The DeWALT ANCHORS & FASTENERS Power-Stud+ SD1 Hex Nut Carbon Steel Wedge Expansion Anchor (3/8" x 2-3/4") is a fully threaded, torque-controlled wedge expansion anchor engineered for consistent, reliable performance in both cracked and uncracked concrete. Designed to serve structural anchoring needs across a wide range of base materials, this zinc plated carbon steel anchor delivers dependable holding strength whether you are working with normal-weight concrete, sand-lightweight concrete, concrete over steel deck, or grouted concrete masonry. The hex nut configuration makes installation straightforward, and the included nut and washer mean you have everything needed to complete the fastening at the anchor point.

Key Features

• Fully threaded, torque-controlled wedge expansion design - ensures consistent clamping force and predictable load performance in both high and low strength concrete
• Nominal drill bit size matches the anchor diameter - eliminates guesswork during hole preparation, saving time and reducing the risk of installation errors
• Anchor can be installed through standard fixture holes - allows direct through-fixture installation without removing the fixture, speeding up the anchoring process
• Length ID code and identifying marking stamped on the head of each anchor - provides easy on-site verification of the correct anchor being used, supporting quality control
• Anchor design allows for follow-up expansion after setting under tensile loading - maintains holding strength even if the anchor experiences minor movement after initial installation
• Zinc plated carbon steel body and expansion clip - provides a protective finish that helps resist surface corrosion during normal indoor anchoring applications
• Hex nut head style - works with standard wrenches and sockets for efficient torque application during setting
• Suitable for cracked and uncracked concrete - broadens the range of job site conditions where this anchor can be confidently deployed

Why This Product

• Engineered for performance in both cracked and uncracked concrete - this wedge anchor handles the real-world variability of job site concrete conditions without requiring a separate anchor specification for each scenario
• Compatible with a broad set of base materials including normal-weight concrete, sand-lightweight concrete, concrete over steel deck, and grouted concrete masonry - reducing the need to stock multiple anchor types for different substrate situations
• Follow-up expansion capability under tensile loading means the anchor self-adjusts to maintain grip if minor settling occurs after installation - adding an extra layer of reliability in demanding applications
• Matching drill bit and anchor diameter simplifies hole preparation and helps ensure proper fit every time - reducing installation mistakes and keeping projects on schedule

Frequently Asked Questions

What drill bit size should I use to install this anchor?

The nominal drill bit size is the same as the anchor diameter, which is 3/8 in. This makes hole preparation simple and ensures a properly sized hole for correct anchor expansion and holding performance.

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 conditions where concrete integrity may vary across a job site.

Does this anchor need to be installed before placing the fixture, or can it go through the fixture hole?

The anchor can be installed through standard fixture holes, so you do not need to remove the fixture during installation. This simplifies the anchoring process and saves time on the job site.

What happens if the anchor shifts slightly after being set?

The anchor design allows for follow-up expansion after setting under tensile loading. This means the anchor can continue to expand and maintain its grip if minor movement occurs after initial installation, helping preserve holding strength over time.
