  • Worried about weak joints that wobble or fail? Stop risking your projects with ordinary nails or flimsy screws! These Lag Screws (Lag Bolts) are engineered for maximum holding power. Once properly installed, the connection maintains long-term stability and is resistant to loosening under routine use. Selecting the appropriate tools and ensuring correct installation are key to achieving this lasting reliability.
  • Built for Your Heaviest-Duty Projects. Secure decks, treehouses, furniture, and garage storage with confidence. Our Lag Screws come in diameters from 1/4" to 1/2" to furniture assembly (beds, cabinets, chairs), woodworking projects (joining timber, securing worktops, building frames), and structural uses such as deck building, fence posts, play structures, and outdoor installations. You can easily select the size that best fits your project needs.
  • Durable High-Strength Steel with Protective Coating. Crafted from robust steel and finished with a protective black zinc coating, these Hex Head Screws are built to last. They withstand the elements for outdoor use and provide reliable strength for indoor applications, ensuring your construction maintains its integrity over time.
  • Hex Head Design for Easy, High-Torque Installation. The Hex Head allows for secure gripping with a wrench or socket, enabling powerful tightening without stripping. Sharp points and clean threads start easily and bite deep, while the included flat washers add stability and prevent wood damage.
  • Complete Kit with Everything You Need. Your order includes 50 pieces of 5/16" x 3" Hex Head screws and 50 matching flat washers, plus a complimentary hex driver bit. This convenient set is ready for immediate use, making it the perfect furniture screws and woodworking solution, saving you time and extra purchases.
