Double Tab Washers DIN 463
Double Tab Washers DIN 463 are locking washers designed to help prevent nuts, bolts and other threaded fasteners from loosening due to vibration, movement or repeated loading. Manufactured to DIN 463, these washers feature two locking tabs that can be bent into position after installation, creating a positive mechanical lock.
One tab is typically located against a fixed component or locating surface, while the second tab is bent against a flat of the nut or bolt head. This arrangement physically restricts rotation, making DIN 463 Double Tab Washers suitable for applications where maintaining fastener security is important.
What are Double Tab Washers?
Double Tab Washers, also known as two-tab locking washers or tab lock washers, are a form of mechanical locking washer. Unlike friction-based locking methods, the tabs are physically bent into position after the fastener has been tightened, helping to prevent unwanted rotation.
Their simple construction makes them suitable for machinery, assemblies and engineering applications where fasteners may otherwise loosen through vibration or operational movement.
