Hexagon Bolts

The hexagonal bolt is an externally threaded fastener with a hexagonal head shape, which cooperates with a nut and is used to fasten and connect two parts with through holes.


High-strength hexagonal bolts have the advantages of high precision, high strength, corrosion resistance, and strong stability.


Hex bolts are widely used in construction engineering, ships, railways, electric power, bridges, wind power, high-voltage and ultra-high-voltage equipment, large-scale mechanical equipment, the automobile industry, and other fields.
