5/16x3-1/4 Anchor

Star drive style: Also known as Torx, this drive provides 6 contact points, and is designed to reduce slippage and camout when tightening the screw Epoxy coating: 4-layer epoxy coating provide enhanced corrosion resistance, making them ideal for use in pressure-treated wood and outdoor decking, as they prevent staining and ensure long-lasting durability. High Strength: Manufactured from heat-treated carbon steel to increase strength, allowing it to withstand higher loads and stresses, and durability, making it more resistant to wear and abrasion. Superior Strength Design: Wide, serrated threads cut fast, easy, and clean into concrete. The serrations help cut into the concrete more efficiently, reducing installation torque and making it easier to drive into harder materials like concrete.
