Screw 1/4-20 x 4-1/4″ X2405
$2.99
Genuine Tacony OEM Screw 1/4-20 x 4-1/4″ (part# X2405) for the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S. A long 1/4-20 screw that clamps through the deep joint it secures and holds it tight against constant vibration.
The Screw 1/4-20 x 4-1/4″ (part# X2405) is a genuine Tacony OEM replacement part from the recovery and solution tank assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the long 1/4-20 machine screw used as a through-fastener in the tank assembly.
What the Screw 1/4-20 x 4-1/4″ does
This is a 1/4-20 screw at an unusual 4-1/4 inch length, used where a fastener has to pass right through a stack of components and draw them together. Its length is the point: a shorter screw will not reach, and substituting one leaves the assembly clamped on only part of its thread.
When to replace the Screw 1/4-20 x 4-1/4″ (X2405)
Replace it when the thread is damaged, when it is bent, or when it is corroded enough that the drive rounds out. A long screw like this bends if the assembly is forced together misaligned, and a bent screw will never draw the stack down square.
Screw X2405 — fitment and installation notes
Do not substitute a shorter screw or a coarse-thread equivalent. Draw it down gradually, alternating with any neighbouring fasteners, so the stack pulls together evenly rather than pivoting on one corner. 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.
