8 Sets 5/16 x 5 Stainless Steel Hex Head Lag Screws with Flat Washers & Bit, Heavy Duty Wood Screws, Rust-Proof Exterior Fasteners for Deck, Fence & Construction

Key Features

• 5/16" x 5" All-in-One Kit – 8 Complete Sets: Includes 8 heavy-duty lag screws, 8 matching narrow washers, and 1 matching 1/2" magnetic socket. Everything you need is in one box—no more searching for matching washers or buying extra tools; start your project the moment it arrives
• Premium 304 Stainless Steel – Lifetime Rust Protection: All components (screws and washers) are forged from Grade A2-70 304 (18-8) Stainless Steel. Engineered for ultimate corrosion resistance, this kit is the ideal choice for coastal areas, high-moisture environments, and pressure-treated lumber
• High-Torque Hex Head & Aggressive Grip: The robust hex head allows for maximum torque without stripping—perfectly matched with the included socket. Sharp, deep threads provide immense pull-out resistance and a vibration-proof, permanent hold in wood or wall studs
• Versatile 5/16" Application – Heavy-Duty Choice: A step up in strength, the 5/16" diameter is perfect for stair stringers, outdoor swings, medium timber framing, and bracket mounting. The narrow washers prevent the screw head from sinking into the wood, maintaining structural integrity
• ANSI Standard & Professional Installation: Meets ANSI B18.2.1 standards for precision. To prevent wood splitting and ensure a flush fit with the narrow washer, we recommend pre-drilling a 7/32" pilot hole. (Note: Length is measured from under the head to the tip)
