Structural Lag Screws

Lag Screws for Structural Wood Construction

The NOVA™ and YUKON™ structural lag screws are designed specifically for structural wood-to-wood applications where high load capacity and long-term durability are crucial.

Manufactured by Screw Products Inc., a trusted manufacturer recognized for its quality and innovation, these timber screws are available in either a black exterior coating or a stainless steel finish to meet the demands of any heavy-duty project.

They are engineered to be driven directly into wood without the need for pre-drilling, saving time and effort on the job site.

When working with dimensional lumber, engineered wood, or pressure-treated lumber, you need structural lag screws that can deliver uncompromising strength.

Wood Lag Screws for Structural Applications

Structural wood lag screws are versatile fasteners that are ideal for structural applications in both residential and commercial construction. Available in coin head (star drive) and hex head designs, these lag screws simplify installation while ensuring a strong grip and maximum withdrawal strength. The star drive system reduces cam-out and stripping, offering a more controlled drive. The strong, self-tapping thread cuts effectively through materials such as wood, plastic, and sheet metal.

The TER-approved coated versions are perfect for structural wood-to-wood connections requiring approvals or building inspections. They are a dependable choice for engineers, contractors, and quality-minded builders. You can view the full technical evaluation here.

Whether you’re framing a deck, assembling a pergola, or connecting structural beams, structural lag screws provide a secure and lasting hold.

Lag Screws for Wood

When it comes to lag screws for wood, durability in challenging environments is key. Our coated versions feature a high-performance exterior-grade black finish that’s both corrosion-resistant and visually appealing – ideal for exposed fastener applications where aesthetics matter. This black finish has quickly become a favorite among professionals and homeowners seeking both strong connections and modern style.

The 316 stainless steel lag screws are the perfect choice for the toughest environmental conditions, where maximum corrosion resistance is essential. They are code-compliant for use in marine environments with saltwater splash, airborne salts, and areas with de-icing salts. For high-corrosive environments like outdoor coastal areas, surfaces with salt exposure, ground contact treated lumber, shipyards, or polluted industrial areas, you can trust the resilience and enduring quality of the NOVA™ 316 stainless steel lags to consistently deliver optimal performance.

From residential decks to post-frame buildings, these heavy-duty wood screws deliver the strength and durability you need. With options tailored to outdoor conditions and modern preferences, they’re a smart investment for any structural project. For lighter structural needs, multipurpose structural wood screws provide a strong, cost-effective alternative.
