Sta-Rite Motor Flange Bolt — 3/8-16 × 1" Stainless (RU354290SS / U30-74SS)

Genuine Sta-Rite / Pentair motor-flange bolt — the hex-head cap screw that holds the motor bracket to the seal-plate flange on the Sta-Rite Swimtec and Max-E-Pro pump family. Equivalent OEM reference U30-74SS. Thread 3/8-16, length 1 inch, full stainless steel construction — the SS grade is the reason to swap the original zinc-plated fastener on any pump service.

Fits every Sta-Rite Swimtec 5P4R / SW5P4R / 5P6R / SW5P6R pump plus the wider Max-E-Glas II, Dura-Glas II, Dyna-Glas, Dyna-Jet TPE, Max-E-Pro, IntelliPro VS/VSF and IntelliFlo families that share the same 5-inch square motor flange. Four bolts per pump.

Standard service item: replace all four bolts at once during any seal-plate service. A single seized bolt during a future teardown wastes as much time as the entire seal job, so full stainless is cheap insurance. Torque hand-tight in a cross pattern — over-torque strips the seal-plate boss.
