$2.99
Genuine Tacony OEM 10-24 x 1/2 inch screw (part# 7BS001) used through the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S tank assembly. The correct length and thread for the joints it was specified for.
The Screw 10-24 x 1/2″ (part# 7BS001) 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 specified 10-24 machine screw used at several fastening points in the tank assembly.
What the Screw 10-24 x 1/2″ does
Length is the whole point of a screw part number. Too short and there is not enough thread engagement to hold under vibration; too long and the screw bottoms out or protrudes into a space where it can score a seal or a moving part. Keeping the specified screw in the specified hole is what stops a routine reassembly from creating a new fault.
When to replace the Screw 10-24 x 1/2″ (7BS001)
Replace it when the head is chewed out, when the thread is stripped or galled, or when it has corroded enough to bind on the way out. Any screw that had to be drilled or extracted should be replaced rather than cleaned up and reused.
Screw 7BS001 — fitment and installation notes
Do not substitute a longer screw because it was what was in the drawer. Where the screw threads into plastic, tighten to a firm seat only, and if the hole no longer holds, address the boss rather than driving a larger screw into it. 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.
