Lag Screws for Construction Projects


Use lag screws, the construction industry standard, for a stronger bond while fastening pieces of lumber together. Also called lag bolts, lag screws are commonly used in projects involving heavy load-bearing areas like decking, outdoor play equipment or staircases.


Browse a variety of structural screws tailored to your home improvement project. Select screws with superior corrosion and rust protection with an epoxy finish that won't bleed or stain your lumber for exterior building projects like decking. Interior lag screws can be used for fastening wood-to-wood and metal-to-wood. All lag screws come with a hex head so they can be easily driven with simple wrenches.


For your next construction project, heavy-duty wood screws are available in a variety of lengths, widths, and packaging. You can find lag screws that don't require predrilling to save you time. Consider purchasing structural screws in bulk to save you money as well.
