Screw 10-24 x 3/8″ 72091A
$2.99
Genuine Tacony OEM 10-24 x 3/8 inch screw (part# 72091A) used on the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S chassis. The short screw in the 10-24 family, and the short length is the point.
The Screw 10-24 x 3/8″ (part# 72091A) is a genuine Tacony OEM replacement part from the chassis assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the specified 10-24 screw at 3/8 inch length, used where the fastened stack-up is shallow.
What the Screw 10-24 x 3/8″ does
This is the screw for joints where there simply is not depth behind the hole. Three eighths of an inch is enough to develop full clamping in a thin stack and nothing more, which is exactly what you want when a longer screw would push through into a moving part or bottom in a shallow boss and jack the joint apart while feeling tight.
When to replace the Screw 10-24 x 3/8″ (72091A)
Replace it when the drive is rounded out, when the thread is stripped or has picked up material, or when it is corroded enough to bind on removal. A screw that spins freely without pulling the joint together has stripped its hole, and the hole is what needs attention.
Screw 72091A — fitment and installation notes
Keep the 3/8 inch screws separate from the longer 10-24 screws during a strip-down, because they are indistinguishable at a glance in a parts tray. Start it by hand, drive it straight, and tighten to a firm seat rather than to the limit of the driver. Tacony builds the Tornado Marathon SE 900 and the Powr-Flite Prowler PFX900S on a single machine platform, so this component carries across both brands rather than belonging to either one. It is a shared Tacony component and may fit additional models beyond those listed — call us and we will confirm against your serial number.
