Our hydraulic breaker through bolts are engineered for extreme durability to withstand continuous high-intensity impact work in quarries, mines and demolition sites.

Crafted from premium alloy steel and processed with integrated quenching and tempering heat treatment, these bolts deliver outstanding tensile strength, powerful shock resistance and superior anti-fatigue performance. Unlike ordinary bolts that easily stretch, crack or loosen under frequent heavy blows, our through bolts maintain stable tightness between the breaker’s front head, cylinder and back head during long-hour operation, effectively avoiding component separation, oil leaks and equipment breakdowns caused by bolt failure.

Every bolt undergoes precision CNC machining to guarantee standard thread size and seamless matching with nuts and gaskets. The outer surface is coated with thick anti-rust and anti-corrosion layers, greatly extending service life amid harsh working environments filled with rock dust, mud, water and sharp gravel.

We offer full OEM & ODM customization of dimensions, thread standards and surface treatments to fit most mainstream hydraulic breaker models. Each batch passes strict hardness, tension and impact testing before shipment to ensure consistent long-lasting quality.
