Caterpillar 4B-1220 Screw – OEM-Grade Durability for Heavy Equipment

The Caterpillar 4B-1220 Screw is a precision-engineered component designed for optimal performance across a wide range of Caterpillar heavy machinery, including articulated dump trucks (models 4SD-D300B, 5WD-D250B, 2GD-D35C, 3FD-D35HP), earthmoving compactors (such as 57U-816, 15R-815, 91P-815, 15Z-816B), and excavators (including 32K-235, 51U-225, 2XC-215B). Manufactured to meet stringent OEM specifications, this screw features high-grade metallurgy that ensures superior resistance to wear and corrosion under extreme load conditions. Its precise dimensions and threading guarantee seamless integration with drivetrain and engine assemblies, contributing to reliable machine operation and extended service intervals.

Technically, the 4B-1220 screw is crafted from hardened alloy steel, optimized for high tensile strength and fatigue resistance. This makes it ideal for the demanding environments of earthmoving and excavation, where vibration and heavy mechanical stress are constant. The screw’s design supports efficient load distribution, minimizing the risk of loosening or failure during operation. By maintaining tight tolerances and using advanced heat treatment processes, this component enhances the overall durability and performance of your Caterpillar equipment, reducing downtime and maintenance costs.
