About this spa pump

The Allied Innovations Pump Faceplate Screw (90-401) is a genuine OEM replacement screw designed for spa and hot tub pump assemblies. This #8-32 x 5/8" stainless steel screw secures the pump faceplate to the motor housing on various spa pump models, ensuring proper alignment and preventing water infiltration into electrical components.

At Bubbles Supply, we stock only authentic Allied Innovations parts with our exact fit guarantee, so you know this screw will match your original hardware perfectly. Every order ships same-day when placed before our cutoff time, and we back all pump parts with our comprehensive 1-year warranty. When installing, ensure the pump is completely drained and power is disconnected before removing the old screw—these faceplates are under spring tension and require careful handling during reassembly.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Faceplate loose or wobbling on pump body
  • Water seeping past faceplate seal due to missing or stripped screw
  • Screw head corroded or sheared off during service
  • Faceplate screws won't torque down properly
  • Incomplete screw set after pump rebuild

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Count how many faceplate screws your pump uses — order the correct quantity
  • Inspect existing screws for thread damage; a stripped screw hole may need a helicoil insert before reinstalling
  • Confirm your existing faceplate screws are #8-32 thread pitch before ordering
  • Check screw head drive type (slot vs. Phillips vs. hex) to ensure your existing faceplate holes match this hardware
  • Verify the 5/8" length is appropriate for your faceplate thickness — thicker aftermarket faceplates may require a longer screw

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.

Install difficulty: Easy — DIY-friendlyTypically 15–30 minutes
