Replacement machine screw used to secure appliance panels and internal components, restoring a stable fit and reducing rattling. Matches a 10-32 thread with a 17/32-inch length for original fastener locations. What it does:

• Fastens panels, trim pieces, and internal brackets; a missing or damaged screw can cause loose panels or rattling noises.
• Secures knobs, control housings and small assemblies to prevent wobble or misalignment.
• Restores proper fit for components so doors and access panels sit evenly and function reliably.

• Disconnect power (unplug or shut off circuit) before accessing components.
• Use the correct driver and tighten by hand; avoid overtightening to prevent stripped threads or cracked plastic.
• Keep any original washers or clips and reinstall them with the screw.
