Guard Rail Bolt

Guard Rail Bolts are specialized fasteners designed for securing highway guard rails and crash barriers to posts. They feature a round or mushroom head with a square neck that prevents rotation during tightening. Manufactured to ASTM, DIN, and EN standards, they are produced with corrosion-resistant coatings for outdoor durability. They provide strong, vibration-resistant fastening essential for road safety and infrastructure projects. These bolts are widely used in highways, bridges, parking areas, and roadside protection systems.
