Dgcu105-4Bsb Parts

This lock washer secures fasteners and helps keep appliance panels and components from loosening during normal use, restoring a stable connection and reducing rattles or movement. What it does

• Grips under a screw or bolt to resist loosening from vibration and thermal cycling
• Helps keep panels, brackets, and small components securely fastened
• Commonly used where a screw or bolt must stay tight despite vibration
• Can reduce rattling noises and intermittent loose-part symptoms

• Disconnect power to the appliance before beginning any repair
• Replace with the same type and orientation of washer for proper locking action
• Use appropriately sized screw or bolt; do not mix with mismatched hardware
• Hand-start fasteners, then tighten to snug fit—avoid over-tightening which can deform the washer
