A Rational 1206.0261P Lock Washer resists loosening at fastened joints, keeping assemblies stable during repeated use.
The lock washer secures threaded fasteners by applying spring tension that resists loosening from vibration and repeated heating cycles in combination ovens and steamers. Its split construction matters because it maintains pressure against the mating surfaces, supporting a tighter connection and more consistent equipment assembly.
The lock washer may need to be replaced if fasteners can loosen during operation, panels or components begin to shift or recurring vibration affects equipment stability. Physical signs can include flattening, cracking, rust or loss of spring tension and environmental signs may include moisture exposure, heat stress or corrosion buildup around the fastening point.
