Quick overview

  • Factory fastener Sta-Rite part U30-542SS, not a hardware store substitute.
  • #8-32 thread Matches the tapped holes it came out of.
  • 7/8 inch long Length matters as much as thread on a pump housing.
  • Listed for Dyna-Pro pumps Carried under Sta-Rite Dyna-Pro and Dyna-Pro E pump parts.
  • Buy a spare Small screws are the piece that goes missing on the deck during a rebuild.
  • Corrosion counts Pump hardware lives in a wet, chemical environment, so replacing a rusted screw with the specified part is worth the small cost.

Product details

U30-542SS is the Sta-Rite cap screw in a #8-32 thread, 7/8 inch long. It is the factory fastener, carried under Sta-Rite Dyna-Pro and Dyna-Pro E pump parts.

Getting the size right

Thread and length both matter on a pump. A screw that is too long bottoms out before it clamps, and one that is too short strips the few threads it does catch. Ordering the specified part removes the guesswork on a housing you do not want to re-tap.

Worth a spare

Screws corrode, round off and disappear into the deck during a rebuild. Keeping an extra on the shelf costs very little and saves an unplanned trip in the middle of a job.

Questions and answers

What people ask about this product, answered by our pool techs.

What size is this screw?
A #8-32 thread, 7/8 inch long.
What is the part number?
Sta-Rite U30-542SS.
Which pumps use it?
It is listed under Sta-Rite Dyna-Pro and Dyna-Pro E pump parts.
Can I use a screw from the hardware store?
You can match the thread and length, but pump hardware sits in a wet, chemically treated environment, and the specified part is chosen for that. On a rebuild it is not worth saving a dollar here.
