Class Information
Number: 411/127
Name: Expanded, threaded, driven, headed, tool-deformed, or locked-threaded fastener > Threaded fastener locked to a discreet structure (e.g., plate, rail, wheel) > Fastener, or coaxial adjunct therefor, having sidewardly facing flat or formation engaged by portion of member (e.g., side lock) > Sheet metal member having resilient pawl distorted therefrom > Member abuts coacting part on substructure
Description: Device wherein the sheet metal member, or a part thereof, moves into engagement with, and is blocked by a particular region (e.g., an edge, a flange) of, or a specific formation (e.g., a lug) on, the substructure, in order to either eliminate or else minimize turning of the member relative to the substructure.
