Product Details
✓PREMIUM 304 STAINLESS STEEL Crafted from high-quality 18-8 (304) stainless steel, these carriage bolts provide superior rust and corrosion resistance. Ideal for long-term outdoor use, ensuring structural safety in humid and freshwater environments.
✓ADJUSTABLE FULL THREAD DESIGN The 4.5-inch length features a full thread design, offering maximum flexibility for securing materials of various thicknesses. Well-suited for through-bolting where standard partial threads might bottom out.
✓STRUCTURAL HEAVY DUTY GRADE With a 1/2 inch large diameter and precision square neck, these bolts provide massive shear strength for heavy-duty construction. The square neck seats firmly into wood to prevent spinning during installation.
✓IDEAL FOR PRECISION REPLACEMENT Well-suited for professional contractors and DIYers needing a single, high-quality replacement bolt for gazebos, deck posts, dock railings, and heavy outdoor furniture maintenance.
✓SPECIFICATIONS & NOTE Includes 1 Piece of 1/2-13 x 4-1/2 carriage bolt. Nuts and washers are NOT included. We recommend using matching 1/2 stainless nuts and applying lubricant to prevent thread galling during installation.
