Features
- Heavy-Duty 3 Reach: Precision-engineered to penetrate thick timber, such as standard 4x4 posts (3.5 actual) when countersunk, or joining two 2x4 boards with thick metal brackets.
- Reinforced 5/16 Diameter: The robust 5/16-inch shank provides a 50% increase in cross-sectional strength over 1/4 bolts, ensuring superior shear resistance for load-bearing joints.
- Marine-Grade 304 Stainless: Crafted from premium 18-8 (304) stainless steel for maximum rust prevention. Highly recommended for ACQ pressure-treated lumber and humid environments.
- Safety-First Aesthetic Finish: The smooth, drive-free domed head eliminates sharp edges and snagging, making it the premier choice for playground swings, slides, and garden benches.
- Anti-Spin Square Neck: The precision square shoulder locks firmly into wood fibers, allowing for easy, one-handed tightening of the nut from the opposite side.
