A Rational 1206.0120P Lock Washer Kit grips fastened parts to resist loosening and keep assemblies secure during regular use.
The lock washer kit holds fastened connections by biting into the mating surface and resisting loosening caused by vibration, movement and repeated heating cycles in combination ovens and steamers. Its external tooth design and 6.4MM inside diameter provide a firm mechanical grip and proper fit, which matters for maintaining stable assembly alignment and dependable equipment operation.
The lock washer kit may need replacement if mounted components can loosen, shift or rattle during operation, which could lead to reduced stability or inconsistent performance. Physical signs can include worn or flattened teeth, corrosion, cracking or deformation and environmental signs may include moisture exposure, heat stress or residue buildup around the fastened connection.
