Screw 1/4-20 x 1/2″ X8209
$2.99
Genuine Tacony OEM 1/4-20 x 1/2 inch screw (part# X8209) used on the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S chassis. The short 1/4-20, for joints with nothing behind them.
The Screw 1/4-20 x 1/2″ (part# X8209) 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 screw at 1/2 inch length, used where a heavy thread is needed in a shallow joint.
What the Screw 1/4-20 x 1/2″ does
Sometimes a joint needs the strength of a quarter inch thread but has almost no depth to give it. That is what this length is for. Half an inch develops enough engagement to hold a structural fastener while stopping short of anything behind the panel, which is why swapping in the longer 1/4-20 from the same drawer is a good way to punch through into something that was not meant to be touched.
When to replace the Screw 1/4-20 x 1/2″ (X8209)
Replace it when the head drive is rounded, when the thread is damaged or has pulled material out of its hole, or when corrosion has seized it. If it no longer draws the joint tight, the tapped hole or nut is the problem and needs to be sorted before a new screw goes in.
Screw X8209 — fitment and installation notes
Keep the two 1/4-20 lengths apart during a strip-down, because in the hand they are easy to confuse and the consequences differ. Fit the specified washers and locking hardware, and tighten in sequence with the rest of the joint rather than fully seating one fastener first. 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.
