Features
- Extended 4-Inch Reach: Specifically engineered to fully penetrate standard 4x4 posts (3.5 actual thickness) or join thick multi-layer beams with space for washers and nuts.
- Heavy-Duty 5/16 Diameter: The robust 5/16-inch shank offers superior shear resistance and load-bearing capacity compared to 1/4 bolts, essential for structural outdoor joints.
- Premium 304 Stainless Steel: Forged from 18-8 (304) stainless steel for maximum rust protection in coastal air, humid gardens, and corrosive pressure-treated wood (ACQ).
- Safety Round Head Design: The smooth, drive-free domed head eliminates sharp protrusions, providing a snag-free finish that is safe for play sets, benches, and deck railings.
- Anti-Rotation Square Neck: The precision square shoulder locks firmly into wood fibers during installation, allowing for easy, one-sided tightening from the nut side.
