The DeWALT Power-Stud Hex Nut 304 Stainless Steel 1/2" x 3-3/4" Wedge Expansion Anchor is a fully threaded, torque-controlled wedge expansion anchor engineered for reliable medium duty anchorage in solid concrete and grout-filled concrete masonry. Constructed from Type 304 stainless steel, this wedge bolt resists corrosion in demanding environments - including food processing facilities, water treatment plants, and other wet or chemically aggressive settings - making it a dependable choice wherever carbon steel anchors would be at risk of deterioration. The hex nut head style accepts standard wrenches for straightforward installation, and the fully threaded shank ensures consistent load distribution along the embedment depth. Available in a 50-piece pack for project-ready convenience.

Key Features

• Fully threaded, medium duty all-purpose anchor design - provides consistent holding strength along the entire embedded length, reducing the risk of pull-out in concrete applications
• Length ID stamped on each threaded anchor - eliminates guesswork on the job site so installers can quickly confirm the correct anchor without stopping to measure
• Anchors can be installed through the fixture, hole spotting not required - saves layout time and speeds up installation by allowing the anchor hole to be drilled directly through the mounted fixture
• Chamfered impact section prevents damage to threads - protects thread integrity during driving so the hex nut engages cleanly and torque can be applied accurately
• Clip design prevents spinning during installation - keeps the anchor body stationary while the nut is tightened, making single-person installation practical and efficient
• Nominal drill bit diameter same as anchor diameter - eliminates confusion when selecting the correct drill bit, ensuring a proper fit and optimal expansion in the base material
• Type 304 stainless steel construction - delivers strong corrosion resistance in wet, humid, and chemically active environments such as marine-adjacent sites and food and beverage facilities
• Torque-controlled expansion mechanism - ensures predictable, consistent anchor set with a standard torque wrench, reducing the chance of under-setting or over-driving

Why This Product

• The Type 304 stainless steel material makes this wedge bolt well suited for corrosion-prone environments like water treatment plants, food and beverage processing facilities, and outdoor structural anchorage where moisture exposure is a concern.
• The through-fixture installation capability - combined with the anti-spin clip and chamfered impact section - streamlines the anchor setting process, reducing labor time and minimizing the risk of installation errors on retrofit and new construction projects alike.
• The length ID stamping on every anchor provides a quick visual verification step, giving inspectors and installers confidence that the correct embedment depth is being achieved without additional measurement tools.
• Sold in a 50-piece pack, this anchor is practical for contractors and maintenance teams who need consistent, job-ready quantities for lighting standards, base plates, sills, support ledgers, and machinery anchorage.

Frequently Asked Questions

What base materials is this anchor rated for?

The DeWALT Power-Stud wedge expansion anchor is designed for use in solid concrete and grout-filled concrete masonry only. It is not intended for use in hollow or ungrouted masonry applications.

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

The nominal drill bit diameter is the same as the anchor diameter - for this 1/2 in. anchor, use a 1/2 in. carbide-tipped drill bit. This simplifies bit selection and ensures proper hole sizing for correct wedge expansion.

Can this anchor be installed through an attached fixture?

Yes. The Power-Stud anchor is designed for through-fixture installation, meaning hole spotting is not required. The anchor hole can be drilled directly through the fixture already held in position, saving layout time during installation.

Why is 304 stainless steel specified for this anchor, and when should it be used instead of a plated anchor?

Type 304 stainless steel provides significantly greater corrosion resistance than standard zinc-plated anchors. It is the appropriate choice for applications in wet or chemically active environments such as food and beverage facilities, water treatment plants, and outdoor settings where long-term moisture exposure would degrade a carbon steel fastener.
