Product Details
✓PREMIUM 304 STAINLESS STEEL Crafted from high-quality 18-8 (304) stainless steel, these carriage bolts offer superior rust and corrosion resistance. Ideal for outdoor structures, garden projects, and coastal environments.
✓EXTRA LONG FULL THREAD DESIGN The 4-inch length combined with a full thread design offers maximum versatility. It ensures a secure, tight fit even when joining varying material thicknesses, without the limit of a smooth shank.
✓SELF-LOCKING SQUARE NECK Features a precision-engineered square neck that bites into wood to prevent spinning. This allows for easy one-sided tightening during installation, making it ideal for deep-hole fastening.
✓SMOOTH SAFETY FINISH The domed round mushroom head provides a professional, low-profile appearance without sharp edges. Ideal for garden trellises, fences, and outdoor structures where safety is a priority.
✓SPECIFICATIONS & NOTE Package includes 20 pieces of 1/4-20 x 4 carriage bolts only. Nuts and washers are NOT included. We recommend pre-drilling a 1/4 hole for a professional, precise fit.
