Tab washers with long tab and wing are types of lock washers that are designed to provide a secure fastening solution in applications where vibration or movement may cause nuts or bolts to loosen.
These washers have a circular shape with a central hole to accommodate the bolt or screw. They also have one or more tabs that are bent up or down to create a locking mechanism. The long tab extends beyond the edge of the washer, providing additional stability and security.
The wing on the washer is an extension of the tab, which can be easily bent or folded over the nut or bolt head to further prevent loosening. This wing design allows for quick and easy installation without the need for additional tools.
Tab washers with long tab and wing are commonly used in automotive, aerospace, and industrial applications where vibration and movement are prevalent. They are particularly useful in high-stress environments where maintaining tight fastenings is critical for safety and performance.
