Product Details
✓Extended Reach for Deep Joining: The 3.25-inch length is specifically designed for through-bolting thick timber layers, such as double 2x4 beams, without the bulk of larger diameter bolts.
✓Full Thread Maximum Grip: Featuring a precision-cut 1/4-20 full thread, these bolts provide consistent clamping power across the entire 3-1/4 span, ensuring a stable and gap-free connection.
✓Outdoor-Ready 304 Stainless: Forged from 18-8 (304) stainless steel to endure rain, snow, and humidity. Highly compatible with ACQ pressure-treated lumber used in modern garden projects.
✓Safety-First Aesthetic Finish: The smooth, snag-free domed head eliminates sharp edges, making it the top choice for family projects like playground swings, slides, and garden benches.
✓Self-Locking Square Neck: The precision square shoulder bites firmly into wood fibers, locking the bolt in place so you can easily tighten the nut with one hand from the opposite side.
