Heavy Duty JCB Hammermaster Through Bolt / Side Bolt for Secure Hydraulic Breaker Assembly

The Heavy Duty JCB Hammermaster Through Bolt and Side Bolt are critical fastening components that hold the hydraulic breaker body together. These high-strength bolts connect the front head, cylinder, back head, and housing into a complete assembly, ensuring structural integrity and stable operation under continuous high-impact working conditions.

During hydraulic breaker operation, through bolts and side bolts are subjected to repeated impact forces, vibration, and heavy tensile loads. Therefore, bolt quality directly affects the safety, durability, and performance of the entire breaker. Our JCB Hammermaster Through Bolts & Side Bolts are manufactured from premium alloy steel using precision machining, thread rolling, and advanced heat treatment processes to deliver superior tensile strength, fatigue resistance, and long service life.

Designed according to OEM specifications, our bolts provide excellent compatibility with original JCB Hammermaster hydraulic breakers and are ideal for equipment maintenance, rebuilding, and aftermarket replacement.
