Description
A Lock washer exerts a spring force between the fasteners head and the substrate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to rotation.
These washers create a permanent installation and will lock on plastic, steel etc.
Metric Steel INTERNAL TOOTH Star Lock Washer
The internal teeth of this washer dig into the head of the screw or bolt as well as the mating surface for a strong, locked connection resistant to vibration.
Internal star washers have a smooth outer surface that will not catch or snag nearby items. The best fasteners to use with these washers have smaller heads such as JIS machine screws, cheese head screws, etc.
