Lock washers are spring-type washers designed to prevent fastener loosening under vibration in aluminum profile corner connectors.
Lock washers are specialized fastening components used in aluminum profile corner connectors to maintain preload and prevent loosening of bolts or screws due to vibration, thermal cycling, or dynamic loads. They function by applying a continuous spring force against the fastener head/nut and the joint surface, compensating for material relaxation and maintaining clamping force.

这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
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.
