Screw (8-32 Thread)
Genuine Whirlpool part
By: Whirlpool
Part Number: WP3400892

Replacement 8-32-thread screw used to secure panels, brackets and small components in compatible household appliances. Restores missing or stripped fasteners so panels and parts stay firmly attached during normal use. What it does:

  • Secures trim, panels, brackets and control housings to maintain proper assembly.
  • Replaces missing or damaged screws that can cause rattling, loose panels or misaligned components.
  • Fits locations that require an 8-32 threaded fastener; correct length and head style for your application.
  • Helps restore stable, vibration-free operation when worn or stripped fasteners are replaced.
What's included: One screw. Install notes:
  • Disconnect power and water before servicing; wear eye protection and gloves.
  • Use the correct screwdriver or driver bit to avoid stripping the screw head.
  • Do not overtighten—turn until snug and secure to avoid damaging threads or surrounding parts.
  • If the original used a washer or nut, reuse or replace as needed and the screw length and head type match the original.
