Product Details
✓Self-Locking Square Neck: Engineered with a precision-forged square neck beneath the head that bites into wood or locks into square metal holes, preventing the bolt from spinning while the nut is tightened for a secure, one-sided install.
✓Full Thread Maximum Grip: The fully threaded shank provides maximum grip and enhanced fastening power along the entire 3.5-inch length, making it ideal for deep timber connections and heavy-duty structural DIY projects.
✓304 Marine Grade Stainless: Forged from premium 18-8 (304) Stainless Steel for superior corrosion defense. Essential for outdoor structures, coastal decks, docks, and ACQ pressure-treated lumber applications.
✓Extended Structural Strength: The 3/8 diameter delivers professional-grade shear resistance. At 3.5 long, these bolts are Well-suited for through-bolting thick posts, beams, and heavy structural timber framing.
✓Snag-Free Aesthetic Finish: The smooth, domed round head provides a professional, low-profile finish without sharp edges, ensuring safety and aesthetics for fencing, outdoor furniture, and playground equipment.
