Heavy Duty Galvanized Carriage Bolts For Wood
✔️ 1/4 x 3 Inch Square Neck Zinc Plated Self Locking Bolt

These zinc coated carriage bolts connect wooden panels to wooden or metal frames without extra washers. The rounded top sits flush while the square shank bites into predrilled holes to stop rotation during tightening. Perfect for fencing, deck repairs, shed framing, and heavy equipment mounts where reliable grip matters.

✅ 1/4 inch diameter threaded shaft for secure thread engagement
✅ Three inch overall length accommodates thick lumber combinations
✅ Square neck design prevents spinning when driving standard tools
✅ Hot dipped zinc plating shields against moisture and surface decay

💡 Why choose a square neck carriage bolt over a standard hex head for timber framing?
Picking dependable fasteners solves alignment headaches and speeds up job site assembly.
1. The squared profile locks into wood fibers to eliminate slippage during installation
2. Zinc layer resists galvanic corrosion when joined to steel mounting plates
3. Semi flush radius reduces snag hazards in active work zones and maintenance routes
