Before you buy — quick checklist

  • Measure your existing thumb screw length — confirm it's 1.75" tip to base
  • Check thread pitch and diameter against your existing screw before ordering
  • Inspect the threaded insert or receiver on your spa — if that's damaged, a new screw alone won't fix the problem
  • Confirm this is an OEM Master Spa application — aftermarket thumb screws may not match thread spec
  • Note whether your current screw is knurled, winged, or knob-style to ensure you're ordering the correct style

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