Product Details
✓PREMIUM 304 STAINLESS STEEL Crafted from high-quality 18-8 (304) stainless steel, these carriage bolts offer superior rust and corrosion protection. Ideal for long-term outdoor, coastal, and marine applications.
✓INCREASED 5/16 LOAD STRENGTH The robust 5/16 inch diameter provides higher shear strength and load-bearing capacity than standard 1/4 bolts. Well-suited for structural projects where stability is key.
✓VERSATILE 1-1/4 FULL THREAD Featuring a full thread design, these 1.25-inch bolts provide maximum flexibility for various material thicknesses. It ensures a secure fit whether joining wood-to-wood or metal-to-wood.
✓SELF-LOCKING SQUARE NECK Features a precision square neck that bites into wood to prevent spinning. This allows for easy one-sided tightening, while the smooth round head ensures a safe, snag-free finish.
✓SPECIFICATIONS & NOTE Package includes 5 pieces of 5/16-18 x 1-1/4 carriage bolts only. Nuts and washers are NOT included. We recommend pre-drilling a 5/16 hole for a professional fit.
