Indeco MES Series High Strength Through Bolt And Side Bolt For Hydraulic Breaker Frame Assembly

Premium Fastening Components for Indeco MES Hydraulic Breakers

The Indeco MES Series Through Bolt and Side Bolt are precision-engineered fastening components designed for hydraulic breaker structural assembly. They are compatible with a wide range of Indeco MES Series hydraulic breakers and are widely used in construction, mining, quarrying, municipal engineering, road maintenance, demolition, and infrastructure projects.

Unlike ordinary industrial bolts, hydraulic breaker bolts operate under continuous impact loads, high-frequency vibration, and severe working conditions. They are responsible for keeping the breaker housing, front head, cylinder, back head, and side plates securely connected while maintaining the alignment of all internal components.

Our aftermarket replacement bolts are manufactured according to OEM dimensions, allowing customers to replace worn or damaged bolts without modifying the hammer body. Indeco and MES Series are used only to indicate product compatibility.

Material & Manufacturing

The durability of a hydraulic breaker depends greatly on the quality of its fastening system.

Our Indeco MES Series Through Bolts and Side Bolts are manufactured from premium alloy steels including:

• 42CrMo
• 40Cr
• 35CrMo
• Customized alloy materials upon request

Every bolt undergoes multiple manufacturing procedures including:

• CNC precision machining
• Thread rolling or precision threading
• Heat treatment
• Quenching & tempering
• Surface finishing
• Hardness inspection
• Dimensional inspection

These manufacturing processes improve tensile strength, fatigue resistance, impact resistance and service life while maintaining precise thread accuracy.

Product Features

Excellent Structural Strength

High-strength alloy steel allows the bolts to withstand continuous hydraulic impact and heavy-duty working conditions.

Accurate Thread Processing

Precision-machined threads ensure proper tightening torque and reduce the possibility of thread damage during installation.

Stable Hammer Assembly

Through bolts maintain the connection between the front head, cylinder and back head, while side bolts securely fasten the hammer housing and side plates.

Long Service Life

Optimized heat treatment improves wear resistance, fatigue resistance and structural reliability.

OEM Size Compatibility

Manufactured according to OEM specifications for direct replacement.

Excellent Corrosion Resistance

Surface treatment helps reduce corrosion during outdoor construction work.

Why High-Quality Through Bolts Matter

Many hydraulic breaker failures are not caused by major internal components but by loose or damaged fastening bolts.

When bolts lose preload or become stretched, the breaker body can gradually separate under repeated impact loads. This may result in:

• Hydraulic oil leakage
• Abnormal vibration
• Increased operating noise
• Uneven internal wear
• Seal damage
• Front head movement
• Cylinder misalignment
• Reduced impact energy
• Expensive repair costs

Replacing worn fastening bolts in time helps maintain the overall integrity of the hydraulic breaker and extends the service life of many other components.
