Screw 1/4-20 x 3/4″ X8265
$2.99
Genuine Tacony OEM 1/4-20 x 3/4 inch screw (part# X8265) used on the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S chassis. A coarse structural thread for joints that carry the weight of the machine.
The Screw 1/4-20 x 3/4″ (part# X8265) 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 1/4-20 coarse thread screw at 3/4 inch length, used at chassis fastening points.
What the Screw 1/4-20 x 3/4″ does
Quarter inch coarse is the size that shows up where a joint has to carry load rather than just hold a cover on. The coarse pitch tolerates the slight thread damage and contamination that a chassis fastener inevitably picks up, and it drives cleanly into a tapped hole or a nut without the fussiness of a fine thread. Length is still specified rather than approximate, because a chassis joint that bottoms out is a joint that is not clamped.
When to replace the Screw 1/4-20 x 3/4″ (X8265)
Replace it when the drive is rounded, the thread is stripped, galled or bent, or corrosion has locked it into its hole. Any structural screw that had to be cut or drilled out is replaced as a matter of course.
Screw X8265 — fitment and installation notes
Tighten chassis fasteners in a sensible sequence rather than fully seating one before starting the next, so the parts pull together square. Use the specified locking hardware with it, and re-check these joints after the first few hours of service on a machine that has been apart. 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.
