• Specification

• Function 

1. Secures Critical Components with High Tensile Strength
The primary function of this bolt is to fasten two or more components together, creating a rigid, non-loosening connection that withstands the extreme mechanical forces common in construction machinery. Unlike standard consumer-grade bolts, it is manufactured from high-strength alloy steel (often heat-treated to enhance durability) and designed to handle high tensile loads—such as the stress from an excavator’s boom lifting heavy materials, or a loader’s bucket scraping against hard surfaces.

2. Maintains Component Alignment Under Dynamic Stress
Komatsu heavy equipment operates in dynamic, high-vibration environments—from traveling over rough terrain to the repetitive motion of digging or loading. This bolt plays a key role in preserving the precise alignment of connected components, even under constant vibration and shock. Its threaded design allows for controlled torque application (when tightened to Komatsu’s specified torque values), creating a uniform clamping force that holds parts in their intended position.
