42CrMo CAT H Series Through / Side Bolt High Tensile Tie Fastener Lock Front Head And Cylinder As One Unit
CAT H series through bolt and side bolt, also known as integral tie fasteners, are high-load connecting hardware matching small, medium and heavy CAT H hydraulic breakers covering H160 to H410. These bolts lock front head, main cylinder and rear accumulator tightly as a unified assembly structure, suitable for mini-excavator landscaping, municipal road reconstruction and large quarry hard rock crushing projects.
Manufactured from premium 42CrMo alloy steel with forging and quenching tempering heat treatment process. The finished bolts feature outstanding tensile strength and anti-fatigue performance to resist persistent pulling force and whole-machine vibration generated by long-time high-frequency striking.
Precision thread rolling and surface hardening prevent thread slipping, stretching or fracture under harsh working conditions. Standard OEM dimensions support direct on-site replacement to restore tight assembly clearance, reduce abnormal vibration and extend service life of internal bushings, piston and seal kits.
Every batch of connecting bolts undergoes tensile load detection, fatigue cycle inspection and thread matching calibration to reach original equipment interchange standards. Full specifications stock supports single-piece maintenance orders and large bulk wholesale for construction contractors and machinery rental yards. Custom bolt length, diameter and anti-corrosion surface coating customization can be provided for global machinery maintenance factories and spare parts dealers.
