DeWALT Anchors and Fasteners Power-Stud+ SD1 3/4 in. x 10 in. Carbon Steel Wedge Expansion Anchor is a fully threaded, torque-controlled wedge bolt engineered for consistent, reliable performance in both cracked and uncracked concrete. The zinc-plated carbon steel body and expansion clip provide premium holding strength across a wide range of base materials - including normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry. Designed for structural anchoring applications where dependable expansion and load transfer are critical, this hex nut wedge anchor delivers the consistency professionals expect from a trusted anchoring solution.

Key Features

• Fully threaded, torque-controlled wedge expansion design - ensures consistent installation results and reliable clamping force in both cracked and uncracked concrete
• Zinc-plated carbon steel body and expansion clip - delivers premium corrosion resistance for a durable, long-lasting anchor in demanding environments
• Consistent performance in high and low strength concrete - reduces uncertainty on the job site and works across a broad range of concrete conditions
• Nominal drill bit size matches the anchor diameter - simplifies tool selection and speeds up the installation process with no guesswork
• Anchor can be installed through standard fixture holes - eliminates the need for oversized or special-cut holes, saving time and material
• Length ID code and identifying marking stamped on the head of each anchor - allows for quick, at-a-glance verification during and after installation
• Anchor design allows for follow-up expansion after setting under tensile loading - provides added security as the connection is put under load
• Hex nut head style with nut and washer included - provides a complete, ready-to-install assembly right out of the package

Why This Product

• Engineered for cracked and uncracked concrete - this anchor is suited to real-world structural conditions where concrete integrity cannot always be guaranteed, giving you a reliable fastening solution in both scenarios
• Compatible with multiple base materials - normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry - making it a versatile choice for a wide range of commercial and construction projects
• The torque-controlled wedge expansion mechanism allows follow-up expansion under tensile load, meaning the anchor actively responds to the forces placed on it rather than relying solely on the initial installation torque
• The marking stamped on the head of each anchor makes field verification straightforward, reducing the risk of installation errors and supporting quality control on demanding job sites
