Featuring a hex drive and silicon bronze construction, these lag screws deliver reliable long-term strength in decks, fences, marine applications, and other exterior joinery.

Key Features

• Diameter: 3/8 inch; Length: 3-1/2 inches
• Hex head drive for easy fastening with standard wrenches or drivers
• Silicon bronze construction for superior corrosion resistance in outdoor and marine environments
• Ideal for deck boards, fencing, docks, boat houses, and exterior wood joinery

For best results, pre-drill pilot holes slightly smaller than the screw diameter and drive with steady, even pressure.
