Product Details
✓Massive Load-Bearing Diameter: The robust 1/2-inch shank provides industry-leading shear strength and structural integrity, specifically designed for heavy-duty timber framing and anchoring.
✓Full 4-Inch Deep Reach: Well-suited for through-bolting standard 4x4 structural posts or joining multiple heavy beam layers, ensuring a safe, rock-solid connection that smaller bolts can't match.
✓Marine-Grade 304 Stainless: Forged from premium 18-8 (304) stainless steel for maximum defense against saltwater air and corrosive ACQ pressure-treated lumber in outdoor foundations.
✓High-Torque Self-Locking Neck: The heavy-duty square shoulder bites deep into the wood, locking the bolt firmly in place to allow for high-tension tightening from the nut side alone.
✓Tamper-Resistant Safety Dome: The smooth round head provides a professional snag-free finish while preventing unauthorized removal—essential for public docks, parks, and large outdoor structures.
