The DeWALT ANCHORS & FASTENERS Power-Stud+ SD1 Hex Nut Carbon Steel 1/2" x 7" Wedge Expansion Anchor is a fully threaded, torque-controlled wedge expansion anchor engineered for consistent, reliable performance in both cracked and uncracked concrete. Its zinc plated carbon steel body and expansion clip deliver durable holding power across a wide range of structural anchoring applications - making it a dependable choice for contractors, builders, and maintenance professionals working with concrete and masonry base materials. The anchor's design allows for follow-up expansion after setting under tensile loading, providing added security in demanding structural connections.

Key Features

• Fully threaded, torque-controlled wedge expansion design - delivers consistent clamping force and reliable performance in both high and low strength concrete, reducing the risk of under- or over-setting
• Zinc plated carbon steel body and expansion clip - provides corrosion resistance and premium mechanical performance in standard concrete and masonry environments
• Nominal drill bit size matches the anchor diameter - simplifies tool selection and speeds up installation by eliminating guesswork on hole size
• Installs through standard fixture holes - allows the anchor to be set after the fixture is in place, saving time and improving alignment accuracy on job sites
• Length ID code and identifying marking stamped on the head of each anchor - makes it easy to verify the correct anchor is installed during inspection and quality control
• Follow-up expansion capability after setting under tensile loading - the anchor self-adjusts under load, helping maintain holding strength as conditions change in the base material
• Hex nut head style with included nut and washer - provides a complete, ready-to-install fastening solution without additional hardware sourcing

Why This Product

• Designed specifically for cracked and uncracked concrete - this wedge bolt is suited for real-world structural conditions where concrete cracking is a possibility, giving you confidence the anchor will perform reliably in service
• Compatible with multiple base materials including normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry - making it a versatile fastener for a broad range of commercial and residential construction applications
• The matching drill bit diameter to anchor diameter simplifies the installation process - no need to size up or down, reducing errors and improving consistency across multiple anchor installations
• Nut and washer are included with each anchor - giving you everything needed to complete the connection right out of the packaging, with no additional trips for hardware

Frequently Asked Questions

What base materials is this wedge expansion anchor approved for?

This anchor is designed for use in normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry. It is engineered for consistent performance in both cracked and uncracked concrete conditions.

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

The nominal drill bit size is the same as the anchor diameter. For this 1/2" anchor, you use a 1/2" diameter drill bit - eliminating any guesswork and simplifying installation.

Is this anchor fully threaded, and what does torque-controlled mean?

Yes, the Power-Stud+ SD1 is a fully threaded wedge expansion anchor. Torque-controlled means the anchor is set by applying a specified installation torque to the nut, which drives the expansion clip and locks the anchor securely in the base material for consistent, verifiable holding performance.

Does this anchor come with a nut and washer?

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