Parts Desk Insights
Best Use Case: Use for mounting applications where fasteners may be exposed to vibration and you want added resistance to loosening.
Common Issues: If a locknut feels difficult to start by hand, confirm thread pitch matches (5/16-24) and that the stud/bolt threads are clean. For best results, ensure the mating surface is properly seated and not cross-threaded.
