42CrMo CAT B Breaker Through Bolt / Side Bolt High Tensile Fastening Spare Parts For Excavator Hammer

CAT B series through bolt and side bolt, also called tie connecting bolts, are vital high-strength fastening fasteners suitable for all CAT B medium hydraulic breakers ranging from B12 to B90. These bolts lock front head, main cylinder and rear accumulator tightly into one integrated assembly, widely applied in municipal demolition, road reconstruction, landscaping excavation and medium quarry secondary rock crushing projects.

Fabricated with premium 42CrMo alloy steel via integral forging and quenching tempering heat treatment. The finished bolts deliver supreme tensile strength and anti-fatigue performance to withstand continuous pulling force and vibration generated by high-frequency striking loads.

Precision thread rolling and surface hardening treatment avoid thread slipping, stretching or breakage under heavy working conditions. Standard OEM dimension allows direct replacement to restore tight assembly clearance, lower abnormal vibration and extend service life of internal wearing spare parts.

Each batch of bolts passes tensile load test, fatigue cycling inspection and thread matching verification to meet original equipment interchange standards. Full model stock supports small retail maintenance orders and large bulk wholesale for construction contractors and machinery rental firms. Custom length, diameter and anti-rust surface treatment can be customized for global machinery maintenance factories and spare parts dealers.
