Zimbabwe Sprocket Bolts and Nuts (Universal) For Crawlers (Excavator, Dozer, Loader...)
Sprocket segment bolts are high-strength fasteners (typically Grade 10.9 or 12.9, 40Cr steel) designed to secure crawler dozer and excavator drive segments. These components must withstand intense torque, vibration, and shear forces in harsh environments. Common sizes include M18*60, 7/8, and 3/4, with anti-seize recommended during installation.

Product Description
Key points of Sprocket Segment Bolts and Nuts:
- Material and Strength: Manufactured from hardened alloy steel to provide superior fatigue resistance and tensile strength.
- Common Applications: Primarily used on heavy machinery such as Caterpillar, Komatsu, Hitachi, and Doosan bulldozers and excavators.
- Maintenance Note: During installation, it is crucial to use high-pressure lubricant (like copper coat anti-seize) on the threads and ensure proper torque to prevent loosening.
- Key Part Numbers: Examples include 5P7665/7H3608 (CAT) and 09203-21860/01803-01824 (Komatsu).
- Types: Often feature a flat head (plow bolt style) or hex head, depending on the specific sprocket segment design.
- Surface Treatment: Often heat treated and coated (e.g., zinc plating) to enhance corrosion resistance and durability.
