Truss head tapping screw secures panels, brackets, and covers in appliances. Replaces missing or damaged fasteners to restore snug fit and alignment.

This is a truss-head tapping screw used to secure trim, panels, and small assemblies on compatible LG appliances. It provides a low-profile, wide-bearing head that helps hold parts flush and resist pull-through. What it does:

• Fastens plastic and sheet-metal components where a self-tapping thread is needed
• Truss head spreads load to prevent damage to soft or thin materials
• Helps secure control panels, brackets, or trim pieces that require a low-profile head
• Common replacement when original mounting screws are missing, stripped, or corroded

• One truss-head tapping screw

• Use the correct screwdriver bit and moderate torque to avoid stripping the screw or workpiece
• Start threading straight and let the screw form threads without forcing at an angle
• Disconnect power and follow appliance-specific service safety procedures before working internally
• Replace any damaged mating threads or clips for a secure fit

A Tap-Tite binding-head screw used to fasten appliance panels and components where a self-tapping metal thread is required. Replaces missing or damaged fasteners to restore secure assembly and reduce vibration or rattling. What it does:

• Creates its own mating thread in thin sheet metal for a secure hold without a nut.
• Holds panels, brackets, and trim in place to prevent looseness or movement.
• Commonly used where stripped, missing, or broken screws cause rattling, misalignment, or parts that won't stay attached.
• Compatible with standard screwdrivers or nut drivers sized to the binding-head.

• Disconnect power and unplug the appliance before working on it.
• Use the correct driver bit to avoid cam-out or head damage.
• Start straight and apply steady pressure; avoid overtightening to prevent stripping the formed threads.
• If the original hole is badly damaged, assess for repair or use of a larger fastener as needed.

Button spring for microwave control panels. Replace when buttons feel unresponsive or stick. Verify your model number for proper fit before ordering.

This air duct channels exhaust air inside the appliance to help proper airflow and moisture removal. Replacing a cracked or clogged duct restores efficient venting and prevents leaks or airflow loss. What it does

• Directs air between the blower and vent housing to maintain proper airflow
• Helps remove moisture and lint from the appliance exhaust path
• Prevents exhaust air from escaping into the cabinet when intact
• Damaged ducts can cause reduced drying performance, unusual noises, or heat buildup

• One air duct

• Disconnect power (and gas if applicable) before beginning service
• Use basic hand tools to remove panels and fasteners; keep track of hardware
• Inspect adjacent seals, clamps, and the blower housing for wear and lint buildup
• Test operation after installation and check for proper venting and any leaks
