What is the Caterpillar 3B4506 lockwasher used for?

The 3B4506 lockwasher is designed to keep bolts and nuts securely fastened in Caterpillar machinery. Its split-helical design helps prevent loosening caused by vibration, heavy loads, or continuous machine movement, ensuring a reliable and stable connection between components.

To confirm compatibility, check your machine model, serial number, or existing part number. Many suppliers verify part fitment using Caterpillar service databases before shipping to ensure the replacement matches your equipment.
