A Southbend Range S05N-38 Lock Washer holds fastened parts firmly in place to maintain a secure connection during routine use.
The lock washer secures threaded fasteners by applying spring tension that resists loosening from vibration, movement and repeated equipment operation. Its split construction matters because it creates locking force and maintains clamping pressure more effectively than a plain washer in demanding service conditions.
The lock washer may need to be replaced if connected hardware repeatedly loosens, shifts during operation or can no longer stay firmly tightened under normal use. Physical signs can include flattening, cracking, corrosion, distortion or loss of spring tension and environmental signs may include exposure to moisture, heat, grease or vibration that could weaken its locking performance.
