Designed with a flat head carriage bolts with Knurled Neck, these zinc plated carriage bolts 1/4" x 3/4" resist rust and corrosion, ensuring longevity in humid or outdoor environments. Its function is similar to square neck carriage bolts bite into materials like steel or wood, locking firmly to prevent rotation during installation. BulletPoint2 : Vibration-Proof Anchoring Power: The knurled neck’s diamond-shaped texture creates unmatched friction inside pre-drilled holes, stopping loosening even under extreme vibration. Whether securing vertical tracks or curved rail systems, these 1/4 x 3/4 coach bolt with ribbed neck stay anchored. When tightened, they sit flush with surfaces, eliminating protrusions that snag rollers – a game-changer for garage doors needing smooth operation. BulletPoint3 : Industrial-Grade Strength: Forged from high-tensile alloy steel, these 1/4 inch flathead plow bolt ribbed shank bolts handle up to 400 MPa tensile strength. Perfect for plow blades, conveyor belts, or heavy-duty tracks, they withstand shear forces and dynamic loads without bending. The 1/4"-20 threads are CNC-machined for precision alignment, reducing wear on nuts and extending hardware lifespan. BulletPoint4 : Designed for Effortless Installation: No specialized tools needed! The ultra-thin flat head slips seamlessly under track edges, while the ribbed shank grips materials during tightening. Each pack includes lock nuts compatible with 7/16" sockets, ensuring quick, wobble-free assembly. Pre-drill a clean 1/4" hole, insert the bolt, and let the square neck auto-align for foolproof security. BulletPoint5 : Why Professionals Choose Us: 1)Anti-Corrosion Shield: Triple-layered zinc plating outperforms standard galvanization, ideal for coastal or high-moisture areas.2)Versatile Fit: Works with steel, wood, and composite tracks – a must-have for DIYers and contractors. 3)25-Pack Efficiency: Tackle multiple projects without mid-job hardware runs.
