Frequently Asked Questions
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.
What are the key specifications of the 3B4506 lockwasher?
This lockwasher is typically made from durable steel and features a split-helical style that applies tension to maintain tightness. It has an approximate hole diameter of 0.382–0.398 inches, an outside diameter of 0.672–0.688 inches, and a thickness of about 0.115 inches.
Which Caterpillar machines commonly use the 3B4506 lockwasher?

Is the 3B4506 lockwasher an OEM or aftermarket part?
The 3B4506 is a high-quality aftermarket replacement engineered to meet or exceed OEM specifications. It delivers the same performance and fitment as the original at a competitive price. Contact Propel Parts if you need help confirming it\'s the right part for your machine.
Why are lockwashers important in heavy equipment assemblies?
Lockwashers help maintain consistent clamping force in fastened joints. In heavy equipment that operates under vibration and constant movement, they reduce the risk of bolts loosening, which can help prevent mechanical failures and costly downtime.

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.
When should the Caterpillar 3B4506 lockwasher be replaced?
Replace the 3B4506 when visible wear, leakage, or performance issues are detected during routine inspection. In high-demand applications, more frequent checks help catch early deterioration before it leads to larger failures.
