchoring scenarios.
