Key Features and Benefits

1. OEM-Level Precision Machining

Every 1076826 BOLT CATERPILLAR is produced with CNC-machined threading, controlled pitch, and optimized shank geometry. This guarantees a perfect fit with Caterpillar components without requiring modifications or recalibration.

2. High-Tensile Alloy Steel Construction

The bolt is manufactured from heavy-duty heat-treated alloy steel, with tensile strengths significantly higher than standard industrial bolts. This ensures:

• Exceptional load-bearing capacity

• Resistance to torsional stress

• Minimal risk of stretch, breakage, or thread deformation

3. Advanced Surface Coating for Corrosion Protection

The 107-6826 bolt receives a specialized anti-oxidation treatment, offering protection against:

• Moisture and humidity

• Road chemicals

• Salt exposure in mining operations

• Hydraulic fluid contamination

• Heat cycling and metal fatigue

This guarantees long-term durability, even in aggressive environments.

4. Precision Rolled Threads

Thread rolling enhances:

• Fatigue resistance

• Tensile strength

• Smooth installation

• Tight locking compatibility

This also prevents thread stripping and ensures consistent torque application.

5. Flanged Head Design

The bolt features a wide flange head to:

• Increase surface contact

• Distribute clamping pressure

• Prevent material indentation

• Improve joint stability

This design is ideal for heavy machinery with constant vibration and shock load.

6. Multi-Spline Drive Head

The head’s multi-spline pattern allows:

• High torque capacity

• Reduced risk of cam-out

• Secure tooling engagement

• Safe installation in confined environments

7. Zero-Maintenance Performance

Once installed, the 1076826 BOLT CATERPILLAR requires no additional calibration or tightening under normal working conditions. It is engineered to remain stable through thousands of work cycles.
