About this item
Product details
PrimeSource 3.5 in. Hex Lag Screws are engineered for easy installation and reliable performance in demanding wood-to-wood structural applications. These carbon steel exterior screws feature a hex head with an integrated washer, making them ideal for projects that require a strong and secure connection. The hex drive screw design allows for efficient fastening, while patented thread serrations eliminate the need for pre-drilling and help increase installation speed by requiring up to 40% less driving torque. The exterior screw is coated with a high corrosion-resistant finish, providing superior protection when used in treated lumber or outdoor environments. Each screw is stamped with its length on the head for quick identification and easier on-site inspections. Recommended for general use, these lag screws are building code listed and load rated, ensuring dependable performance for construction and outdoor projects. Choose PrimeSource for your next project when you need a long screw with washer for secure, lasting results.
