A flat washer is a thin, disc-shaped plate with a hole in the center used to distribute the load of a threaded fastener, such as a bolt or nut.

In heavy-duty truck and trailer applications, 7/8-inch washers are commonly used on suspension components, fifth wheels, and axle U-bolts to prevent damage to mating surfaces and help maintain consistent clamping force. Replace washers when they show signs of deformation, corrosion, or cracking, or whenever you are installing new fasteners to ensure proper torque and joint integrity.
