Parts Desk Insights
Best Use Case: Great for dress-style installations where you want the washer to sit neatly under the screw head and help protect the bearing surface.
Common Issues: Match washer size to the screw application—if the size is off, the head may not sit properly in the countersunk/finished area. Also inspect mating surfaces and existing fastener condition before reassembly.
