Flat washers distribute load and prevent surface damage, while lock washers actively prevent fastener loosening through spring action. Lock washers are specifically designed for vibration-prone applications.
Install between the fastener head/nut and the joint surface. Ensure the washer is not over-compressed (should maintain spring action) and use proper torque specifications. Always follow manufacturer recommendations for specific aluminum alloy applications.
Generally not recommended. Lock washers lose their spring properties after compression and may not provide adequate locking force upon reinstallation. Always use new washers for critical connections.
